How to Make Peanut Butter Stuffed Brownies Recipe
Step 1: Prepare the Chocolate Ganache
Start by bringing ¼ cup of heavy whipping cream to a slow simmer over low heat—don’t let it boil! Pour this warm cream over ½ cup of semi-sweet chocolate chips in a heat-proof bowl. Whisk gently until you achieve a smooth, glossy ganache. Then, fold in ½ cup of creamy peanut butter to give it that irresistible swirl of nutty goodness. Set it aside to cool while you prepare the brownies.
Step 2: Mix the Brownie Batter
In a large bowl, combine the melted butter and sugar. Beat in the eggs one at a time, then stir in vanilla extract. Add the melted semi-sweet chocolate chips, mixing until smooth and shiny. In a separate bowl, sift together the flour, cocoa powder, and kosher salt. Gradually fold the dry ingredients into the wet, being careful not to overmix—you want those brownies dense and fudgy. Stir in the peanut butter chips to scatter little bursts of peanut flavor throughout.
Step 3: Prepare the Peanut Butter Filling
Using a mixer, blend the softened butter, both creamy and chunky peanut butter, powdered sugar, and 2 tablespoons of heavy whipping cream. The result should be a thick but spreadable peanut butter frosting that forms the gooey center of your brownies.
Step 4: Assemble the Peanut Butter Stuffed Brownies
Line a 9×13-inch baking pan with parchment paper and pour half of the brownie batter evenly into the pan. Dollop the peanut butter filling across the batter, then gently spread it out but don’t reach the edges, leaving a little margin to avoid mixing layers. Finally, pour the remaining brownie batter on top, smoothing it to cover the filling completely.
Step 5: Bake to Perfection
Bake the brownies at 350°F (175°C) for about 40 minutes or until a toothpick inserted near the edges comes out clean. The center should still be slightly fudgy—remember, that’s the magic of these stuffed brownies! Allow them to cool before topping with the peanut butter chocolate ganache you prepared earlier.
How to Serve Peanut Butter Stuffed Brownies Recipe

Garnishes
A dusting of powdered sugar or a few crunchy roasted peanuts sprinkled on top take these brownies from decadent to downright show-stopping. A drizzle of melted chocolate or a little flaky sea salt can also add an elegant touch and enhance the flavor layers.
Side Dishes
These brownies are rich, so pairing them with a scoop of vanilla ice cream or a dollop of whipped cream helps balance the intensity. A fresh berry compote or sliced strawberries add a bright, tangy contrast that keeps your palate excited.
Creative Ways to Present
Serve individual brownies in cute ramekins with a spoon for a cozy, indulgent treat. You can also cut them into smaller bite-sized squares and stick in a toothpick for fun party snacks. Wrapping a brownie square with a colorful ribbon makes for a lovely gift that friends and family will adore.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Peanut Butter Stuffed Brownies Recipe wrapped tightly in plastic wrap or stored in an airtight container at room temperature for up to three days. If your kitchen is warm, storing them in the fridge will keep them fresh and prevent the peanut butter filling from becoming too soft.
Freezing
These brownies freeze beautifully. Wrap individual slices tightly in plastic wrap and place them in a freezer-safe container or bag. They will keep well for up to three months and thaw quickly at room temperature or in the fridge overnight.
Reheating
To enjoy them warm, microwave a brownie for about 15 seconds or pop it in a preheated oven at 300°F (150°C) for 5–7 minutes. The peanut butter filling will get wonderfully gooey again, making each bite extra indulgent.
FAQs
Can I use natural peanut butter instead of creamy and chunky peanut butter?
You can certainly use natural peanut butter, but keep in mind it may alter the texture of the filling slightly since natural peanut butter is thinner and less sweet. Adding a bit more powdered sugar can help maintain that classic creamy, sweet filling.
What pan size is best for this Peanut Butter Stuffed Brownies Recipe?
A 9×13 inch pan is ideal because it allows the brownies to bake evenly and gives a perfect thickness that showcases the peanut butter stuffing without overwhelming the chocolate layers.
Can I make these brownies gluten-free?
Absolutely, you can substitute the flour with a gluten-free all-purpose flour blend. Just check that your cocoa powder and chips are gluten-free as well. The texture may be a touch different, but the flavor will still shine!
Is it necessary to melt the chocolate chips for the batter?
Melting the chocolate chips helps create a silky, fudgy batter with that signature dense texture. If you use unmelted chips, they will add pockets of texture but might impact the overall smoothness of the brownies.
How long should I wait before slicing the brownies?
It’s best to let the brownies cool completely in the pan for at least an hour. This allows the peanut butter filling to set and makes cutting clean slices much easier—plus, no one wants a gooey mess when they’re ready to enjoy!
