Pro Tips
Don’t Overmix the Batter: When combining dry and wet ingredients, stir gently until just combined. Overmixing can make brownies cakier instead of fudgy.
Create Distinct Swirls: Drop spoonfuls of peanut butter over the brownie batter and gently swirl with a knife. Avoid overblending, or you’ll lose the visual contrast and defined flavor pockets.
Watch the Bake Time: Baking a few minutes too long can dry out the brownies. Remove when the edges are set but the center still jiggles slightly. The brownies will finish cooking as they cool.
Other tips include lining your pan with parchment paper for easy removal and using a sharp knife to cut clean squares after cooling. Small touches like these make your brownies bakery-quality.
Instructions
Step 1: Preheat and Prepare Pan
Preheat your oven to 350°F (175°C). Line an 8×8-inch (20x20cm) baking pan with parchment paper and lightly grease the sides.
Step 2: Mix Wet Ingredients
In a large mixing bowl, whisk together melted butter and sugar until smooth. Beat in eggs one at a time, then add vanilla extract.
Step 3: Add Dry Ingredients
Sift cocoa powder, flour, salt, and baking powder into the bowl. Fold gently until just combined, being careful not to overmix.
Step 4: Prepare Peanut Butter Swirl
In a small bowl, mix peanut butter, sugar, and vanilla extract until creamy and smooth.
Step 5: Layer and Swirl
Pour brownie batter into prepared pan and smooth the top. Drop spoonfuls of peanut butter mixture evenly over the batter. Using a knife, gently swirl to create a marbled effect.
Step 6: Optional Topping
Sprinkle chopped peanut butter cups over the top for added texture and flavor.
Step 7: Bake
Bake for 25–30 minutes until edges are set and the center slightly jiggles. Do not overbake to maintain fudginess.
Step 8: Cool and Slice
Allow brownies to cool completely in the pan. Lift out using parchment paper and slice into squares.
