Ingredients
Scale
- 4 cups powdered sugar, sifted
- 3 tablespoons meringue powder
- 6 tablespoons warm water (approximate)
- 1 teaspoon vanilla extract
- Optional: Gel food coloring
Instructions
- In a large bowl, whisk together the sifted powdered sugar and meringue powder until fully combined.
- Add the vanilla extract and 5 tablespoons of the warm water to the dry ingredients.
- Using an electric mixer on low speed, mix until the ingredients are just combined. Scrape down the sides of the bowl.
- Increase the mixer speed to medium-high and beat for 5 to 7 minutes until the icing is very smooth, bright white, and holds stiff peaks. This whipping action incorporates air, which helps it dry hard.
- Check the consistency. If the icing is too thick for outlining, add the remaining tablespoon of water, one teaspoon at a time, until you reach a thick, pipeable consistency.
- To achieve a thinner consistency for flooding, add water one teaspoon at a time until the icing flows smoothly off the whisk and disappears back into the bowl after counting to 10.
- Divide the icing into separate bowls for coloring, if desired. Add gel food coloring sparingly and mix until the color is uniform.
- Use the stiff consistency icing for outlining cookies. Let the outline dry for 15 to 30 minutes before filling in the center with the thinner flooding consistency.
- Allow the icing to dry completely at room temperature. This can take 6 to 12 hours depending on humidity and thickness. The icing is ready when it is hard to the touch and has a glossy finish.
Notes
- For a **glossy cookie icing finish**, avoid adding too much liquid. The meringue powder is key to getting that hard, professional set.
- If you need an **icing without corn syrup for cookies**, this recipe works well, relying on meringue powder for structure.
- To make your cookies **stackable and gift-ready**, ensure the icing is completely dry before stacking or packaging.
- If you see air bubbles after mixing, gently tap the bowl on the counter or use a toothpick to pop them before applying the icing.
