This homemade peanut butter chocolate cream pie is a copycat of the viral Costco version—only better. Rich, creamy, and satisfying, it layers a crunchy graham cracker crust with a smooth peanut butter filling and a silky chocolate topping swirled with marshmallow crème.

Peanut Butter Chocolate Cream Pie – Viral Costco Copycat

After tasting the oversized, viral Costco peanut butter chocolate cream pie, I wanted to create a homemade version that captures the same indulgent flavors while improving texture and balance. This recipe delivers a satisfying mix of crunchy crust, creamy peanut butter layer, and decadent chocolate topping. It’s straightforward to assemble and makes an impressive dessert for gatherings or a special treat at home.

The pie’s layers come together easily: a pressed graham cracker crust, a whipped peanut butter-cream cheese filling, and a marshmallow-chocolate layer finished with piped peanut butter rosettes and reserved graham crumbs. If you love the chocolate-and-peanut-butter combination, this will become a favorite.

Why This Recipe Works

• The contrast of textures — crunchy crust, dense peanut butter filling, and airy chocolate topping — is exactly what makes this pie special.
• It’s easy to prepare with mostly no-bake steps and common ingredients.
• Chocolate and peanut butter are a classic pairing, and here they’re balanced so neither element overwhelms the other.

Ingredients

Everything you need for one 9-inch pie:

• Graham crackers — crushed for the crust.
• Melted butter — binds the crumbs into a firm crust.
• Granulated sugar — sweetens the crust and whipped cream.
• Marshmallow crème — adds body and sweetness to the chocolate layer.
• Chilled heavy cream — used for whipping into both fillings.
• Semi-sweet chocolate chips — for a smooth chocolate topping (dark chocolate works for extra richness).
• Creamy peanut butter — the base of the peanut butter filling.
• Cream cheese — makes the peanut butter filling silky and stable.
• Confectioners’ sugar — sweetens and thickens the peanut butter filling.
• Vanilla extract — rounds out the peanut butter flavor.

How to Make the Peanut Butter Chocolate Cream Pie

Measurements and the full ingredient list are provided in the recipe card below. Here’s a concise, SEO-friendly overview of the method so you can see how the layers come together.

• Make the crust: Pulse graham crackers into fine crumbs or crush in a bag with a rolling pin. Mix crumbs with melted butter and a bit of sugar. Reserve a small portion of crumbs for garnish. Press the remainder into a 9-inch pie pan and chill in the freezer to firm.
• Prep the chocolate filling: Combine marshmallow crème, 1/4 cup heavy cream, and chocolate chips in a microwave-safe bowl. Microwave in short bursts, stirring until smooth, then let cool until just warm.
• Make the peanut butter filling: Beat peanut butter with softened cream cheese, confectioners’ sugar, and vanilla until silky. Add the remaining chilled cream and beat until just combined. Reserve about 1 cup of this mixture for piping; spread the rest in the chilled crust and return to the freezer while you finish the chocolate layer.
• Finish the chocolate filling: Whip the final cup of chilled heavy cream with granulated sugar to stiff peaks. Fold the whipped cream into the cooled chocolate-marshmallow mixture gently to keep it light. Spread this chocolate topping over the peanut butter layer.
• Garnish and chill: Pipe the reserved peanut butter filling around the pie edge, sprinkle reserved graham crumbs on top, and refrigerate uncovered until fully set — at least 6 hours, preferably overnight.

Recipe Tips

• For a firmer pie, chill for 8–12 hours before serving.
• Use dark chocolate chips for a richer, less-sweet chocolate layer.
• Make sure the cream cheese is fully softened for a lump-free peanut butter filling.
• If using crunchy peanut butter, fold it in at the end to preserve bits of texture.

Storage and Freezing

• Keep leftovers covered in the refrigerator for up to 5 days.
• To freeze, wrap the pie tightly in plastic wrap and foil; freeze up to 2 months. Thaw overnight in the fridge before serving.

Frequently Asked Questions

• Can I use crunchy peanut butter? Yes. Crunchy peanut butter adds texture — fold it in at the end so some crunch remains.
• Can I substitute another nut butter? Almond or hazelnut butter will work, but flavor and texture will change slightly.
• Can I use a different crust? Yes. An Oreo crust is a popular alternative that pairs well with the peanut butter and chocolate layers.
• What toppings work best? Chopped peanuts, extra chocolate chips, or a drizzle of melted chocolate are all great options.
