Dawson's Dirt Cake

20 oz. package of Oreo Cookies
8 oz. package of cream cheese
1/2 2stick of margarine
3 1/2 cups milk
2- 3 1/2 oz. packs of instant vanilla pudding mix
12 oz. Cool Whip
1 cup powdered sugar

Crush Oreos in blender. Mix cheese, margarine, and sugar in large bowl until blended. Add pudding and milk. Beat on low until thick. Stir in Cool Whip. Starting with Oreo crumbs, layer crumbs then layer pudding mixture. Use all mixture, but end with Oreos so they will be on top. This takes a very big bowl like a trifle bowl or punch bowl.
