2 cups confectioners sugar, sifted

1/2 cup unsalted butter, room temperature

1 tsp vanilla extract

2 tablespoons milk or light cream

food colors, if desired

In an electric mixer, or with a hand mixer, cream the butter until smooth and well blended. Add the vanilla extract.  With the mixer on low speed, gradually beat in the sugar.  Scrape down the sides of the bowl.  Add the milk and beat on high speed until frosting is light and fluffy (about 3-4 minutes). Add a little more milk or sugar, if needed.  Tint the frosting with desired food color.
