Ingredients You’ll Need

A white marbled surface holds multiple small white bowls and containers arranged neatly: a bowl filled with light brown crushed graham crackers, a bowl of powdered white sugar, a small bowl of white milk, a small bowl of dark liquid vanilla extract, a square white bowl filled with dark chocolate chips, and a clear glass pitcher with white cream. There is also a stick of butter labeled

To create this dreamy pie, you’ll want some simple, essential ingredients that each play a starring role. From the crisp graham cracker crust that sets the foundation, to the silky peanut butter mousse and the rich chocolate cream layer, every component is crafted to build layers of flavor and texture that sing in harmony.

Graham cracker crumbs (2 1/2 cups): The base of our crust, providing a sweet, slightly crunchy foundation.

Butter (1/2 cup, melted): Acts as a binding agent, adding richness and moisture to the crust.
Sugar (1/2 cup): Sweetens and helps caramelize the crust slightly during baking.
Cream cheese (8 ounces, softened): Brings a tangy creaminess to the peanut butter mousse layer.

Creamy peanut butter (3/4 cup): The star flavor that infuses the mousse with salty sweetness.
Powdered sugar (1 1/4 cups plus 2 tablespoons, sifted): Adds sweetness and helps smooth the texture in both mousse and topping.
Whole milk (2 tablespoons): Lightens the peanut butter filling for a smooth consistency.

Vanilla extract (1 teaspoon): Enhances all the flavors subtly, rounding out the sweetness.
Heavy whipping cream (3 cups total, divided): Whipped to add airy lightness in both the mousse and chocolate layers.
Unflavored gelatin (0.25 ounce package): Essential for setting the chocolate cream layer perfectly.

Water (2 tablespoons): Used to bloom the gelatin for that flawless texture.
Large egg (1): Incorporates richness and helps thicken the chocolate layer.
Granulated sugar (4 tablespoons): Sweetens the chocolate filling delicately.
Unsweetened cocoa powder (1/3 cup): Offers deep chocolate flavor without overwhelming sweetness.

Semi-sweet chocolate chips (1 cup): Melted into the chocolate cream for an indulgent finish.

How to Make Costco Peanut Butter Chocolate Cream Pie Recipe

Step 1: Prepare the Graham Cracker Crust

Start by preheating your oven to 375 degrees Fahrenheit and mixing graham cracker crumbs, melted butter, and sugar until every crumb is moistened, reserving a bit for garnish later. Press this mixture gently but firmly into a deep 9 ½ inch pie plate, scooping it up the sides to create that perfect crust wall. Bake it for a short, magical 6 minutes and then let it cool completely—this crust is the sturdy yet buttery base that holds all the delicious layers on top.

Step 2: Whip Up the Peanut Butter Mousse Layer

Chill your mixing bowl and beaters for 15 minutes to ensure the cream whips up nice and fluffy. Blend softened cream cheese with creamy peanut butter until perfectly smooth, then add sifted powdered sugar, whole milk, and vanilla to create an irresistible peanut butter mousse. Whip heavy cream with a bit of powdered sugar until soft peaks appear, then gently fold it into your peanut butter mixture for a creamy, airy texture. Reserve a portion of this mousse for piping a decorative topping, then pour the rest into your chilled crust and chill for at least 20 minutes to let it set.

Step 3: Create the Chocolate Cream Pie Layer

Bloom your gelatin by sprinkling it over water and letting it sit. Meanwhile, whisk together the egg, milk, sugar, and cocoa in a saucepan, heating gently while stirring until the mixture thickens slightly. Stir in the bloomed gelatin, then melt chocolate chips with a touch of heavy cream. Combine the chocolate mixture with the gelatin base, and fold in whipped heavy cream beaten to stiff peaks. Pour this luscious chocolate cream over the peanut butter mousse, smoothing it out carefully. Don’t forget to save some chocolate filling if you overprepare—you can serve it separately as a decadent mousse treat!

Step 4: Add the Finishing Touches

Pipe the reserved peanut butter mousse around the edges of the pie with a star tip for that bakery-style look, and sprinkle the reserved graham cracker crumbs on top for a bit of added crunch and visual appeal. Finally, pop the pie into the fridge for at least 2 hours to set completely. Patience here will reward you with a perfectly firm yet silky texture that slices beautifully.

The image shows a round pie with three distinct layers, placed on a white marbled surface. The bottom layer is a crumbly golden crust with a slightly rough texture. Above the crust is a smooth, light brown filling that covers the entire pie evenly. The top edge of the pie is decorated with evenly spaced swirls of creamy beige frosting, each swirl thick and textured like soft whipped cream. Around the frosting swirls, there are small crumbs of the same crust, adding a crunchy detail to the edge. Nearby is a white bowl filled with golden crumbs and a spoon inside it, as well as a piping bag filled with the same creamy frosting used on the pie. A white and blue striped cloth is placed in the background. Photo taken with an iphone --ar 4:5 --v 7

Garnishes

Adding garnishes can elevate your pie to showstopper status. Whipped cream rosettes, a dusting of cocoa powder, or chopped peanuts sprinkled over the top offer both texture and a visual feast. For a touch of elegance, drizzle some melted chocolate or even a little caramel sauce around the plate for each slice.

Side Dishes

This pie is rich and indulgent, so it pairs wonderfully with lighter accompaniments. Fresh fruit like sliced strawberries or raspberries can add a pop of acidity to balance the sweetness. A scoop of vanilla or coffee ice cream complements the creamy layers perfectly, creating an indulgent dessert experience.

Creative Ways to Present

If you’re feeling adventurous, serve this pie as individual mousse cups using the leftover chocolate filling. Layer crushed graham crackers in small glasses, add a spoonful of peanut butter mousse, then top with chocolate cream and a dollop of the piped peanut butter topping. It’s a charming way to serve guests and mashup party presentation with minimal effort.

Make Ahead and Storage

Storing Leftovers

This pie deserves a spot in your fridge to maintain its creamy texture and fresh taste. Cover it tightly with plastic wrap or an airtight container to prevent it from absorbing any fridge odors. It will stay delicious and slice-friendly for up to 3 days—if it lasts that long!

Freezing

While freezing this pie is possible, the texture of the mousse layers might be slightly impacted upon thawing. If you decide to freeze it, wrap the pie securely in plastic wrap and foil. Thaw it overnight in the refrigerator before serving for best results, though the freshly made version always tastes best.

Reheating

This chilled pie is best enjoyed cold, so there’s no need to reheat it. Serving it straight from the fridge ensures that each bite remains luscious and perfectly firm. Trying to warm it will cause the delicate layers to melt and lose their charm.

FAQs

Can I use crunchy peanut butter instead of creamy?

For this recipe, creamy peanut butter is key to achieving that smooth, luscious mousse texture. Crunchy peanut butter could disrupt the silky consistency, though you could try it if you prefer a bit of crunch in your filling.

Is gelatin necessary for the chocolate layer?

Yes, gelatin helps the chocolate cream layer set nicely and maintain a sliceable, mousse-like consistency. Without gelatin, the filling may be too soft and not hold its structure well.

Can I make this pie ahead of time?

Absolutely! In fact, making it a day in advance is ideal as it allows all the layers to set perfectly and flavors to meld. Just keep it refrigerated and covered.

How can I reduce the sweetness of the peanut butter layer?

If you want a less sweet pie, reduce the powdered sugar in the peanut butter mousse by about 1/4 cup. The original recipe matches Costco’s sweetness closely, but that tweak can help if you prefer a milder taste.

What’s the best way to slice this pie?

Use a sharp, clean knife chilled briefly in hot water before slicing. Wipe the knife between cuts to get neat slices with clean layers visible—no messy edges here!
