Put your vanilla pudding into a mixing bowl. Add 1.5 cups of cold milk, and then use a hand mixer and mix for 2-3 minutes until the pudding thickens.
Take 6-7 oreos and crush them in a baggie. Pour into the pudding and stir in.
Fold the whipped cream or cool whip into your pudding mixture.
Scoop into a serving dish and top with remaining oreos, broken into large chunks.
This can be eaten right away, or put in the fridge and held until you need it. Either way, its delicious!
