Ingredients You’ll Need

This Peanut Butter Stuffed Brownies Recipe uses simple but essential ingredients, each playing a starring role to achieve that perfect balance of richness, moisture, and flavor. From creamy peanut butter to velvety melted chocolate, every item is thoughtfully chosen to deliver the best results.

Creamy conventional peanut butter: Use regular creamy peanut butter—not natural—for an ideal smooth texture that spreads easily and holds together well when frozen.
Unsalted butter: Adds richness and buttery flavor that melts into the chocolate for a fudgy brownie base.
Semisweet baking chocolate: Chopped finely to melt smoothly, giving the brownies deep, luscious chocolate flavor.
Granulated sugar: Sweetens and balances the bitterness of cocoa, helping create that perfect brownie chew.
Large eggs plus 1 egg yolk: Provide structure and moisture while making brownies tender and fudgy.
Vanilla extract: Enhances the overall flavor with warm, inviting notes.
All-purpose flour: Just enough to hold everything together without making the brownies cakey.
Unsweetened cocoa powder: Sifted for smooth incorporation, intensifies the chocolate flavor and adds a rich color.
Fine sea salt: Balances sweetness and brings out deeper chocolate and peanut butter nuances.

How to Make Peanut Butter Stuffed Brownies Recipe

Step 1: Prepare the Peanut Butter Filling

Start by warming your creamy peanut butter in the microwave for about 20 to 30 seconds until it becomes pourable but not piping hot—this makes spreading much easier. Then line an 8-inch square metal pan with parchment paper, spread the peanut butter evenly, and freeze it until firm. This frozen peanut butter layer will later become the delightful surprise inside your brownies, giving them that signature stuffed effect.

Step 2: Create the Brownie Batter

Preheat your oven to 350°F and again line your brownie pan with parchment paper. Melt the butter and chopped semisweet baking chocolate together in short bursts in the microwave, stirring frequently until silky smooth. Mix in the sugar right away to help the chocolate and butter cool slightly and to create a gorgeous glossy batter. Once the mixture is just warm, whisk in eggs, egg yolk, and vanilla extract until completely combined. This step is crucial for achieving the dense yet tender brownie texture.

Step 3: Combine Dry Ingredients with Wet

Gently fold in the sifted cocoa powder, all-purpose flour, and sea salt into the wet ingredients using a rubber spatula. Stir just until everything is incorporated—overmixing here could toughen your brownies. The batter should be thick and decadent, promising a moist bite once baked.

Step 4: Assemble and Bake the Brownies

Pour half the batter into your prepared pan, smoothing it out evenly. Carefully place the frozen peanut butter sheet right on top, then cover it completely with the remaining batter. The secret to this Peanut Butter Stuffed Brownies Recipe is the seamless layering that encases the peanut butter perfectly inside the rich chocolate. Bake for about 30 minutes until the brownies are set but still slightly gooey in the center, ensuring that fudge-like indulgence remains intact.

Step 5: Cooling and Serving

Let your brownies cool in the pan for 30 minutes to firm up, then gently lift them out using the parchment overhang. Allow them to cool for another half hour at room temperature before slicing to ensure clean, beautiful layers of peanut butter amid the chocolate. Trust me, waiting is a worthy test of patience for these fudgy delights!

Garnishes

Sprinkle a pinch of flaky sea salt on top to elevate the chocolate and peanut butter flavors with just a hint of savory contrast. A dusting of powdered sugar or a drizzle of melted chocolate or peanut butter can add a lovely visual touch and extra flavor appeal for serving guests.

Side Dishes

These brownies are indulgent treats best paired with something light like fresh berries or a scoop of vanilla ice cream to balance the richness. A cold glass of milk or a cup of fresh coffee also complements the deep chocolate and peanut butter notes perfectly, making your dessert moment complete.

Creative Ways to Present

For a fun twist, cut the brownies into small bite-sized squares and serve on a decorative platter with mini skewers at a party. You can even layer them with whipped cream and chopped nuts in dessert glasses for an elegant parfait inspired by this Peanut Butter Stuffed Brownies Recipe.

Make Ahead and Storage

Storing Leftovers

You can keep leftover brownies fresh in an airtight container at room temperature for up to 3 days. If you prefer them extra fudgy, storing them in the fridge for up to 5 days is a great option—the cool temperature intensifies the chocolatey, peanut buttery experience.

Freezing

These brownies freeze beautifully. Wrap individual slices tightly in plastic wrap and place them in a freezer-safe container or bag. Frozen brownies will maintain their flavor and texture for up to 3 months, so you can enjoy your Peanut Butter Stuffed Brownies Recipe whenever a craving hits.

Reheating

To reheat, thaw brownies at room temperature if frozen, then warm slightly in the microwave for 10 to 15 seconds if you want that fresh-baked warmth. This step awakens the gooey center and brings back the fudgy magic you love.

FAQs

Can I use natural peanut butter instead of conventional?

It is best to use creamy conventional peanut butter in this Peanut Butter Stuffed Brownies Recipe because it has a smoother, more consistent texture that holds its shape when frozen. Natural peanut butter tends to separate and may not set as well.

What type of pan is best for these brownies?

An 8-inch square metal pan with parchment paper lining works best. Metal pans conduct heat evenly, which helps your brownies bake through properly while keeping a fudgy texture.

How do I know when the brownies are done?

Look for brownies that are set around the edges but slightly gooey in the center when you gently press the surface. A toothpick inserted near the edges should come out mostly clean or with a few moist crumbs.

Can I substitute the cocoa powder with more melted chocolate?

While melted chocolate adds richness, the unsweetened cocoa powder is important for structure and intense chocolate flavor. For best results, stick to the recipe as written for a perfect balance in this Peanut Butter Stuffed Brownies Recipe.

Will the peanut butter layer melt into the brownies during baking?

The peanut butter layer is frozen before baking, which helps it hold its shape inside the brownie. The surrounding batter sets around it, so you get a distinct, creamy peanut butter center rather than everything blending into one.

Final Thoughts

You really can’t go wrong with the Peanut Butter Stuffed Brownies Recipe when you want a dessert that feels both familiar and excitingly indulgent. The luscious peanut butter core surrounded by rich chocolate brownie is a combination that’s bound to become a favorite in your baking rotation.
