2/3 cup unsalted butter, softened
2 2/3 cups confectioner's sugar
2 to 3 tablespoons milk
3/4 teaspoon vanilla extract
food coloring (red, white, green)
Beat butter, sugar, milk and vanilla in a mixer until smooth. If frosting
is too thick, add a little more milk. Divide frosting into several small
bowls. Add a different color of food coloring to each bowl. Mix.
Glaze each cookie the holiday colors of your choice.
