Why Make This Recipe
- Simple ingredients: Powdered sugar, egg whites or meringue powder, vanilla extract, and water are all you need.
- Easy to customize: Adjust the amount of water to create thicker icing for outlines or thinner icing for flooding.
- Perfect for decorating: The icing becomes firm as it dries, making it ideal for detailed cookie designs.
- Great for special occasions: Use it for holidays, birthdays, weddings, and everyday baking projects.

Ingredients
- 4 cups powdered sugar
- 3 large egg whites or 5 tablespoons meringue powder
- 1 teaspoon vanilla extract
- Water as needed
How to Make It
Combine the powdered sugar and egg whites or meringue powder. In a large mixing bowl, combine powdered sugar and egg whites (or meringue powder) and beat on high speed until the mixture is thick and holds stiff peaks.
Add the vanilla extract. Add vanilla extract and mix until combined.
Adjust the consistency. If the icing is too thick, add a few drops of water until you reach the desired consistency. Add the water gradually so the icing does not become too thin.
Use or store the icing. Use immediately for decorating cookies, or store in an airtight container to prevent drying.
How to Serve It
- Pipe the icing onto sugar cookies, gingerbread cookies, or shortbread cookies.
- Use it to create outlines, filled designs, lettering, flowers, and other decorations.
- Add colorful sprinkles, sanding sugar, or edible decorations while the icing is still wet.
How to Store It
Store leftover royal icing in an airtight container to prevent drying. Press plastic wrap directly against the surface of the icing before sealing the container for extra protection.
Refrigeration may be used for storage, especially when preparing the icing ahead of time. Before using refrigerated icing, allow it to soften as needed and mix it thoroughly to restore a smooth consistency. Add a few drops of water if it has thickened too much.
Freezing is not specified for this recipe. For the best texture and decorating results, prepare and use the icing fresh whenever possible.
Helpful Tips
- Add water slowly: A few drops can make a noticeable difference, so adjust the consistency gradually.
- Keep the icing covered: Royal icing dries quickly when exposed to air. Cover the bowl or transfer the icing to an airtight container whenever you are not using it.
- Check for stiff peaks: Beat the mixture until it is thick and holds stiff peaks before adding water for a thinner decorating consistency.
Optional Variations
- Replace the vanilla extract with another suitable flavoring, such as almond or lemon extract, for a different flavor profile.
- Divide the icing into separate bowls and add food coloring to create different decorating colors.
- Adjust the amount of water for different uses, keeping the icing thicker for outlines and making it thinner for filled designs.
