First, bake the chocolate cake in a 9 x 13” inch baking dish according to the directions on the back of the package. Let it cool and using the back of a wooden spoon, poke holes into it about and inch and a half apart.
Next, in a medium sized bowl, make the instant pudding by beating it together with the milk. Mix in ½ cup of the peanut butter until it’s evenly combined with the pudding.
Then, spread the pudding mixture over the cake letting it drip into the holes.
Next, microwave the icing for 30- 60 seconds or until it’s melted and pour it over the pudding layer. Carefully spread it out using the back of a spoon so that it’s covering the pudding layer.
Now, place that into the refrigerator to set for about 30 minutes.
Once the icing has set, beat together the cool whip and ½ cup of the peanut butter. Spread that on top of the icing as the third and final layer.
Now, roughly chop the Reese’s peanut butter cups and place them all over the peanut butter cool whip layer. Serve cold and enjoy!
