In a large mixing bowl, measure out 2 cups of powdered sugar and 2 tablespoons of meringue powder. Whisk them together thoroughly until the mixture is smooth and free of lumps, creating a perfect base for your Sugar Cookie Icing.

Gradually pour in 5 tablespoons of water and 1 teaspoon of vanilla extract into the bowl with the dry mixture. Stir gently with a spatula until combined, making sure to scrape down the sides of the bowl.

Beat the mixture on medium speed for about 5 minutes until the icing turns smooth, glossy, and slightly fluffy. You’ll know it’s ready when it holds its shape and has a beautiful sheen.

If your Sugar Cookie Icing is thicker than desired, add more water, one tablespoon at a time, mixing well after each addition. Alternatively, if it’s too thin, gradually incorporate additional powdered sugar.

Evenly divide your icing into separate bowls, add in your chosen food coloring and mix until the colors are vibrant and uniform.

Using piping bags or a spatula, begin to decorate your cooled sugar cookies with the beautifully colored icing. Create fun designs, outlines, or intricate patterns.

After decorating, let the Sugar Cookie Icing set and dry completely, which will take around 6-8 hours. Place the cookies on a wire rack or parchment paper, ensuring they are spaced out to prevent sticking.
