2 sticks of butter, softened
2 1/2 cups confectioner's sugar
1 tablespoon vanilla extract
1 tablespoon of milk, if needed
Beat butter in a medium bowl with mixer until creamy. Add confectioners’ sugar and vanilla and beat until fluffy. Mix in the milk if icing is too thick, and food coloring as desired. (I added more confectioner's sugar and milk to make the white look more white, it was a little brownish/yellow from the butter and vanilla). I mixed the red and blue separately then piped them together.
LOVE them! :)
