2/3 cup softened butter
4 cups sifted powdered sugar (icing sugar)
2 tablespoons milk
1 teaspoon vanilla extract
Mix all ingredients with an electric mixer until fluffy. Add chosen decoration after frosting the cookie, cupcake, cake, or other baked good. Enjoy!
Tip: at your local baking goods store, they should have frosting bags and nozzles. They can make cool designs.
