This Oreo peanut butter pie combines the irresistible flavors of creamy peanut butter and chocolate cookies into one decadent dessert. The crunchy Oreo crust cradles a silky smooth peanut butter filling that will satisfy any sweet tooth craving. I perfected this recipe after years of family gatherings where it consistently disappears within minutes of hitting the table.
This pie has become my signature dessert at neighborhood block parties. The first time I brought it to our summer cookout, three neighbors asked for the recipe before the night was over. Now I always bring two pies because one simply isn't enough.
Ingredients
- Oreo cookies: the chocolate cookies create the perfect crunchy foundation with their distinctive cocoa flavor
- Unsalted butter: binds the crust together and adds richness. Always use unsalted to control the salt level
- Granulated sugar: enhances the sweetness of the crust and helps it hold together
- Cream cheese: provides tanginess to balance the sweetness. Be sure to use full fat for the best texture
- Creamy peanut butter: the star of the show. Choose a quality brand like Jif or Skippy for consistent results
- Powdered sugar: sweetens while dissolving completely into the filling for a smooth texture
- Whipped topping: creates the light airy texture that makes this pie irresistible. Let it thaw completely
- Vanilla extract: adds depth of flavor. Pure vanilla extract gives the best results
Step by Step Instructions
- Prepare the Oreo crust:
- Process Oreos in a food processor until they become fine crumbs. The texture should be like wet sand with no large pieces remaining. Mix thoroughly with melted butter, sugar, and salt until every crumb is moistened. Press firmly into a pie dish using the bottom of a measuring cup to create an even layer. Bake at 350°F for exactly 10 minutes until just set.
- Create the peanut butter filling:
- Beat softened cream cheese and peanut butter together until completely smooth and no streaks remain. This usually takes about 2 minutes with an electric mixer. The mixture should be fluffy and light in color. Add powdered sugar gradually while mixing at low speed to prevent a sugar cloud. Once incorporated, increase speed and beat until silky.
- Fold in the whipped topping:
- Gently fold the thawed whipped topping and vanilla into the peanut butter mixture using a rubber spatula. Use a light hand and fold from the bottom up to maintain as much air as possible. The filling should be light but stable, with an even color throughout.
- Assemble and chill:
- Spread the filling into the cooled crust, creating decorative swirls on top if desired. Chill in the freezer for at least one hour to set completely. For the best texture, remove from the freezer about 10 minutes before serving to slightly soften.

The secret to this pie is using room temperature cream cheese. The first time I made it with cold cream cheese, I ended up with tiny lumps throughout the filling. Now I always set the cream cheese out at least an hour before starting. My husband says the combination of creamy filling and crunchy crust reminds him of the peanut butter and Oreo sandwiches his mom would make him as an after school treat.
Make It Your Own
This pie welcomes customization based on your preferences. For chocolate lovers, drizzle melted chocolate over the top just before serving. A sprinkle of sea salt adds a sophisticated touch that enhances the peanut butter flavor. You can also fold chopped Reese's cups directly into the filling for pockets of chocolate peanut butter goodness throughout.
Storage Tips
This pie keeps beautifully in the refrigerator for up to 5 days, though the crust will soften slightly over time. For longer storage, keep it in the freezer for up to one month. Wrap individual slices in plastic wrap for quick dessert emergencies. If frozen solid, allow slices to thaw for about 20 minutes at room temperature before enjoying.
Serving Suggestions
While this pie is perfect on its own, it reaches new heights with thoughtful accompaniments. Serve with a scoop of vanilla ice cream for a temperature contrast, or add a dollop of freshly whipped cream and chocolate shavings for visual appeal. For an extra indulgent presentation, warm some hot fudge sauce to drizzle over each slice just before serving.
