Butter Cream Icing (Marge Clark)

This is from my internet friend, Marge Clark. It is a simple Butter Cream frosting to just dash together quickly for any cake!

Butter Cream Icing:

one stick soft butter (no substitutes)
1 tsp Vanilla,
perhaps 3 cups sifted confectioners sugar.)

whip the butter,
blend in the conf. sugar,
add a splash of cold milk.
if it is too thin, add more sugar, if too thick to beat, add more sifted sugar.
This is not a recipe this is a throw together.
Spread the frosting on top of the cooled cake. (don't try to frost a hot cake, don't ask how I know!). Marge cracks me up!!!! Don't ask how I know...LOL
