Ingredients
- 4 cups powdered sugar
- 3 egg whites or 4 tablespoons meringue powder
- 1 teaspoon lemon juice (optional)
- Water as needed
How to Make It
In a mixing bowl, beat the egg whites until frothy.
If using meringue powder, prepare it according to the package directions before continuing.Gradually add the powdered sugar and mix until combined.
Adding the sugar slowly helps prevent a cloud of powdered sugar and encourages a smooth mixture.Add lemon juice if desired.
The lemon juice gives the icing a subtle citrus flavor that balances its sweetness.Beat on high speed until stiff peaks form.
The finished icing should look smooth and hold its shape when the beaters are lifted.Adjust the consistency with water as needed.
Add water carefully to make the icing thinner for spreading or flooding. Use a thicker consistency for outlines and detailed designs.Use immediately to decorate cookies or store in an airtight container.
Keep the icing covered whenever you are not using it so the surface does not dry out.
How to Serve It
- Pipe the icing onto sugar cookies, gingerbread cookies, shortbread, or other sturdy decorated cookies.
- Use different colors of icing to create holiday designs, birthday themes, flowers, lettering, and intricate patterns.
- Finish decorated cookies with sprinkles, sanding sugar, edible glitter, or small candies before the icing sets.
How to Store It
Store leftover royal icing in an airtight container. Press plastic wrap directly against the surface of the icing before sealing the container to help prevent a crust from forming.
For best quality, refrigerate the icing if it contains egg whites. Stir it thoroughly before using, then adjust the consistency with water as needed. If the icing separates slightly, mix it again until smooth.
Freezing is not recommended when the icing contains raw egg whites because freezing and thawing can affect its texture. If using meringue powder, follow the storage guidance on the package.
Royal icing is not reheated. Instead, bring refrigerated icing back to a workable consistency by stirring it well and adjusting it with water as needed.
Helpful Tips
- Keep the icing covered. Royal icing dries quickly when exposed to air, so cover the bowl and decorating bags whenever possible.
- Add water gradually. A small amount can noticeably change the consistency, so add it carefully and mix thoroughly after each addition.
- Use the right consistency for the design. Thicker icing works well for outlines and details, while thinner icing spreads more easily inside outlined areas.
- Work on completely cooled cookies. Warm cookies can soften the icing and make detailed decorating more difficult.
- Let decorated cookies set before stacking. This helps protect the design and prevents smudging.
Optional Variations
- Add citrus flavor: Use the optional 1 teaspoon lemon juice for a bright, lightly tangy finish.
- Create colored icing: Divide the icing into separate bowls and add food coloring to create different shades for decorating.
- Add more flavor: Use a small amount of another baking-friendly flavoring in place of part of the liquid, while still adjusting the consistency with water as needed.
