How Do You Make Cookie Icing Quickly?
To make cookie icing quickly, melt 1/4 cup of butter in a microwave-safe bowl. Gradually stir in 2 cups of powdered sugar and 2 tablespoons of milk until smooth. If the icing is too thick, add more milk; if too thin, add more sugar. Add food coloring or extracts for flavor. Drizzle or spread on cookies and let dry.
