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.  Boy oh boy do we introduce peanut butter in this dessert.  In a few different amazing ways!

How to Make this Peanut Butter Dessert

Since this is a no-bake Peanut Butter Dessert the steps are relatively simple.  I’ll break each one down for you.

Oreo 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.

The Key to the Perfect Crust

Since this is a no-bake Oreo crust, just a few small tips on how to get it right the first time.  Butter and pressure. Make sure that all of the Oreo crumbles are completely covered in butter.  The butter helps them solidify and stick together.  Proper pressure, such as when you use a glass to press down, ensures an even, level crust.

The BEST Peanut Butter Dessert

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 powdered sugar.  Pour that on top of the Oreo Crust.  Next, chop up some peanut butter cup candy and make another on top.  Or, you can buy the mini peanut butter cups and just use those (which is what I did).

Can I Use a Different Size Pan?

You can, 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.
