A delicious peanut butter dessert, no baking required.
In a mixing bowl, beat the cream cheese and sugar together, then mix in the peanut butter and milk. Beat all that stuff until it's a single smooth mixture, then fold in the whipped topping.
Spoon the mix into two 9 inch graham cracker pie shells, put covers over them, and leave them in the freezer for at least two hours or until firm.
