Butter binds the cookie crust together while also creating a rich, fudgy brownie layer.
Semi-Sweet Baking Chocolate
Provides deep chocolate flavor and creates the dense, brownie-like texture.
All-Purpose Flour
A small amount of flour gives the brownie filling just enough structure while keeping it soft and fudgy.
Granulated Sugar
Adds sweetness and helps create the signature shiny brownie top.
Vanilla Extract
Enhances both the chocolate and peanut butter flavors.
Salt
Balances the sweetness and intensifies the chocolate flavor.
Eggs and Egg White
Provide structure while keeping the brownie filling moist and rich.
White Chocolate
Melts into the topping to create a smooth, creamy texture with a hint of sweetness.
Heavy Whipping Cream
Creates a silky ganache-like topping that spreads beautifully.
Creamy Peanut Butter
Regular creamy peanut butter delivers the best smooth texture and rich peanut butter flavor.

How to Make Peanut Butter Brownie Pie
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C).
Step 2: Make the Oreo Crust
Place the Oreo cookies into a food processor and pulse until they become fine crumbs.
Reserve 2 tablespoons of the crumbs for garnish.
Mix the remaining crumbs with the melted butter until evenly coated.
Press the mixture firmly into the bottom and up the sides of a 9-inch or 10-inch springform pan.
Refrigerate while preparing the filling.
Step 3: Make the Brownie Filling
Place the butter and chopped semi-sweet chocolate into a microwave-safe bowl.
Microwave in 30-second intervals, stirring after each, until completely melted and smooth.
Whisk in the flour, sugar, vanilla extract, and salt.
Add the eggs and egg white one at a time, whisking until smooth after each addition.
Pour the brownie batter into the prepared Oreo crust.
Step 4: Bake
Place the springform pan on a baking sheet to catch any possible leaks.
Bake for 35 to 45 minutes, or until the center is set and the top is puffed.
Remove from the oven and let cool for 1 hour.
The center will sink slightly as it cools, which is completely normal.
Step 5: Prepare the Peanut Butter Topping
Place the white chocolate and heavy cream into a microwave-safe bowl.
Heat for 1 minute, then whisk until smooth.
Add the creamy peanut butter and stir until silky and fully combined.
Step 6: Finish the Pie
Spread the peanut butter topping evenly over the cooled brownie layer.
Sprinkle with the reserved Oreo crumbs.
Allow the pie to set overnight at room temperature or refrigerate until firm.
Step 7: Serve
For the softest, gooiest texture, allow the pie to come to room temperature before slicing and serving.
Pro Tips & Cooking Secrets
- Don’t overbake the brownie layer—it should be just set in the center for the fudgiest texture.
- Use regular creamy peanut butter instead of natural peanut butter for a smooth, stable topping.
- Let the brownie cool completely before adding the peanut butter topping to prevent melting.
- Run a warm knife around the edge of the springform pan before releasing it for clean presentation.
Serving Suggestions
- Serve with vanilla ice cream or whipped cream.
- Drizzle with warm chocolate or caramel sauce.
- Garnish with chopped peanut butter cups or chocolate curls.
- Pair with hot coffee, espresso, or a cold glass of milk.
How to Store Peanut Butter Brownie Pie
Refrigerator
Store the pie covered in the refrigerator for up to 5 days.
Freezer
Wrap individual slices tightly and freeze for up to 3 months.
Reheating
No reheating is necessary. Let refrigerated slices sit at room temperature for 20 to 30 minutes before serving for the best texture.
Make Ahead
This pie is an excellent make-ahead dessert and actually tastes even better after resting overnight.
Peanut Butter Brownie Pie FAQs
Can I make Peanut Butter Brownie Pie ahead of time?
Yes! In fact, it’s even better after chilling or resting overnight because the flavors have time to develop.
Can I use milk chocolate instead of semi-sweet chocolate?
Yes, but the pie will be noticeably sweeter. Semi-sweet chocolate provides the best balance.
Can I freeze Peanut Butter Brownie Pie?
Absolutely. Wrap slices individually and freeze for up to 3 months. Thaw overnight in the refrigerator before serving.
Why did the brownie layer sink?
That’s completely normal. Brownie pies naturally puff while baking and settle slightly as they cool.
Can I use crunchy peanut butter?
Yes. Crunchy peanut butter works well if you’d like extra texture in the topping.
