What Is Royal Icing?
Royal icing is a smooth, hard-drying icing made primarily from powdered sugar, egg whites (or meringue powder), and water. Unlike buttercream frosting, which stays soft, royal icing dries to a firm finish, making it ideal for detailed designs, stacking cookies, and creating long-lasting decorations.
It’s commonly used for:
- Decorating sugar cookies
- Gingerbread houses or cookies
- Cake accents
- Piping intricate designs
My royal icing recipe below will help you create the best royal icing for all your cookie and cake decorating ideas.
Why Many Bakers Love Royal Icing
Royal icing may seem intimidating at first, but once you get the hang of it, it becomes an essential tool in your baking routine. With just a few ingredients and a bit of practice, you can transform simple cookies into stunning edible art.
Royal icing is popular for a reason—it’s both functional and beautiful.
Key Benefits:
- Dries hard and smooth for a polished look
- Perfect for detailed designs like lettering and florals
- Customizable consistency for outlining, flooding, and piping
- Long shelf life once dried
It’s the secret behind those bakery-style cookies you see all over Pinterest.
Royal Icing Ingredients
Making royal icing is surprisingly simple and requires just a few ingredients:
- Powdered sugar (confectioners’ sugar)
- Egg whites or meringue powder
- Water
- Vanilla or almond extract (optional for flavor)
Egg Whites vs. Meringue Powder
- Egg whites: Traditional method, gives a smooth finish
- Meringue powder: More convenient and widely used, especially for beginners
Most home bakers prefer meringue powder because it’s safer and easier to store.
Ways to use Royal Icing Beyond Cookies
Royal icing isn’t just for cookies—it’s a versatile decorating tool for many baked goods:
- Cake decorations and lettering
- Edible flowers and toppers
- Holiday-themed treats
- DIY edible gifts
Understanding Royal Icing Consistency
Consistency is everything when it comes to royal icing. You’ll typically use two main types:
1. Outline Consistency (Piping)
- Thick and holds its shape
- Used for borders and details
2. Flood Consistency
- Thinner and more fluid
- Used to fill in large areas smoothly
I usually make both an outlining consistency and flood consistency for each color I am working with. In the picture above, I mix my floods in the taller bottles, while my outliners are in the shorter bottles.
Pro Tip: Bakers often refer to “10-second icing”—this means when you drag a knife through the icing, it takes about 10 seconds to smooth out. This is ideal for flooding cookies.
Common Mistakes to Avoid when making Royal Icing
Even experienced bakers run into challenges with royal icing. Here are a few pitfalls to watch for:
- Icing too runny: Causes colors to bleed and lose shape. You can add more powdered sugar to correct this issue.
- Icing too thick: Difficult to pipe and spread. A bit more water a few drops at a time to thin the icing out.
- Air bubbles: Tap cookies gently to release trapped air. You can also use tooth picks, cake testers or anything pointy to pop the bubbles.
- Not covering icing: Royal icing dries quickly—always keep it covered. I use cling wrap right on the surface of the royal icing so it does not form a crusty skin.
Tips for Perfect Royal Icing Every Time
- Use gel food coloring for vibrant colors without thinning the icing
- Cover bowls with a damp cloth to prevent drying
- Use squeeze bottles or piping bags for better control
- Let cookies dry completely (6–12 hours) before stacking
- Practice on parchment paper before decorating cookies
How to Store Royal Icing
Short-Term:
- Store in an airtight container at room temperature for up to 1–2 days
Long-Term:
- Refrigerate for up to a week (re-mix before use)
- Freeze almost indefinitely. Thaw if when you want to use it.
Decorated Cookies:
- Store at room temperature in a sealed container for up to 1 week

Perfect Royal Icing
Equipment
Ingredients
- 3 tbsp meringue Powder or 3 pasteurize egg whites
- 6 tbsp warm water
- 1 tsp vanilla, peppermint, lemon, or coconut optional
- 4 cups powdered sugar plus more as needed
- gel food coloring This is my favorite gel food coloring kit
Instructions
- In a large bowl, add in the meringue powder, water, and flavoring (if using).
- Beat on medium speed to hydrate the meringue powder mixture until it is foamy (about 1-2 minutes).
- Add in the powdered sugar. Beat until light and fluffy. Royal icing will thicken the more you beat it. I prefer icing having stuff peaks as it will thin when you add food colorings. (If too thick, add a bit more water 1 teaspoons at a time.)
- Royal Icing all about consistency, so it is important to have a flood consistency (thinner and spreads out) and a piping consistency (thicker and holds it's shape).
- If you are coloring your icing, divide the icing into separate bowls and color them the colors you will need for your cookies. I usually squeeze a small dot of color and mix the the bowl until it is the shade I want.
