Costco Peanut Butter Chocolate Cream Pie Recipe

We spent a week trying to get our hands on one of these popular 5-pound pies (5 POUNDS!) with no success. Finally my bestie came in clutch and showed up on my doorstep with one in hand. I couldn’t wait to dive in and try it! I admit, it was worth the hype. We took to Instagram and asked if you wanted us to copycat this recipe and the response was overwhelming. Our readers have spoken! You wanted the copycat recipe and we delivered. We present to you… Costco Peanut Butter Chocolate Cream Pie.

What’s The Deal With Costco’s Peanut Butter Chocolate Cream Pie?

Before we get into the recipe, some of you may be wondering what all the hype is with this pie. It seemed to come out of nowhere! In March 2023, Costco released this cream pie and it instantly became a huge hit with Costco shoppers. It weighs in at over four and a half pounds and can serve up to 16 people. Laura Lamb (@CostcoHotFinds) posted a video on TikTok of this decadent pie and it immediately went viral with millions of views. Since posting this video, most Costco warehouses can hardly keep it on the shelves. In fact, it often sells out before the bakers can take it from the bakery trolley to the refrigerated shelf! It took us a week to finally get our hands on one and it was totally worth it.

Costco Chocolate Peanut Butter Pie Ingredients

It may seem like this recipe uses a lot of ingredients, but a lot of ingredients are duplicated between the two cream pie layers. All of the ingredients are also very basic. You should easily be able to find them all at most grocery stores.

Graham Cracker Crust

Graham crackers Sugar Butter

Peanut Butter Mousse (and Topping)

Cream cheese Peanut butter Powdered sugar Milk Vanilla extract Heavy whipping cream

Chocolate Cream Pie Filling

Butter Gelatin (I like to use the Knox brand. You will need the .25 ounce package. ) Egg Milk Sugar Unsweetened cocoa powder Semi-sweet chocolate chips Heavy whipping cream

Make It Your Own

Even though this pie is wildly delicious on its own, we came up with a few ideas that we thought would take it to the next level. Here are some fun variations:

Reese’s Peanut Butter Cups – Chop up some Reese’s cups and sprinkle them over the top Oreo Pie Crust – Swap out the graham cracker crust for a crust made from Oreos Reese’s Pieces – Sprinkle a few Reese’s pieces over the top for a little added crunch and a pop of color Chocolate Graham Cracker Crust – Swap out the regular graham crackers for chocolate ones

Tips for Making Costco Peanut Butter Chocolate Pie

Crush graham crackers for the crust using a Ziplock bag and a rolling pin or by using a large food processor. If you don’t have an electric mixer with a whisk attachment to whip the fillings, you can use a hand mixer instead. Don’t rush the process! Give each layer some time to set before serving. Allow the completed pie to set in the refrigerator for at least 2 hours. Costco, themselves, told us to allow the filling to cool to 40 degrees before serving.

Storing This Chocolate Peanut Butter Pie

This peanut butter chocolate pie needs to be placed in the refrigerator when storing. It is best to lightly wrap the pie with plastic wrap or use an air tight container that does not touch the topping. Place in the fridge for 5 to 7 days or in the freezer for 1 month. When ready to enjoy the frozen pie, let thaw in the refrigerator overnight. Read Next: 25+ Thanksgiving Pie Recipes
