1/2 c. brown sugar
1/2 c. or 1 stick butter

Boil together until well blended. Line jelly roll pan with graham crackers. Pour mixture over top and spread evenly. Sprinkle top with chopped nuts or coconut. Bake 8 to 10 minutes at 350 degrees. Check baking time often as these brown quickly. Remove from oven and transfer to waxed paper while warm. Cool completely. Will stay crisp.
