Divide whipped topping into thirds. In a large bowl, mix the pudding, and root beer flavored milk.. Mix well. Gently fold in ⅓ of the whipped topping (about 4 oz), until mixed. Pour into the graham cracker pie shell. Refrigerate until the pie is firm. Spread the remaining topping onto of the pie, as much as desired. Place into the freezer until firm. To serve, let pie thaw just enough to cut. Cut into pieces and garnish with cherries if desired
Notes
Orange Dreamsicle Pie: Use orange flavored milk instead of the root beer flavored milk.
