Graham's

1/2 c. butter
1/2 c. margarine
1/2 c. sugar
Boil these three ingredients for 1 minute and pour over graham crackers broken into four pieces and spread in a 9 x 13 pan. ( I like to cover the pan with tin foil.) Bake for 8-9 minutes at 350 degrees or a little longer if you like them crunchy.
