Delicious Oreo Refrigerator Cake (No-Bake)

This has remained a long time favorite, I have even made this in the winter months and served it to guests many times, lemon flavor pudding mix is also very good to use in place of the chocolate --- you can make this well in advance, it can also be served as a frozen dessert just remove from freezer about 6 minutes before slicing this is just as delicious frozen! if you are serving this at a kid's birthday party place mini Oreo cookies into the topping of Cool Whip facing sideways --- I most always double the chocolate pudding mixture, you may also double the cream cheese mixture if desired --- this is very good!
