BUTTER FROSTING
(enough for top & sides of 2-layer round cake)

6 Tbsp butter
4 1/2 to 4 3/4 c powdered sugar
1/4 c milk
1 1/2 tsp vanilla

In a small mixer bowl beat butter until light and fluffy.  Gradually

and vanilla.  Gradually beat in the remaining powdered sugar, then
additional milk, if necessary, to make frosting of spreading
consistency.
