There's something magical about watching smooth, glossy royal icing transform plain sugar cookies into edible works of art. I remember the first time Logan and Ellie helped me decorate Christmas cookies , their little faces lit up as they piped wobbly snowflakes and hearts onto butter cookies. That batch wasn't perfect, but it sparked a tradition we now treasure every holiday season.
This royal icing recipe has become my go-to for every cookie decorating project. It's wonderfully simple , just three ingredients that come together in five minutes , but it creates that beautiful, hard-drying finish that makes decorated cookies look professional. Whether you're outlining delicate Valentine's Day hearts or flooding gingerbread men for your holiday cookie exchange, this icing delivers perfect results every single time.
What I love most is how forgiving it is. You can adjust the consistency from stiff peaks for detailed piping to a smooth flood that self-levels beautifully. I've tested this recipe countless times with both egg whites and meringue powder (I'll share both options below), and it works flawlessly with either method. Let's bake some cookies together!

What is Royal Icing?
Royal icing is a hard-drying decorative icing made from egg whites (or meringue powder), confectioners' sugar, and flavoring. Unlike buttercream frosting that stays soft and creamy, royal icing dries to a smooth, firm finish that won't smear or melt at room temperature. This makes it absolutely perfect for decorating sugar cookies, gingerbread houses, and any baked goods where you want crisp, clean designs that hold their shape.
The magic of royal icing lies in the egg white proteins. When you whip egg whites with powdered sugar, those proteins create a stable structure that hardens as it dries, forming that signature glossy shell. Professional bakers and cookie decorators have relied on this classic British icing for generations because it delivers consistent, beautiful results.
Royal Icing vs. Buttercream
While both icings are delicious, they serve different purposes. Royal icing dries hard and matte (or with a slight sheen), making it ideal for intricate designs, stacking cookies, and creating decorations that need to hold their shape. Buttercream stays soft and creamy, perfect for frosting cakes and cupcakes where you want that rich, buttery flavor and smooth texture. Think of royal icing as your decorating medium and buttercream as your eating frosting — though royal icing tastes wonderful too, with its sweet vanilla flavor and delicate crunch.
Ingredients for Royal Icing
The beauty of this recipe is its simplicity. You only need three basic ingredients to create bakery-quality royal icing at home. Here's what you'll need:
3 large egg whites (room temperature) — The protein in egg whites creates the structure that makes royal icing harden. I recommend using pasteurized eggs for food safety, especially if you're serving cookies to children or anyone with a compromised immune system. Separating eggs is easier when they're cold from the refrigerator, but they whip up better at room temperature. My trick? Separate them first thing, then let them sit on the counter for about 30 minutes before mixing.
1 pound confectioners' sugar (450g) — Also called powdered sugar, this dissolves quickly into the egg whites and creates that smooth, pipeable consistency we're after. Always sift your powdered sugar before adding it to the egg whites. This simple step prevents lumps and creates silkier icing. I learned this the hard way after spending 10 minutes straining clumpy icing through a mesh sieve!
1 teaspoon vanilla extract — Pure vanilla extract adds a lovely, delicate flavor that makes the icing taste as good as it looks. I always use real vanilla extract rather than imitation — the difference in flavor is noticeable, and it's worth the extra cost for something this simple.
Egg Whites vs. Meringue Powder: Which Should You Use?
This is the question I get asked most often about royal icing, and honestly, both methods work beautifully. The choice comes down to your specific needs and what you have available.
Egg Whites vs. Meringue Powder: Royal Icing Comparison
| Factor | Egg Whites | Meringue Powder | Winner |
|---|---|---|---|
| Taste | Better flavor, less "chemical" taste | Slightly artificial taste | 🥇 Egg Whites |
| Food Safety | Requires pasteurized eggs for raw consumption | 100% food-safe, no raw eggs | 🥇 Meringue Powder |
| Consistency | Can vary slightly batch-to-batch | Extremely consistent every time | 🥇 Meringue Powder |
| Shelf Life | 2 weeks refrigerated | 2 weeks refrigerated (powder lasts 2 years) | 🥇 Meringue Powder |
| Cost | $3-5 for dozen eggs | $8-12 for container (makes 20+ batches) | 🥇 Egg Whites (short-term) |
| Availability | Always in grocery stores | Must order online or specialty stores | 🥇 Egg Whites |
| Ease of Use | Requires separating eggs | Mix powder with water, no separation | 🥇 Meringue Powder |
| Drying Time | 6-8 hours at room temperature | 6-8 hours (identical) | 🤝 Tie |
| Best For | Home bakers, small batches, flavor priority | Professionals, large batches, consistency priority | Depends on needs |
Conversion: 3 egg whites = 3 tablespoons meringue powder + 6 tablespoons water
Egg whites produce better-tasting icing with a cleaner vanilla flavor, while meringue powder offers foolproof consistency and complete food safety. I use egg whites for small batches when we're decorating cookies at home — the flavor is noticeably better. For large holiday cookie swaps or when I'm making gingerbread houses for school events, I reach for meringue powder because it's safer for groups and delivers identical results every single time.
When to Use Egg Whites
Choose egg whites when you're making small batches (one or two dozen cookies), when flavor is your top priority, and when you have pasteurized eggs readily available. The taste difference is subtle but real — egg white royal icing has a purer, more delicate sweetness that I prefer for special occasion cookies.
When to Use Meringue Powder
Switch to meringue powder for large batches (three dozen cookies or more), when you need consistent results every time, when you're making icing ahead of time (the powder lasts two years in your pantry), or when serving cookies to children or immunocompromised guests. There's no raw egg concern, making it the safer choice for community events and bake sales.
How to Convert Between Egg Whites and Meringue Powder
The conversion is wonderfully simple: 1 egg white = 1 tablespoon meringue powder + 2 tablespoons water. For this recipe using 3 egg whites, you'd substitute 3 tablespoons meringue powder plus 6 tablespoons water. Mix the powder and water together first, then proceed with the recipe exactly as written.
How to Make Royal Icing (Step-by-Step)
Making royal icing is surprisingly quick and straightforward. The entire process takes about five minutes from start to finish, and you'll have smooth, glossy icing ready for decorating.
- Prepare your egg whites
If you're using fresh eggs, separate them carefully, making sure no yolk gets into the whites. Even a tiny bit of yolk can prevent the whites from whipping properly. I crack each egg into a small bowl first, then transfer the white to my mixing bowl — this way, if a yolk breaks, I've only lost one egg instead of contaminating the whole batch.
- Beat egg whites until frothy
Add your room temperature egg whites to the bowl of a stand mixer or a large mixing bowl. Using the whisk attachment (or a hand mixer), beat on medium-low speed for about one minute until the whites look foamy and frothy. You're not trying to create stiff peaks yet — just incorporating some air and breaking down the protein structure a bit.
- Gradually add powdered sugar
This is the most important step, so don't rush it. With your mixer running on low speed, slowly add the sifted confectioners' sugar about one-third at a time. Let each addition fully incorporate before adding the next. Dumping all the sugar in at once deflates those egg whites and creates a denser, less voluminous icing. Taking your time here makes a real difference in the final texture.
- Add vanilla extract
Once all the sugar is incorporated, pour in the vanilla extract. The icing will still look fairly loose at this point, but that's exactly right.
- Beat to stiff peaks
Increase your mixer speed to medium-high and beat for 3 to 5 minutes until stiff, shiny peaks form. You'll know it's ready when you lift the whisk and the icing stands straight up without drooping. The surface should look glossy and smooth, almost like marshmallow fluff. Don't over-beat (more than 5 minutes) or the icing can become dull and dry.
- Divide and color
Scoop portions of icing into separate small bowls if you're using multiple colors. Add gel food coloring one drop at a time, stirring gently until you reach your desired shade. Always color the icing while it's still at stiff consistency — this is important! If you thin the icing first and then add color, you risk the colors bleeding into each other on your cookies. Cover any bowls you're not actively using with plastic wrap pressed directly against the icing surface. Royal icing starts forming a crust within minutes when exposed to air.
Transfer your icing to piping bags fitted with small round tips (I love Wilton #2 or #3 for outlining, and #5 for flooding). Now you're ready to start decorating!
Royal Icing Consistency Guide
Getting the right consistency is truly the key to beautiful cookie decorating. This is where many bakers struggle, but once you understand the three main consistencies and how to achieve them, you'll feel confident tackling any design.
Stiff Consistency (Outlining and Piping Details)
This is your royal icing straight from the mixer — no water added. Stiff consistency holds a firm peak when you lift your spoon or spatula, standing straight up like a meringue. The icing should be thick enough that it doesn't flow or spread on its own.
When to use: Outlining cookie shapes, piping fine details and lettering, creating dimensional decorations, and adding texture to your designs. This consistency gives you precise control for detailed work.
How to test: Lift your spoon from the bowl. If the peak stands straight up without drooping or bending, you've got perfect stiff consistency. I tell Logan and Ellie it should look like little icing mountains!
Medium Consistency (Borders and Medium Details)
Medium consistency falls somewhere between stiff and flood — it's slightly thinned so it flows more easily but still holds some shape. When you lift a spoon, the icing falls back in ribbons that take about 10 to 12 seconds to smooth back into the surface.
When to use: Medium borders around cookies, filling in medium-sized details, and creating slightly raised elements that aren't quite as tall as stiff piping.
Water ratio: Add 1 to 2 teaspoons of water per cup of stiff icing, stirring gently after each addition. I actually prefer using a clean spray bottle to add water — it gives you much better control than pouring from a measuring spoon. Just give it 3 to 4 sprays, stir, and test.
How to test: The "count to 12" method works perfectly here. Drizzle a spoonful of icing back into the bowl. Count slowly — if the surface smooths out between 10 and 12 seconds, you're ready to go.
Flood Consistency (Filling Large Areas)
Flood consistency is your thinned royal icing that flows like thick honey and self-levels beautifully. This is what creates those smooth, professional-looking filled cookies you see at bakeries.
When to use: Filling in outlined areas on cookies, creating smooth backgrounds, and any time you want a flat, even surface that dries glossy and perfect.
Water ratio: Add about 1 tablespoon of water per cup of stiff icing. Again, I recommend adding it slowly — start with 2 teaspoons, test, then add more if needed. The spray bottle method works wonderfully here too.
How to test: This is the famous "10-second rule" in cookie decorating. Drizzle a spoonful of icing back into the bowl and count slowly to 10. The icing should settle and smooth completely by the time you reach 10. If it takes longer, add a tiny bit more water. If it smooths too quickly (before you reach 8), it's too thin — stir in a bit more powdered sugar.
How to Thin Royal Icing
The secret to perfect consistency is adding water drop by drop, not by pouring. I learned this after over-thinning more batches than I care to admit! Use a spray bottle or add water with a teaspoon, one small amount at a time. Stir gently between additions to avoid incorporating air bubbles, which can create a bumpy finish. Always test your consistency on a plate or piece of parchment paper before committing to your cookies.
If you accidentally make your icing too thin, don't panic. Simply stir in additional sifted powdered sugar, one tablespoon at a time, until you reach the right consistency. Just keep in mind that adding more than 2 tablespoons of sugar can start to make the icing clumpy, so it's always better to thin carefully from the start.
Pro Tips for Perfect Royal Icing
After decorating hundreds of cookies with Logan and Ellie over the years, I've picked up quite a few tricks that make the process smoother and the results more beautiful. Here are my favorite tips:
Room temperature egg whites whip better — I separate my eggs while they're cold from the refrigerator (they separate more cleanly that way), then let the whites sit on the counter for 30 minutes before mixing. This simple step creates more volume and fluffier icing.
Clean bowls are absolutely crucial — Any trace of grease or fat prevents egg whites from whipping properly. I wash my mixing bowl with hot, soapy water, then wipe it out with a paper towel dampened with white vinegar. This removes any residual oils that dish soap might leave behind.
Don't overmix — Once you reach stiff peaks, stop mixing. Over-beating causes air bubbles and creates a dull, less glossy finish. I set a timer for 4 minutes and check at the 3-minute mark to avoid going too far.
Add sugar gradually — I know I've mentioned this already, but it's so important I'm saying it again. Adding all the powdered sugar at once deflates your carefully whipped egg whites. Patient sugar addition maintains that lovely volume and creates lighter, more pipeable icing.
Cover immediately — Royal icing starts forming a crust within minutes of exposure to air. Press plastic wrap directly onto the surface of any icing you're not actively using. For piping bags, twist the top closed and clip it with a binder clip or rubber band.
Use gel food coloring — Liquid food coloring can thin your icing too much, especially if you're trying to achieve deep, vibrant colors. Gel colors are concentrated, so you need less, and they won't affect your consistency. I keep a set of Wilton gel colors in my baking drawer year-round.
Pop air bubbles before they dry — After flooding a cookie, look closely for tiny air bubbles on the surface. Use a clean toothpick to gently pop them before the icing starts to set. This creates a smooth, professional finish.
Work in sections — Keep unused icing covered with a damp cloth while you work. I place a damp paper towel directly over the bowls of icing I'm not currently using. This prevents crusting and keeps the icing fresh and smooth.
Mix on low speed — High-speed mixing breaks down the protein structure in egg whites too aggressively. Starting on low speed and only increasing to medium-high at the end creates better volume and more stable icing.
Always sift your powdered sugar — I mentioned this in the ingredients section, but it bears repeating. Sifting eliminates lumps that can clog your piping tips and creates silky-smooth icing that flows beautifully. I sift mine into a bowl before I even start separating eggs.
How to Use Royal Icing for Cookie Decorating
Once you've made your perfect royal icing and adjusted the consistency, it's time for the fun part — decorating! The classic method of "outlining and flooding" creates those beautiful, professional-looking cookies you see at bakeries and cookie shops.
Outlining Technique
Start with stiff consistency icing in a piping bag fitted with a small round tip (like a Wilton #2 or #3). Hold your piping bag at a 45-degree angle, with the tip just barely touching the cookie surface. Apply steady, gentle pressure and pipe a thin border around the entire edge of your cookie, following the shape. The goal is a continuous line about ⅛ inch from the edge — this border will hold your flood icing inside the cookie.
Work slowly and steadily. I like to lift the tip slightly off the surface as I pipe, letting the icing "fall" into place rather than dragging the tip along the cookie. This creates smoother, more even lines. When you reach your starting point, stop applying pressure and gently pull away.
Let your outline dry for 10 to 15 minutes before flooding. This is important! If you flood too soon, the outline can break or blend into the flood icing, losing that crisp definition.
Flooding Technique
Switch to your flood consistency icing (the thinner, self-leveling kind). You can use a piping bag or even a small squeeze bottle for this step — whatever feels most comfortable. Start in the center of your outlined cookie and work your way out to the edges, filling the entire outlined area with icing.
The flood icing should flow right up to meet your outline without going over. If you have gaps near the edges, use a clean toothpick to gently coax the icing into the corners. Work quickly because the icing starts to set within a few minutes.
As you work, watch for air bubbles rising to the surface. Pop them immediately with a toothpick. Once your cookie is completely flooded, let it sit undisturbed while the surface self-levels. This usually takes about 30 seconds to a minute. The icing will magically smooth itself out, creating that glossy, bakery-perfect finish.
Drying Time
This is where patience becomes essential. Royal icing needs proper drying time to achieve that hard, crisp finish.
Touch-dry: Your cookies will be dry to a light touch in 6 to 8 hours. At this stage, you can carefully add additional details or decorations on top without disturbing the base layer.
Fully hardened: Plan on 24 hours for royal icing to cure completely and reach its full hardness. I know it's tempting to stack or package cookies sooner, but rushing this step can cause smudging or denting.
How to speed up drying: Point a small fan toward your cookies (not directly on them, which can create ripples in wet icing, but nearby for gentle air circulation). This works especially well in humid environments where icing can take longer to set. I also find that moving cookies to a cooler, drier room helps significantly.
Temperature and humidity impact: High humidity is the enemy of royal icing. On rainy or humid days, drying can take twice as long, and your icing might not achieve the same glossy finish. If you live in a humid climate, working in an air-conditioned room or using a dehumidifier makes a real difference.
Royal Icing Consistency Problems & Solutions
Even experienced bakers run into royal icing challenges. The good news? Almost every problem has a quick fix. Here's my troubleshooting guide for the most common issues:
| Problem | Cause | Quick Fix | Prevention |
|---|---|---|---|
| Too Runny | Too much water added | Add powdered sugar 1 tablespoon at a time (stop at 2 tablespoons max or it gets clumpy) | Use spray bottle for water; add drops at a time, testing between additions |
| Too Thick | Not enough liquid | Add water using spray bottle, 3-4 sprays at a time, stirring gently | Measure water carefully; always err on the side of less |
| Clumpy / Lumps | Added sugar too quickly OR sugar wasn't sifted | Strain through fine-mesh sieve; don't add more sugar to fix runniness | ALWAYS sift powdered sugar before adding; add sugar gradually |
| Won't Dry | Too much water OR high humidity | Move to cool, dry room with fan; let sit full 24 hours | Use proper water ratios; avoid decorating on humid days |
| Dries Too Fast | Too little water OR very dry climate | Cover with damp towel immediately; add drop of water to revive if needed | Keep piping bags sealed; work in small batches; cover bowls with plastic wrap |
| Color Bleeding | Added color AFTER thinning OR icing too wet | Add gel color to stiff icing FIRST, then thin with water | Always color at stiff consistency before adjusting for flooding |
| Border Breaks | Icing too thin for outlining | Use stiff consistency with no water added; test on parchment first | Keep separate bowls: stiff for outlining, flood for filling |
| Not Shiny | Over-mixed OR dried too slowly in humid conditions | Mix only until stiff peaks form (4 minutes max); use fan to speed drying | Beat just until peaks form; don't over-whip; ensure good air circulation |
The number one mistake I see home bakers make is adding water too quickly. That spray bottle trick I mentioned earlier? It's genuinely changed my cookie decorating game. Three or four sprays, stir, test, repeat. Taking it slow prevents you from crossing that line from "perfect flood consistency" to "way too thin."
Another game-changer: always add gel food coloring to your stiff icing BEFORE thinning with water. I learned this after watching red icing bleed into white icing on a batch of Valentine's cookies. Coloring first and then thinning maintains the proper ratios and prevents that frustrating color bleeding problem.
Pro Tips for Consistency Control
Keep one master bowl of stiff icing and scoop portions into smaller bowls to thin separately. This way, if you over-thin a batch, you haven't ruined all your icing.
Weigh your powdered sugar for accuracy. A pound should be exactly 450 grams — but a "pound" measured in cups can vary by 50 grams or more depending on how compacted the sugar is. That variation affects your final consistency more than you'd think.
Consider investing in a small kitchen scale. I resisted for years, but once Logan helped me measure ingredients by weight for a school baking project, I was converted. The consistency of my royal icing improved immediately because I was working with exact measurements every single time.
Storing Royal Icing
Proper storage keeps your royal icing fresh and ready to use for weeks. Here's how I store mine:
Short-Term Storage (Up to 2 Weeks)
Transfer unused royal icing to an airtight container or keep it in the piping bag, sealed tightly with a rubber band or binder clip. Press plastic wrap directly onto the surface of the icing to prevent a crust from forming. Store in the refrigerator for up to two weeks.
Before using refrigerated icing, let it come to room temperature for about 30 minutes. If it seems too stiff, you can re-whip it briefly or add a drop or two of water to restore the consistency. Sometimes the icing separates slightly during storage — a quick stir usually brings it back together beautifully.
Long-Term Storage (Up to 3 Months)
Royal icing freezes wonderfully. Transfer it to a freezer-safe container, press plastic wrap directly on the surface, then seal with an airtight lid. Freeze for up to three months.
To use frozen icing, transfer it to the refrigerator to thaw overnight. Once thawed, let it come to room temperature, then re-whip if the consistency has changed. You might need to add a tiny bit of water to restore the perfect texture, but frozen royal icing works almost as well as fresh.
Storing Decorated Cookies
This is equally important — you've spent all that time decorating, so you want those cookies to stay perfect! Let your royal icing dry completely before storing (remember that full 24-hour cure time). Layer cookies between sheets of parchment paper or wax paper in an airtight container.
Royal icing decorated cookies stay fresh at room temperature for up to two weeks. Don't refrigerate decorated cookies — the moisture can make the icing weep or become sticky. Also avoid storing them in humid environments, which can prevent the icing from maintaining its crisp texture.
For gift-giving or shipping, place each completely dry cookie in a clear cellophane bag, then pack them carefully in a sturdy box with plenty of cushioning. The royal icing is quite durable once fully hardened, but it can crack if cookies bump together during shipping.
Royal Icing Recipe Variations
While the classic vanilla royal icing is perfect for most decorating projects, these variations add extra flavor and accommodate different dietary needs.
Meringue Powder Royal Icing
As we discussed earlier, meringue powder creates consistent, food-safe royal icing that's perfect for large batches. To make this variation, replace the 3 egg whites in the recipe with 3 tablespoons meringue powder plus 6 tablespoons water. Mix the powder and water together first until completely dissolved, then proceed with the recipe exactly as written. The result is nearly identical to egg white royal icing, with perhaps a slightly less pronounced vanilla flavor.
The benefits are significant: no separating eggs, no food safety concerns about raw eggs, and incredibly consistent results batch after batch. I keep a container of meringue powder in my pantry specifically for those times when I'm making cookies for school events or bake sales.
Flavor Variations
While vanilla is traditional, other extracts can add a lovely twist to your royal icing:
Almond extract — Replace the vanilla with ½ teaspoon almond extract (it's stronger than vanilla, so you need less). This pairs beautifully with sugar cookies and adds a subtle, sophisticated flavor.
Lemon extract — Use ½ to ¾ teaspoon lemon extract for a bright, citrusy note. This is wonderful on spring cookies or paired with lemon sugar cookies.
Peppermint extract — Perfect for Christmas and winter holiday cookies. Start with ¼ teaspoon and taste — peppermint is quite strong. This makes the whole kitchen smell amazing while you're decorating!
Vegan Royal Icing Alternative
For those avoiding eggs, aquafaba (the liquid from a can of chickpeas) can replace egg whites in royal icing. Use 3 tablespoons (about 45ml) of aquafaba in place of the 3 egg whites. Whip it exactly as you would egg whites, and proceed with the recipe.
Fair warning: the results aren't quite identical to traditional royal icing. Aquafaba icing takes longer to reach stiff peaks (sometimes 8 to 10 minutes of beating), and the dried icing can be slightly more fragile. However, it's a workable option for vegan bakers or those with egg allergies. The flavor is very similar, and with careful handling, it creates beautiful decorated cookies.
This royal icing recipe delivers perfect results every time, whether you're decorating sugar cookies for a holiday party or building an elaborate gingerbread house with the kids. The beauty of royal icing is its versatility — you can create delicate, detailed designs or bold, colorful patterns, all with the same basic recipe adjusted to different consistencies.
I hope this becomes your go-to cookie decorating icing, just like it has for our family. There's something wonderfully therapeutic about piping designs onto cookies, watching the icing flow and settle into perfect smoothness. Logan has gotten so good at flooding cookies that his work rivals the decorated cookies we see at our local bakery.
Whether you choose egg whites or meringue powder, remember that practice makes perfect. Your first batch might not look bakery-perfect, but each time you decorate, you'll get a little better, a little faster, and more confident in your technique. Don't be afraid to experiment with colors, patterns, and designs. Some of our favorite cookies have been the "happy accidents" that turned into new family traditions.

Easy Royal Icing Recipe (Perfect for Cookie Decorating!)
Great for outlining and flooding, this foolproof royal icing recipe comes together quickly and easily. Cookie decorating has never been easier.
- Prep Time: 5 minutes
- Cook Time: 0 minutes
- Total Time: 5 minutes
- Yield: 36 servings (about 3 cups) 1x
- Category: Frosting
- Method: No-Cook
- Cuisine: British
Ingredients
- 3 large egg whites (room temperature) OR 3 tablespoons meringue powder + 6 tablespoons water
- 1 pound confectioners' sugar (450g), sifted
- 1 teaspoon vanilla extract
- Gel food coloring (optional)
Instructions
- In the bowl of a stand mixer or large mixing bowl, beat egg whites on medium-low speed until frothy, about 1 minute. The egg whites should look foamy with small bubbles throughout.
- With the mixer on low speed, slowly add confectioners' sugar about one-third at a time, letting each addition fully incorporate before adding more. Add the vanilla extract with the final third of sugar.
- Once all sugar is fully incorporated, increase speed to medium-high and beat until stiff, shiny peaks form, 3 to 5 minutes. When you lift the whisk, the icing should stand straight up without drooping.
- Divide icing among small bowls and add gel food coloring if desired, stirring gently to incorporate. Keep any icing that isn't being immediately used covered with plastic wrap pressed directly on the surface, as it dries out very quickly.
- For flooding consistency, add water to individual portions using a spray bottle or adding by the teaspoon, stirring gently after each addition until the icing flows like thick honey and self-levels in about 10 seconds.
- Transfer to piping bags fitted with appropriate tips and decorate cookies. Outline first with stiff consistency, let dry 10 to 15 minutes, then flood with thinned icing.
Notes
Eggs are easier to separate when cold, but egg whites whip better at room temperature. Separate in advance if possible. Whipping by hand is possible but takes much longer. Add sugar gradually for better volume. Always use a clean, grease-free bowl. Use gel food coloring to avoid thinning the icing. To revive thickened icing, add water sparingly. Real vanilla extract gives the best flavor. Outline cookies first with stiff icing, then flood with thinned icing. Adjust flooding consistency with a few drops of water at a time and test on parchment before decorating.
