When it comes to peanut butter desserts, this Peanut Butter Oreo Dessert will top them all. This delectable treat has layers of velvety peanut butter filling, peanut butter-filled chocolate candy, and a rich hot fudge mousse piled on top of an Oreo cookie crust. To top it all off, there is no baking involved! If you love no-bake desserts, make sure to check out my piggy pie dessert and my no-bake cheesecake!
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.
How to Store Peanut Butter Oreo Dessert
This dessert should be kept covered and refrigerated. It should last 5-6 days in the refrigerator.

So good! Made two smaller pans so I could share one with my supervisor for Bosses’ Day. I couldn’t wait for ours to set up all the way to taste-test, but it is fantastic! Forgot to put in peanut butter cups, but it was still delicious and will go in the dessert rotation.
