How to Make It
In a large bowl, making sure there is no grease or oil residue in the bowl, mix the meringue powder and 4 tbsp of water using a hand mixer on high speed. Mix until completely dissolved and very frothy.
Add half of the powdered sugar. Mix on low until incorporated.
Add the other cup of powdered sugar along with the corn syrup and lemon powder or extract. Mix on low until combined, and then switch the speed to high and mix for 2 minutes, no less. Taste the icing and add more lemon flavor if desired.
The icing should be thick and have a little more volume as well. It should hold a soft peak.
Once mixed, grab a spatula and mix in the white food coloring or other colors as desired.
To thin out the icing, add ½ tsp of warm water at a time until the desired icing consistency is reached. For flood icing, aim for a consistency that settles in about 15–20 seconds. Mix with the spatula to avoid creating more air bubbles. You can make the entire batch flood consistency and then stiffen smaller batches as needed with more powdered sugar.
This step is optional but helps with air bubbles: Cover the bowl with plastic wrap and allow it to rest for 30 minutes. The majority of air bubbles will naturally release as the icing rests, giving you less trouble once your cookies are covered.
Decorate your cookies and allow them to dry uncovered overnight.
How to Serve It
- Use this icing to decorate sugar cookies for holidays, birthdays, showers, weddings, or other celebrations.
- Pair decorated cookies with coffee, tea, hot chocolate, or a glass of milk.
- Add colorful sprinkles, sanding sugar, edible glitter, or small sugar decorations while the icing is still wet.
How to Store It
Store leftover royal icing in an airtight container in the refrigerator. Press plastic wrap directly against the surface of the icing before sealing the container to help prevent it from drying out.
Before using refrigerated icing, allow it to come back to a workable consistency and stir it thoroughly with a spatula. Add a small amount of water if it has thickened too much, or add more powdered sugar if it is too thin.
Decorated cookies should dry uncovered overnight. Once fully dry, store them in an airtight container at room temperature, separating layers with parchment paper if needed.
Helpful Tips
- Make sure your mixing bowl and beaters are completely free from grease or oil, since residue can affect the icing’s structure.
- Add water gradually, using ½ tsp at a time. It is much easier to thin royal icing than to correct icing that has become too runny.
- Mix thinner icing with a spatula rather than a mixer to help avoid adding extra air bubbles.
- Letting the icing rest under plastic wrap for 30 minutes can help release most air bubbles before decorating.
- Keep finished cookies uncovered while they dry so the royal icing can set properly.
Optional Variations
- Replace the lemon extract with lemon juice powder for another bright lemon flavor.
- Omit the lemon flavor or adjust it to create a more neutral royal icing.
- Divide the icing into smaller portions and add different desired food colorings for multicolored cookie designs.
- Use the optional white food coloring to create a brighter white icing, especially when decorating with white designs.

Frequently Asked Questions
What consistency should royal icing have for flooding cookies?
For flood icing, thin the icing with warm water until it settles in about 15–20 seconds after being moved or stirred. Add water gradually, using ½ tsp at a time.
Why should the bowl be free from grease or oil?
Grease or oil residue can interfere with the icing’s structure and prevent it from becoming smooth and stable. Always use a clean, grease-free bowl and beaters.
Can I make the icing thicker after thinning it?
Yes. Add more powdered sugar to smaller batches until the desired thickness is reached. This works well for outlining and detailed decorations.
How long should decorated cookies dry?
Allow the decorated cookies to dry uncovered overnight so the royal icing has time to set completely.
Can I use lemon juice powder instead of lemon extract?
Yes. Lemon juice powder is a great ingredient to use in this royal icing and provides a bright lemon flavor.
