Butter Frosting

4 T butter
2 1/3 c powdered sugar
milk
¾ tsp vanilla
for chocolate frosting add 3 T cocoaPut butter in bowl and beat with electric mixer until fluffy. Add about half the powdered sugar. Beat in 1 T milk and the vanilla. Slowly add in the rest of the powdered sugar. Add more milk if needed. Add food coloring if desired. This makes enough frosting to ice half of a cake mix, so I usually double it.
