Oh boy. That just sounds old to ME.
1 cup butter
3 cups powdered sugar
2 TBLS whole milk (I use 1 TBLS of half and half and 1 TBLS of 1% milk)
1 tsp vanilla
Cream the butter until fluffy. Add the powdered sugar and continue creaming until well blended. Add the vanilla and milk, and blend on low speed for 2 minutes. Add additional milk if needed. Beat at high speed until the frosting is fluffy.
*I added 1/4-1/2 cups of cocoa powder to make chocolate icing.
Cheers to celebrations!
