In a large bowl, place the crushed Oreos and the melted butter. Mix thoroughly until the butter is well incorporated into the crushed Oreos.

After mixing, pour the Oreos and butter mixture into a springform pan, but if you do not have that, you can use a 9 x 13-inch baking pan. This will be your cheesecake base.

Spread the mixture across the pan evenly. Pop the pan into the freezer before you make the filling.

In another large bowl, add the softened cream cheese, cool whip or whipped cream, and powdered sugar. Mix until well combined.

Next, add the filling to the pre-made cheesecake base and spread evenly.

Using the same bowl for the cream cheese mixture, pour the milk and the chocolate pudding and mix well until it thickens. The more you beat it, the more it will thicken.

Add the mixture and spread evenly across the cheesecake.

Pop into the freezer and thaw a bit before serving.
