Prep and Cook Time
- Preparation: 15 minutes
- Cooking: 25-30 minutes
- Total Time: 40-45 minutes
Yield
Approximately 16 brownies, depending on the size of your slices.
Difficulty Level
Medium – Perfect for enthusiastic bakers ready to master the art of swirling and balancing rich flavors.
Ingredients
- 1 cup unsalted butter, melted
- 2 cups granulated sugar
- 4 large eggs, room temperature
- 1 teaspoon pure vanilla extract
- 1 cup all-purpose flour, sifted
- 3/4 cup unsweetened cocoa powder, sifted
- 1/2 teaspoon salt
- 1 cup creamy peanut butter (natural or classic, stirred until smooth)
- 1/4 cup powdered sugar (optional for peanut butter swirls)
Instructions
- Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
- Mix the base. In a large bowl, combine the melted butter and granulated sugar. Whisk vigorously until glossy and well incorporated.
- Add eggs and vanilla. Beat in eggs one at a time,ensuring each is fully blended before adding the next. Stir in the vanilla extract.
- Combine dry ingredients. In a separate bowl, sift together flour, cocoa powder, and salt. Gradually fold the dry mixture into the wet ingredients. Be careful not to overmix; the batter should be thick and fudgy.
- Prepare the peanut butter swirl. For a smoother, sweeter swirl, mix the peanut butter with powdered sugar until it forms a spreadable consistency. If you prefer a more intense nutty flavor, use pure creamy peanut butter as is.
- Layer the batter. Pour two-thirds of the chocolate brownie batter into the prepared pan, spreading evenly.
- Add dollops. Spoon dollops of the peanut butter mixture over the batter. Scatter gently but avoid overcrowding.
- Top with remaining batter. Spoon the remaining brownie batter over the peanut butter dollops as evenly as possible.
- Create the swirl. Using a butter knife or skewer, drag through the batter in a figure-eight or swirling motion to create lovely, marbled patterns. Take care not to overdo it; bold, defined swirls hold their visual appeal best.
- Bake for 25-30 minutes, or until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs attached.
- Cool completely in the pan on a wire rack before slicing.This rest time firms the brownies and enhances the texture contrast between the fudgy chocolate and creamy peanut butter.
Tips for Success with Your Decadent Peanut Butter Swirl Brownies
- Use high-quality cocoa powder for a deep chocolate flavor; Dutch-processed cocoa enhances richness but natural cocoa provides a tangy intensity.
- Room temperature eggs whisk more smoothly into the batter, creating a better emulsion for fudgier brownies.
- Gently fold dry ingredients to avoid activating gluten, which keeps brownies tender rather of cakey.
- The swirl technique is crucial: don’t over-swirl or the peanut butter and chocolate will fully blend,losing the distinct visual and textural contrast.
- For a peanut butter twist, try sprinkling chopped roasted peanuts or chocolate chips on top before baking.
- Make ahead tip: These brownies store well at room temperature in an airtight container for up to 3 days, or freeze cut portions for longer storage.
Serving Suggestions to Elevate Your Brownie Experience

For a visually stunning presentation,dust the brownies lightly with cocoa powder or drizzle with melted dark chocolate. Garnish with a few roasted peanuts or a sprinkle of flaky sea salt to amplify the nutty-sweet profile.
