(Note: Cass makes this more by guess and by gosh, so you may have to tweak the ingredients just a little.)
Ingredients:
2 ½ cups powdered sugar
(sometimes Cass adds a little more)
¼ cup butter
2 tbsp milk (The amount really depends on whether you end up adding a little more powdered sugar.
Conversely, if your frosting is a little too sloppy, throw in some more powdered sugar.)
½ tsp vanilla
Directions:
Put butter in a mixing bowl and sift in powdered sugar. Add milk and vanilla and cream together until smooth.
