Kellie‘s Note
The Best Cookie Icing
My favorite thing to make when baking cookies for holidays and special occasions, it’s simple to make and easy to use. I’m showing you How to Make Royal Icing from Scratch with just a handful of ingredients you already have in your kitchen.
This is my go-to icing for just about any cutout cookie recipe like my favorite Gingerbread Cookies recipe. It’s fantastic year round for any occasion and it’s easy to color to fit any party.
Royal Icing from scratch is ready in just a few minutes and is a staple for cookie decorating…in my opinion and I can’t believe it’s taken me this long to share the recipe with you. I shared it first in this Cream Cheese Cutout recipe way back when and thought it’s awesome enough to warrant its own post. You’re going to love it!
Why You’ll Love This Royal Icing
- Smooth and glossy – It dries with that pretty bakery-style finish.
- Great for decorating – Use it for outlining, flooding, lettering, and simple details.
- Dries hard – Perfect for cookies you want to stack, package, or gift.
- Easy to adjust – Keep it thick for piping or thin it for flooding.
- Beginner-friendly – The consistency guide takes the guesswork out of decorating.
- Perfect for every occasion – Great for sugar cookies, gingerbread cookies, gingerbread houses, and holiday baking.
Ingredients For Royal Icing
- Pasteurized egg whites – Use carton egg whites or pasteurized shell eggs for a smooth, reliable icing.
- Powdered sugar – Also called confectioners’ sugar or icing sugar. This creates the sweet, sturdy base.
- Vanilla extract – Adds a simple bakery-style flavor. Use clear vanilla for bright white icing.
- Gel food coloring – Optional, but best for adding color without thinning the icing.
- Water – Use a few drops at a time when you need to thin the icing for flooding.
For the full ingredient list and instructions, see the recipe card below.
How to Make Royal Icing from Scratch
- Whip the egg whites – Add the pasteurized egg whites and vanilla to the bowl of a stand mixer. Beat on medium speed until frothy.
- Add the powdered sugar – With the mixer on low, gradually add the powdered sugar until fully incorporated.
- Beat until glossy – Increase the speed to medium-high and beat for 5 to 7 minutes, until the icing is glossy and holds stiff peaks.
- Adjust the consistency – Keep the icing thick for outlines and details. For flooding, stir in water a few drops at a time until a ribbon of icing disappears back into the bowl in 10 to 15 seconds.
- Color and decorate – Divide the icing into bowls, tint with gel food coloring, then transfer to piping bags or decorating bottles.
Kellie’s Royal Icing Tips & Troubleshooting
- Use gel food coloring – Liquid food coloring can thin the icing and change the consistency.
- Mix slowly when possible – Overmixing can create too many air bubbles and lead to a dull finish.
- Tap out air bubbles – Gently tap the bowl on the counter, then let the icing rest for a few minutes before piping.
- Use a fan on humid days – A small fan helps decorated cookies dry more evenly and keeps the finish shinier.
- If the icing is too thick – Add water a few drops at a time until it pipes smoothly.
- If the icing is too thin – Beat in a little more powdered sugar until it reaches the right consistency.
- If the icing is dull – Avoid overmixing and let cookies dry in a cool, low-humidity area.
- If the icing cracks – The icing may have been too thick or dried too quickly. Use a slightly thinner flood consistency and avoid drying cookies near direct heat.
Egg-Free Royal Icing Option
For an egg-free decorating icing, combine:
- 4 cups powdered sugar
- 3 tablespoons aquafaba
- 1/2 teaspoon vanilla or almond extract
Beat for about 5 minutes, until glossy and smooth. Adjust with a few drops of water for a thinner flood consistency.
This version works well for decorating cookies, though the texture and drying time can vary slightly from the egg-white version.
Can I Make Royal Icing with Meringue Powder?
Yes, but use a recipe developed specifically for meringue powder rather than swapping it directly for egg whites. Meringue powder brands vary, so the amount of powder and water needed can change from one product to another.
For this recipe, I use pasteurized egg whites because they create a smooth, glossy icing with simple grocery-store ingredients.
What Is Royal Icing?
Royal icing is a sweet decorating icing that dries into a smooth, firm finish. Unlike buttercream, royal icing hardens as it dries, making it perfect for detailed cookies, gingerbread houses, edible decorations, and cookies you want to stack or package.
Decorating 101: Royal Icing Consistency Guide
- Stiff consistency – Best for gingerbread-house glue, flowers, and decorations that need to hold their shape. The icing should form and hold a stiff peak.
- Outline consistency – Best for outlining cookies and piping details. The icing should be thick but still pipe smoothly.
- Flood consistency – Best for filling outlined cookies. Lift a spoonful of icing over the bowl and let it drizzle back in. The ribbon should disappear into the icing in about 10 to 15 seconds.
- To thin icing – Add water a few drops at a time, stirring well after each addition.
- To thicken icing – Beat in a little more powdered sugar until it reaches the consistency you need.
How to Keep Royal Icing From Drying Out
Royal icing starts to crust over quickly when it is exposed to air. Keep the bowl covered with plastic wrap pressed directly against the surface of the icing while you work.
If you are using piping bags, cover the tips with a damp paper towel whenever you take a break from decorating.
Is Royal Icing Safe to Eat?
Because royal icing is not cooked, I make this recipe with pasteurized egg whites. You can use pasteurized egg whites from a carton or pasteurized shell eggs.
If you have questions about a specific product, follow the safe-handling instructions on the package.
How Long Does Royal Icing Take to Dry?
Royal icing may feel dry to the touch in 1 to 2 hours, especially when piped in thin lines. Flooded cookies and thicker designs generally need 4 to 6 hours to set fully before stacking.
Humidity, icing thickness, and airflow all affect drying time. For the best finish, let decorated cookies dry uncovered in a cool, dry spot. A small fan can help speed up drying on humid days.
How to Store Royal Icing
Store leftover royal icing in an airtight container in the refrigerator for up to 3 days. Press plastic wrap directly onto the surface of the icing before sealing the container to prevent a crust from forming.
Bring the icing to room temperature before using, then stir or rewhip until smooth. If it has thickened, add water a few drops at a time until it reaches the right consistency.
Can You Freeze Royal Icing?
Yes. Transfer leftover icing to a freezer-safe bag or airtight container, press out as much air as possible, and freeze for up to 2 months.
Thaw overnight in the refrigerator, bring the icing to room temperature, and stir or rewhip before decorating.

Royal Icing FAQs
Does royal icing dry hard?
Yes. Royal icing dries into a smooth, firm finish that is ideal for decorated cookies, gingerbread houses, and edible decorations.
What is the difference between royal icing and buttercream?
Royal icing dries hard, while buttercream stays soft and creamy. Royal icing is best for cookie decorating, while buttercream is better for frosting cakes and cupcakes.
Can I make royal icing ahead of time?
Yes. Store it in an airtight container in the refrigerator for up to 3 days. Bring it to room temperature, then stir or rewhip before using.
Why is my royal icing too thin?
Add confectioners’ sugar a little at a time until the icing reaches the consistency you need. Outline icing should hold its shape, while flood icing should smooth back into the bowl in 10 to 15 seconds.
Why is my royal icing too thick?
Add water a few drops at a time, stirring well after each addition. A tiny amount of water can make a big difference.
Why is my royal icing dull?
Humidity and overmixing are common causes of dull icing. Avoid overmixing, let cookies dry in a cool, dry space, and use a small fan if your kitchen is humid.
Can I color royal icing?
Yes. Gel food coloring is best because it creates vibrant color without thinning the icing. Add a small amount at a time because colors often deepen as they sit.
Can I double this recipe?
Yes. Double the ingredients and use a large stand-mixer bowl so the icing has enough room to whip properly. Adjust the water slightly, if needed, to reach the consistency you want.
Can I use royal icing for a gingerbread house?
Yes. Use the icing at stiff consistency for a strong edible glue that will hold gingerbread-house pieces together.
How long will this keep in a airtight container? I mean can I make like quart and store what I don’t need for later use?
I usually like to use it within three days because it will begin to separate.
