1 graham cracker pie crust (or chocolate)
1 lg. box instant chocolate pudding & pie filling
1 c. milk
2 c. Cool Whip

Mix pudding and milk. Stir until thickened. Add 2 cups Cool Whip, mix until blended. Pour into pie crust and cover with remaining Cool Whip. Grate chocolate bar over the top for decoration. Chill for 1 hour. (My favorite.)
