White Icing

I don't use white icing much, as i prefer cream cheese icing, but that doesn't go with all cakes. Here is my white icing recipe:

2 2/3 cup powdered sugar
1/3 cup butter (can use Crisco, but i hate that BLECK feeling on my tongue!)
2-3 Tbs milk
1 tsp vanilla

cream together to desired consistency.
