1 package Oreos
1/2 stick butter
1 1/2 cups cold milk
2 packages (4-serving size) vanilla-flavored instant pudding
1 8-oz. tub Cool Whip, thawed
Crush 24 to 28 cookies (You can use a blender if you wish). Mix with melted butter and pressed onto the bottom and sides of a 9-inch pie plate.
Beat milk and pudding together for 1-2 minutes, or until thick. It will be pretty thick, almost like a custard. Carefully stir in whipped topping and blend well.
Crumble 12 Oreo cookies (more if you like) and fold into the pudding mixture. Spoon into crust.
Decorate with Oreos as you wish and refrigerate for at least four hours. Enjoy!
