Another one from Aunt Elaine that I tried for the first time last year. It was a big hit.
Line 15 x 10 x 1 pan (jelly roll pan) with foil. Place graham crackers on the bottom. Heat oven to 350.
1/2 c. sugar
1 stick butter
1 stick margarine
(or both butter)
Bring to a full boil and cook for 3 minutes. Pour mixture over graham crackers. Bake at 350 for 8 minutes. Cool and break into pieces. This is NOT low fat.
