Step 1

Start by spraying your cake pan with non-stick cooking spray. Or if you want, you can grease it with butter for extra tastiness!

Step 2

Then, place a layer of whole Oreo cookies evenly on the bottom of the baking dish.

Step 3

Next, pour the sweetened condensed milk over the top of the cookies.

Step 4

In a separate bowl, mix together the marshmallow cream and the cool whip until well combined.

Step 5

After that, sprinkle the dry chocolate cake mix over the cream to cover the entire surface of the baking pan.

Step 6

Then, slice the butter into little pats and place them evenly over the top of the cake. I like to make mine thin enough to cover the entire surface of the cake.

Step 7

Place the cake pan in the oven and bake for 1 hour at 350F, the top should be bubbling by the end of baking.

Step 8

Top your cake with Oreo cookie crumbs and some melted cookies & creme wafers. Slice, serve & enjoy!
