Fudge Frosting

This is my ALL TIME favorite chocolate frosting recipe.  My mom has been making it since before I can remember.

Boil or put in Microwave:

1 Cube Butter

4 TBL Cocoa

6 TBL Milk

Then add:

4 Cups Powdered Sugar

Walnuts

1 tsp Vanilla

Poor over cake and let set.  If you want a spreadable version don't boil just use room temp butter.
