Everyone thinks that this is my recipe and that I am fabulous for creating such greatness. But no. It is not mine. It is Betty's. Regardless, you should use it because this frosting is far superior to the stuff you buy in the store and it's super easy to make.
3 Cups powdered sugar
1/3 Cup stick butter, softened
1 1/2 tsp vanilla
1 to 2 TBS milk
Mix sugar and butter. Add vanilla and milk, and food coloring if you like. Beat well.
Frosts a 9X13 or fills and frosts one 8 or 9 inch two layer cake.
