Prep and Cook Time
- Preparation: 15 minutes
- Cooking: 30 minutes
- Total: 45 minutes
Yield
12 generously sized brownies
Difficulty Level
Medium – Ideal for bakers comfortable with swirling techniques and precise baking.
Ingredients
- 1 cup unsalted butter, melted and cooled
- 2 cups granulated sugar
- 4 large eggs
- 1 teaspoon pure vanilla extract
- 1 cup all-purpose flour, sifted
- ¾ cup unsweetened cocoa powder, sifted
- ½ teaspoon fine sea salt
- ½ teaspoon baking powder
- 1 cup creamy peanut butter (natural preferred for richness)
- 2 tablespoons powdered sugar
- 1 teaspoon milk (optional, to adjust peanut butter consistency)
Instructions
- Preheat your oven to 350°F (175°C) and line a 9×13 inch baking pan with parchment paper, allowing some overhang for easy removal.
- Prepare the brownie batter: In a large mixing bowl, whisk together the melted butter and granulated sugar until smooth and glossy. Add eggs one at a time, beating well after each addition for that rich, velvety texture. Stir in vanilla extract.
- Combine dry ingredients: In a separate bowl, sift together all-purpose flour, cocoa powder, salt, and baking powder to ensure a lump-free, even mix.
- Fold dry into wet: Gradually incorporate the dry ingredients into the wet mixture, folding gently until just combined-avoid overmixing to maintain fudgy brownies.
- Prepare the peanut butter swirl: In a small bowl, blend peanut butter with powdered sugar. Add milk, a drizzle at a time, until the peanut butter reaches a spreadable consistency-smooth but thick enough to hold swirls.
- Layer and swirl: Pour half of the chocolate batter into the prepared pan. Dollop spoonfuls of peanut butter mixture over the batter. Pour remaining brownie batter on top carefully. Using a butter knife or skewer, create swirls by dragging through the layers with gentle circular motions-aim for a marbled, organic look without overmixing.
- Bake: Place in the oven and bake for 28-32 minutes. Insert a toothpick into the center; it should come out with a few moist crumbs but no wet batter for perfect fudginess.
- Cool completely: Allow brownies to cool in the pan on a wire rack before cutting into squares. This step is crucial to set the swirl and develop that decadent dense texture.
Tips for Success
- Peanut Butter Choice: Opt for natural peanut butter without additives for a deeper, more authentic flavor. Stir well before measuring to ensure even consistency.
- Swirling Technique: Use slow, deliberate motions while creating swirls. Over-swizzling can blend the flavors and lose the signature marbled look.
- Make Ahead: Brownies store beautifully in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. For best results, bring to room temperature before serving.
- Substitutions: For a twist, substitute peanut butter with almond or cashew butter, adjusting the sweetness if needed.
- Troubleshooting: If brownies are cakey, reduce baking powder by half next time. If too gooey, increase bake time by 3-5 minutes while checking frequently.
Creative Serving Suggestions to Elevate Your Brownie Experience
For an elevated presentation, dust the brownies lightly with cocoa powder or powdered sugar. A scoop of vanilla bean ice cream pairs beautifully, melting softly atop warm brownies. Try drizzling warm salted caramel or chocolate ganache over slices for an added layer of indulgence. Garnish with chopped roasted peanuts or a sprig of fresh mint to invite both aroma and texture into the experience. Serve on rustic wooden boards or delicate dessert plates to emphasize the handcrafted charm.

The swirl isn’t just for show-it infuses each bite with a perfect balance of bittersweet chocolate and luscious peanut butter, elevating the classic brownie to a gourmet treat.

Using a knife or skewer, you gently drag through the peanut butter and chocolate batter to create mesmerizing, marbled swirls. It’s like painting with flavors-both artful and delicious.
Q3: Can I use crunchy peanut butter or is smooth essential?

Q6: Can these brownies be made gluten-free or vegan?
A6: They can be adapted! Use gluten-free flour blends and ensure your peanut butter is natural and free of added dairy. For a vegan twist, substitute eggs with flax or chia seeds and use dairy-free chocolate. The fudgy texture might shift slightly, but the decadence and flavor fusion remain spectacular.
Q7: Why is the fusion of peanut butter and chocolate so irresistible?
A7: Peanut butter brings a salty, savory note that perfectly cuts through the sweetness of chocolate, creating a harmony of flavors that satisfies cravings on multiple levels. Together, they create a comforting richness that feels both nostalgic and luxuriously indulgent.
