Make chocolate pudding according to package directions and let it set in the fridge.
Crush the whole package of cookies either with a food processor, or in a bag with a rolling pin. Save 1/2 cup to sprinkle on top of dessert when it's done.
Mix remaining crumbs and melted butter together. Pour crumb mixture into a 13x9 pan. Press crumbs into the bottom of the pan to make a crust.
In a mixing bowl, blend cream cheese until nice and smooth and then add powdered sugar; mix well. Fold in 1 tub of cool whip.
Top Oreo crust with cream cheese mixture, then pudding, then your last 8 oz. tub of cool whip. Sprinkle remaining Oreos on top.
Cover and refrigerate until ready to serve.
