I love this Costco Chocolate Peanut Butter Pie because it combines several delicious textures in one dessert. The chocolate cookie crust adds a crunchy base, the peanut butter filling is smooth and fluffy, and the chocolate layer gives every slice a rich finish.
I also appreciate that this recipe doesn’t require baking. I can prepare the crust and fillings with a few simple ingredients, assemble the pie, and let the refrigerator do most of the remaining work.
Another reason I enjoy making this pie is that I can prepare it ahead of time. I find that chilling overnight helps the layers become firm and makes the pie easier to slice. I also love how impressive it looks with a little whipped cream, chocolate drizzle, or chopped peanut butter cups on top.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For this homemade version, I use:
-
Chocolate sandwich cookies
-
Unsalted butter
-
Cream cheese, softened
-
Creamy peanut butter
-
Powdered sugar
-
Vanilla extract
-
Heavy whipping cream
-
Semisweet chocolate
-
Milk chocolate, optional
-
Salt
-
Whipped cream, optional
-
Chopped peanut butter cups, optional
-
Chocolate shavings, optional
I prefer using regular creamy peanut butter because it creates a smooth, stable filling. I also like using chocolate sandwich cookies for the crust since their cocoa flavor balances the sweetness of the peanut butter cream.
Directions
I start by preparing a 9-inch deep-dish pie pan or springform pan. I lightly grease the pan if needed and set it aside while making the crust.
Next, I place the chocolate sandwich cookies in a food processor and blend them into fine crumbs. I add the melted butter and pulse until the crumbs resemble damp sand.
I transfer the cookie mixture to the prepared pan and press it firmly across the bottom and up the sides. I use the bottom of a measuring cup to create an even, compact crust.
I refrigerate the crust for approximately 20 minutes while preparing the filling.
In a large mixing bowl, I beat the softened cream cheese with an electric mixer until smooth and creamy. I scrape down the sides of the bowl to remove any lumps.
Next, I add the creamy peanut butter, powdered sugar, vanilla extract, and a small pinch of salt. I continue mixing until the filling becomes thick, smooth, and evenly combined.
In a separate chilled bowl, I whip the heavy cream until stiff peaks form. I make sure not to overwhip it because I want a light, fluffy texture.
I gently fold the whipped cream into the peanut butter mixture in several additions. I use a spatula and slow folding motions to keep as much air in the filling as possible.
Once the peanut butter filling is smooth and fluffy, I spoon it into the chilled chocolate crust. I spread it evenly with an offset spatula, leaving enough space for the chocolate topping.
I place the pie in the refrigerator while preparing the chocolate layer.
For the chocolate topping, I finely chop the semisweet chocolate and place it in a heatproof bowl.
I warm additional heavy cream in a small saucepan until it is steaming but not boiling. I pour the warm cream over the chopped chocolate and let it sit for approximately 2 minutes.
I gently stir until the chocolate melts completely and the mixture becomes smooth and glossy. I let the ganache cool until it is no longer hot but remains pourable.
Next, I slowly pour the chocolate ganache over the peanut butter filling. I spread it carefully into an even layer without pressing into the cream underneath.
I cover the pie loosely and refrigerate it for at least 6 hours, although I prefer chilling it overnight for the cleanest slices.
Once the pie is fully set, I decorate it with whipped cream, chopped peanut butter cups, or chocolate shavings when I want a more elaborate presentation.
I slice the pie with a sharp knife, wiping the blade clean between cuts. I like letting each slice sit at room temperature for approximately 5 minutes before serving so the filling softens slightly.
Servings and Timing
I usually get about 10 to 12 generous slices from one deep-dish pie.
-
Prep time: 30 minutes

Chill time: At least 6 hours
-
Total time: About 6 hours 35 minutes
-
Servings: 10–12 slices
Variations
For an Extra Chocolate Peanut Butter Pie, I add a thin layer of chocolate ganache directly over the cookie crust before adding the peanut butter filling. I love how this creates an additional chocolate layer in every slice.
When I want a lighter chocolate flavor, I use milk chocolate instead of semisweet chocolate for the topping. I find that it creates a sweeter, creamier finish that pairs beautifully with the peanut butter.
For a Crunchy Peanut Butter Pie, I fold finely chopped roasted peanuts into part of the filling. I enjoy the extra texture, although I keep the pieces small so the pie remains easy to slice.
I sometimes add chopped peanut butter cups between the crust and filling. I love discovering little pieces of chocolate and peanut butter throughout the pie.
For a Salted Chocolate version, I sprinkle a small amount of flaky sea salt over the ganache before it sets. I find that the salt balances the sweetness and enhances the chocolate flavor.
When I want individual desserts, I divide the cookie crumbs, peanut butter filling, and chocolate ganache among small dessert cups. I enjoy serving these mini versions at parties because they don’t require slicing.
Storage/Reheating
I keep leftover Chocolate Peanut Butter Pie covered in the refrigerator because the filling contains cream cheese and whipped cream. I store it for up to 3 to 4 days.
I prefer keeping the pie in its original pan with a fitted cover or loosely placed plastic wrap. I avoid pressing the wrap directly against the chocolate topping.
For longer storage, I freeze individual slices on a parchment-lined tray until firm. I then wrap each slice securely and place it in a freezer-safe container for up to 2 months.
When I want to serve frozen pie, I thaw the slices in the refrigerator for several hours. I find that slow thawing helps preserve the creamy texture.
I don’t reheat this dessert because it is meant to be served chilled. I usually remove a slice from the refrigerator a few minutes before eating so the peanut butter filling becomes slightly softer.
FAQs
Is this the exact Costco Chocolate Peanut Butter Pie recipe?
No. I make this as a homemade copycat inspired by Costco’s chocolate peanut butter pie. I use a chocolate cookie crust, fluffy peanut butter cream, and chocolate ganache to recreate its rich, layered dessert experience, but I don’t claim it is Costco’s proprietary recipe.
Can I make this pie without baking?
Yes. I make the entire pie without using an oven. I chill the chocolate cookie crust instead of baking it, and I prepare the filling and ganache separately before refrigerating the assembled pie until firm.
Why is my peanut butter pie filling too soft?
I find that the filling can become too soft when the cream isn’t whipped firmly enough or the pie hasn’t chilled long enough. I use softened cream cheese rather than melted cream cheese, whip the cream to stiff peaks, and refrigerate the assembled pie for at least 6 hours.
Can I use natural peanut butter?
I prefer regular creamy peanut butter because it has a more consistent texture and blends smoothly with the cream cheese. Natural peanut butter can separate or make the filling softer, especially when it contains a lot of free oil.
Can I make Costco-style Chocolate Peanut Butter Pie ahead of time?
Absolutely. I prefer preparing this pie the day before serving. I find that an overnight chill helps the layers set and makes slicing easier. I usually add decorative whipped cream or chopped peanut butter cups shortly before serving.
Conclusion
I love making this Costco-inspired Chocolate Peanut Butter Pie when I want a rich, impressive dessert without turning on the oven. Its crunchy chocolate crust, fluffy peanut butter filling, and smooth ganache make every chilled slice a delicious treat.
