¼ cup water
1 teaspoon vanilla extract
Food coloring (optional)
Instructions
In a mixing bowl, combine powdered sugar and meringue powder.
Add water and vanilla extract.
Mix until smooth, glossy, and well blended.
If desired, divide icing into separate bowls and stir in food coloring.
Use immediately to decorate cookies or store in an airtight container.
For outlining cookies, use a thicker consistency.
For flooding cookies, thin the icing with a few drops of water at a time.
Transfer icing to piping bags or squeeze bottles for easy decorating.
Let cookies sit uncovered at room temperature for several hours to harden.
Enjoy your beautifully decorated, firm-to-the-touch cookies!
Notes
For best results, allow decorated cookies to dry completely (about 6–12 hours).
Store leftover icing in an airtight container in the fridge for up to 1 week.
Stir well before reusing and adjust thickness with water or powdered sugar.
