Creating Your Own Costco Peanut Butter Pie Recipe

Good news! You don’t have to endure the long checkout line or the lack of free samples at your local Costco to enjoy this sweet treat. With a bit of patience and some basic baking skills, you can create your own Costco style peanut butter pie. Let’s start with the first thing – the crust.

The Buttery Graham Cracker Crumble Crust

For the crust, you’ll need graham crackers and some butter. The goal here is to create a buttery graham cracker crust that holds the pie together while adding a touch of sweetness. This crust plays a dual role by being the base and playing off the rich flavors of the rest of the filling.

The Creamy Peanut Butter Filling

Next, you’ll prepare the creamy peanut butter filling. This is where that delicious peanut butter flavor comes into play. With cream cheese, powdered sugar, and a good amount of peanut butter, this layer is the heart of the Costco peanut butter pie recipe.

The Chocolate Mousse Layer

After the peanut butter layer comes the chocolate mousse layer. This layer, made with chocolate chips, cream, and just enough gelatin, complements the peanut butter layer perfectly. It’s a creamy, decadent, and rich layer that takes the pie to the next level.

The Finishing Touches

Finally, the whipped cream layer is piped on top, followed by a scattering of mini marshmallows and a drizzling of reserved peanut butter. The result? A perfect copycat recipe of the Costco peanut butter pie, ready to impress your guests and satisfy your cravings.

Cook Time: 4 hours 30 minutes

This is a homemade version of the much-loved Costco Peanut Butter Pie. It is a rich, creamy, and utterly delicious dessert perfect for special occasions or just when you're in the mood for something sweet and satisfying.



  • 2 cups chocolate sandwich cookie crumbs
  • 6 tablespoons unsalted butter, melted


  • 1 cup creamy peanut butter
  • 1 cup powdered sugar
  • 1 (8 ounce) package cream cheese, softened
  • 1/4 cup milk
  • 1 teaspoon pure vanilla extract
  • 1 (8 ounce) tub frozen whipped topping, thawed


  • 1 cup semi-sweet chocolate chips
  • 1/2 cup heavy cream
  • 2 tablespoons unsalted butter
  • 1/4 cup chopped peanuts


  1. Start by making the crust. Mix the chocolate cookie crumbs and melted butter together in a medium bowl until well combined. Transfer the mixture into a 9-inch pie dish and press it evenly onto the bottom and up the sides. Place the crust in the refrigerator to set while you prepare the filling.
  2. For the filling, beat the peanut butter, powdered sugar, cream cheese, milk, and vanilla extract together in a large bowl until smooth and creamy.
  3. Fold in the whipped topping until fully incorporated. Pour the filling into the chilled crust and spread it out evenly.
  4. Place the pie in the freezer for about 4 hours, or until it's firm.
  5. When the pie is almost set, prepare the topping. Place the chocolate chips, heavy cream, and butter in a small saucepan over low heat. Stir the mixture until the chocolate is fully melted and smooth.
  6. Remove the pie from the freezer and pour the chocolate topping over it, carefully spreading it out evenly. Sprinkle the chopped peanuts on top, if using.
  7. Place the pie back into the freezer for another 30 minutes, or until the chocolate topping is set.
  8. Before serving, allow the pie to sit at room temperature for about 10 minutes to make cutting easier.


This pie can be stored in the fridge for up to 5 days or in the freezer for up to 2 months. If frozen, let it thaw in the fridge before serving.
