Ingredients for Oreo Peanut Butter Cup Pie

All you need is 6 ingredients to make this peanut butter & chocolate freezer pie. This pie is great for anyone that loves cheesecake, peanut butter, chocolate, and especially Reese's peanut butter cups. It takes all the yummy stuff from any of those great desserts into one perfect recipe.

My version of this old-fashioned peanut butter freezer pie is a little less sweet than other recipes. The pie is made with more peanut butter than other recipes plus the powdered sugar is reduced. I find the pie is very sweet even with this adjustment. By using the dark chocolate mini peanut butter cups, the touch of bitterness in the dark chocolate helps add a bit of balance that I find ideal.

Frozen Peanut Butter Cup Pie ingredients

Peanut Butter - use your favorite brand but do NOT use natural peanut butter
Cream Cheese - full-fat is best
Powdered Sugar - confectioner's sugar adds sweetness & keeps it smooth
Cool Whip - adds lightness to it so it is not too dense
Ready-made Oreo Chocolate Pie Crust - the perfect chocolate base for the peanut butter filling
Reese's Peanut Butter Cups - the must-have topping

See the recipe card for amounts and step-by-step instructions.

How to Make Frozen Oreo Peanut Butter Cup Pie

This recipe is super easy - like 1-2-3 quick. Here are the simple steps to make this no-bake peanut butter & chocolate pie in an Oreo cookie crust.

Mix the Peanut Butter Cream Cheese Filling

In a medium-sized mixing bowl add peanut butter and softened cream cheese. Mix thoroughly on medium with a hand mixer. Scrape the bowl with a rubber spatula as needed to ensure all is combined completely

Add powdered sugar and on low, mix with a hand mixer. Scrape the bowl with a rubber spatula as needed.

Fold in the Cool Whip

With the rubber spatula, fold gently the thawed Cool Whip into the mixture. Combine until the mixture is smooth and completely incorporated together. There should not be any peanut butter lumps or sections of just Cool Whip.

It does take a bit to get this folded in. Be patient, it is worth the effort. Folding ensures the pie is not dense but smooth & light even for a freezer pie.

Once it is mixed well, time to get it in the pie crust. Remove the clear cover from the ready-made crust. Pour the mixture into the cookie crust and smooth it out so the filling is evenly distributed.

How Long to Freeze the Oreo Pie?

Once the pie is assembled, it is ready to go in the freezer. This no-bake pie is so easy. The hardest part is waiting for it to set and be ready for slicing.

Begin by sealing up the pie so it is freezer ready. Flip the clear lid so that it is a mound over the pie and press the foil edges over the lid to seal it back over the pie. Freeze pie for at least 2 hours before serving

Serve the Frozen Oreo Peanut Butter Cup Pie

About 10 minutes before serving, remove the pie from the freezer to bring it to room temperature. This will ensure it is easy to slice.

Remove the clear dome cover and using a pie cutter, slice 8 equal-sized pieces, and place them on dessert plates. Top with peanut butter cups that have been cut into ¼ or ½ pieces.

Variations & Substitutes

This pie is so simple with just a few ingredients to ensure it tastes just like Reese's peanut butter cup. It is amazing as written. However, if you need to make a change due to dietary needs or what you have on hand, here are a few alternate ingredients & recipe changes you can make.

Oreo Cookie Pie Crust - you can use a graham cracker crust instead.
Deluxe - drizzle on hot fudge along with the chopped candy for a slice of pie that is crazy good.
Reese's Pieces - Fold in 1 cup of Reese's Pieces into the peanut butter filling.

For a gluten-free version of this peanut butter pie, you can change out the crust very easily. Oreo makes gluten-free cookies to make your own crust. I also make this without a crust. It slices just fine for a grain-free version. The rest of the ingredients are gluten-free.

Storage

This freezer pie stays in the freezer when not serving. Keep the lid on it and it will last for up to 3 months if never sliced. Once it is sliced, the air exposure will speed up the quality of the pie.

Sliced peanut butter cup pie with chocolate will last in the freezer for up to a month. But it is best enjoyed within 7 days of slicing.

Do not store it in the refrigerator. The contents of the filling will make the crust soggy.
