Peanut Butter Oreo Dessert

If you are a peanut butter dessert lover like me, this one is hands down one of my favorites.  The thick Oreo crust is the perfect complement to peanut butter.  And, we definitely introduce peanut butter in this dessert, and in a few different amazing ways! For another lavish, layered, and decadent Oreo crust dessert, be sure to try my Chocolate Mud Bars!

Ingredients & Substitutions

Crust: The crust is a simple mixture of crushed Oreo Cookies and butter. The consistency of the cookie crumbles is important, so I would recommend using a food processor to ensure that you can get the finest grain.  For this dessert, I left the white cream filling in the Oreo during the food processing step. You could also use a store-bought cookie crust.

Peanut Butter Filling: For the peanut butter filling, start by creaming the cream cheese to make it light and fluffy, and then add in the peanut butter, whipped cream, and confectioners’ sugar.  Pour that on top of the Oreo Crust.  Next, chop up some peanut butter cups, or buy the mini peanut butter cups and just use those (which is what I did).

Chocolate Mousse: You will have some chocolate mousse leftover. Simply save it to serve as a dessert or enjoy the chocolate treat yourself!

Can I Use a Different Pan?

You can use a different-sized pan, but it will change the height of the layers. For instance, if you use an 8×8-inch pan, it will be very, very thick and will overflow. If you use a 9×13-inch pan the layers will be thinner.

  1. The Peanut Butter Oreo Dessert was so easy to make and really quite delicious…and I’m not a peanut butter lover

    thank you for the recipe

  2. We have a peanut/tree nut allergy in the family so what could I substitute for the peanut butter?

    This sounds absolutely delicious!

  3. Ommg!!! I have found my recipe when I need a chocolate fix!!! It’s rich, creamy, yet light and fluffy. Thank you I am baker!!!

  4. Can you confirm that 8 oz of cool whip is supposed to go into both the cream cheese layer andthe chocolate layer and not 8oz split between the 2? My cream cheese layer does not have the same look as yours.
