1 pkg. instant sexy vanilla pudding
1 1/2 c. half & half or milk
8 oz. Cool Whip (thawed)
1 c. Heath bars, chopped (about 4)
Graham cracker crust

Mix pudding and half & half or milk with wire whisk for 1 minute. Let stand for 3 minutes. Fold in Cool Whip and Heath bars. Spoon into graham cracker pie crust. Freeze 6 hours or overnight. Let thaw 1/2 hour before serving.

I doubled the recipe and put it in a 9 x 13 pan with graham cracker crust.
