6-8Oreo cookiesfinely ground (if using the vanilla pudding ONLY)
10Oreo cookiescoarsely broken for topping.
Make up cake as per box directions. Let cool completely once baked.
Poke holes about 1-inch apart on the top of the cake using the handle of a wooden spoon. Avoid making the hole all the way through the cake--about 3/4 way down is good.
Make up the pudding per package directions. If using vanilla pudding, fold in the Oreo crumbs after beating in the milk. Pour across the top of the cake; refrigerate till pudding is set--about 30 minutes.
