This recipe may not be as 'old as the hills' but it's close. It's as old as your Great Grandmother anyway! Top these with a simple chocolate icing made from powdered sugar, butter and a little vanilla along with either about 1 1/2 squares melted chocolate or some cocoa powder. The amount of chocolate is up to your own tastes.
