Difficulty Level
Easy to Medium: Ideal for bakers with basic skills equipped to handle simple swirling techniques.
Ingredients
- 1 cup (2 sticks) unsalted butter, melted and cooled
- 2 cups granulated sugar
- 3 large eggs, room temperature
- 1 teaspoon pure vanilla extract
- 1 cup all-purpose flour, sifted
- ¾ cup unsweetened cocoa powder, sifted
- ½ teaspoon kosher salt
- ½ teaspoon baking powder
- ¾ cup creamy peanut butter, room temperature
- ¼ cup powdered sugar (for the swirl)
- 2 tablespoons heavy cream (optional) – adds silkiness to the peanut butter swirl
- ½ cup chopped roasted peanuts (optional, for crunch)
Instructions
- Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
- In a large bowl, combine melted butter and granulated sugar. Whisk the mixture is well combined, about 2 minutes.
- Add eggs one at a time, whisking thoroughly after each addition to create a smooth, homogenous batter. Stir in vanilla extract.
- In a separate bowl, sift together flour, cocoa powder, salt, and baking powder. Gradually fold these dry ingredients into the wet mixture using a rubber spatula. Avoid overmixing to keep the batter light yet fudgy.
- Prepare the peanut butter swirl: In a small bowl, blend peanut butter with powdered sugar and heavy cream (if using). Mix until silky and slightly thickened.
- Pour the brownie batter into the prepared pan, spreading evenly. Drop spoonfuls of the peanut butter mixture randomly over the batter.
- Master the swirl: Use a butter knife or skewer to create a marbled pattern by swirling gently in broad, slow “S” or figure-eight motions. Be careful not to over-swirl to maintain distinctive ribbons of peanut butter amidst the chocolate.
- optional: Sprinkle chopped roasted peanuts evenly over the top for textural contrast.
- Bake for 28-32 minutes, or until a toothpick inserted just into the chocolate part comes out with a few moist crumbs (avoid fully clean to retain fudgy softness).
- Allow brownies to cool completely in the pan on a wire rack. Use parchment overhang to lift and slice into squares. Serve at room temperature for the best fudge experience.
Tips for Success
- Choose high-quality cocoa powder – it makes a robust chocolate flavor that elevates the entire dessert.
- Room-temperature eggs and peanut butter ensure smooth blending and better texture.
- To achieve the ultimate fudgy texture, avoid overbaking and test early, starting at 28 minutes.
- For a more intense peanut butter flavor, use natural peanut butter, but balance the sweetness carefully with extra powdered sugar.
- Make ahead: These brownies store beautifully in an airtight container for up to four days and intensify in flavor overnight.
