Blend the Oreo crumbs with melted butter. Press the mixture firmly into a 9x13 baking dish to create the crust layer.
Put it in the freezer to set. About 15-20 minutes should be enough.
While the crust is in the freezer, get a mixing bowl. Whisk the cream cheese, powdered sugar and peanut butter together.
Blend until the mix is smooth. Fold in half of the whipped topping and blend it in. Set the other half of the topping aside.
In another bowl, mix the chocolate pudding and cold milk. Stir until it thickens a little.
Get the crust from the freezer.
First, spread the mixture of peanut butter and cream cheese evenly.
Next, get the pudding bowl and pour it on top of the previous layer. Finish off by spreading the other half of the whipped topping.
Sprinkle the chopped Reese’s Peanut Butter Cups on top. Drizzle the dessert with warmed peanut butter and chocolate fudge sauce.
Put everything in the fridge to chill for 4-5 hours. This gives time for all the layers (and flavors) to blend together.
Once the dessert has had a chance to set, slice, serve and enjoy!
