Bake the chocolate cake according to the boxed directions if using a boxed cake mix, if making a homemade cake you can use my favorite chocolate cake recipe or your favorite. Once the cake is baked let the chocolate cake cool completely.

Cut the cake into bite sized pieces.

While the cake is cooling make the pudding. If you are using homemade pudding make sure that it is cooled completely.

Crush the Oreo Cookies. The easiest way I have found is to put them in a zip close freezer bag and use a rolling pin to crush them.

In a trifle dish or a large clear bowl, put half of the chocolate cake in a layer on the bottom. Then a layer using half of the pudding, then half of the Oreos and half of the cool whip.

Layer everything again in the same order.

After the second layer of cool whip top with chocolate shreds and full Oreo Cookies.
