Crush 2/3 of a package of Oreo cookies and mix with 1/2 stick of melted butter. Press into bottom of a 9x13 inch pan, reserving 1/2 cup of mixture to use on topping. Combine both puddings with 3 1/2 cups of milk and mix on high speed for 2 minutes. Add 8 ounces of Philadelphia cream cheese and 1 medium size container of Cool Whip. Mix thoroughly with hand mixer. Pour over Oreo cookie crust. Sprinkle with remaining Oreo cookie crumbs. Refrigerate several hours before serving. Randy Rigg
