Hershey's One Bowl Buttercream Frosting

This came from the side of a Hershey's Cocoa Tin from the 80's. I don't know if this is posted anywhere on this site, but I wanted to keep it for my files. Please note the amount of cocoa you add to the frosting - There are different amounts listed for the chocolate intensity you would like your frosting to taste
