Prepare your instant chocolate pudding per the package directions (every brand requires different amounts of milk, so follow the instructions for your package. Just be sure you are using INSTANT pudding)
Pour a little less than half of your chocolate pudding into the bottom of your graham cracker pie crust.
Mix the remaining pudding with 1/2 of the whipped cream and stir well.
Add as the next layer of pie.
Add 1/2 of the remaining whipped cream to the top of the pie.
Using a potato peeler shave off chocolate pieces to add to the top of your pie.
