What Makes Chocolate Peanut Butter Brownies So Special?
The Perfect Flavor Combination
Chocolate brings depth and richness, while peanut butter adds a salty, creamy balance. This contrast makes these brownies irresistible.
Texture That Wins Every Time
A proper chocolate peanut butter brownie is fudgy at the center with slightly crisp edges, and the peanut butter swirl adds pockets of creaminess.
Key Ingredients for Chocolate Peanut Butter Brownies
For the Brownie Batter:
- 1/2 cup (113g) unsalted butter – melted and slightly cooled
- 4 oz (115g) semi-sweet chocolate – chopped, or use good-quality chocolate chips
- 1 cup (200g) granulated sugar
- 1/4 cup (50g) light brown sugar – adds moisture and chewiness
- 2 large eggs – at room temperature
- 1 large egg yolk – makes the texture fudgier
- 1 teaspoon vanilla extract
- 2/3 cup (85g) all-purpose flour – spooned and leveled
- 1/3 cup (30g) unsweetened cocoa powder – sifted to remove lumps
- 1/2 teaspoon baking powder – for slight lift (optional if you want denser brownies)
- 1/4 teaspoon salt
For the Peanut Butter Swirl:
- 1/2 cup (125g) creamy peanut butter – smooth works best for swirling
- 2 tablespoons powdered sugar – keeps the swirl stable and slightly sweet
- 2 tablespoons heavy cream or milk – for smoother consistency (optional)
Optional Mix-Ins & Toppings:
- 1/2 cup chocolate chips or chunks
- 1/4 cup chopped roasted peanuts
- Sea salt flakes for garnish
Step-by-Step Method
Step 1: Prepare the Pan and Oven
- Preheat your oven to 350°F (175°C).
- Grease a 9×9-inch baking pan and line it with parchment paper, leaving some overhang for easy removal.
Tip: Lining prevents sticking and makes clean cuts later.
Step 2: Melt the Chocolate & Butter
- In a heatproof bowl, combine butter and semi-sweet chocolate.
- Melt using a microwave (in 20-second bursts, stirring each time) or a double boiler.
- Let the mixture cool slightly.
Tip: Cooling ensures the eggs won’t scramble when added later.
Step 3: Whisk Wet Ingredients
- Add granulated sugar and brown sugar to the melted chocolate-butter mix. Stir until smooth and glossy.
- Whisk in eggs and yolk, one at a time, followed by the vanilla extract.
Tip: Whisking well here adds that signature brownie “crackly top.”
Step 4: Mix Dry Ingredients
- In a separate bowl, sift together flour, cocoa powder, baking powder (if using), and salt.
- Gently fold dry ingredients into the wet mixture using a spatula until just combined.
Tip: Don’t overmix—the less you stir, the fudgier the brownies will be.
Step 5: Make the Peanut Butter Swirl
- In a small bowl, mix peanut butter, powdered sugar, and (if needed) a splash of cream or milk for a creamy consistency.
- This step ensures the peanut butter doesn’t harden while baking.
Step 6: Assemble the Brownies
- Pour half of the brownie batter into the prepared pan.
- Add spoonfuls of peanut butter swirl over the batter.
- Pour remaining brownie batter on top, then drop more peanut butter mixture across the surface.
- Use a knife or skewer to gently swirl—don’t overdo it, or the pattern will disappear.
Tip: Less swirling = more distinct peanut butter ribbons.
Step 7: Bake to Perfection
- Bake in the preheated oven for 30–35 minutes.
- Test with a toothpick inserted into the center—it should come out with moist crumbs, not raw batter.
Tip: Start checking at 28 minutes; every oven varies.
Step 8: Cool and Cut
For sharp edges, chill the brownies in the fridge for 1 hour before slicing into 16 squares.
Tip: Use a hot knife (wiped clean between cuts) for bakery-style squares.
Allow brownies to cool in the pan for at least 30 minutes before lifting them out.
Tips for Fudgy vs. Cakey Brownies
Adjusting Bake Time
Bake for a shorter period for fudgy brownies or a bit longer for cakey ones.
The Role of Eggs
More eggs create structure (cakey), fewer eggs keep the batter dense and fudgy.
