Peanut Butter Filling
- 3/4 cup smooth peanut butter (not natural)
- 1 cup powdered sugar (110 grams)
- 1 teaspoon vanilla extract
Brownie Batter
- 1/2 cup all-purpose flour (63 grams)
- 1/4 cup cocoa powder (22 grams)
- 1/4 teaspoon salt
- 1/2 cup unsalted butter (112 grams)
- 6 ounces semi-sweet chocolate or 50-60% dark chocolate (180 grams)
- 1 cup granulated sugar (200 grams)
- 2 large eggs
- 1 large egg yolk (discard the white)
- 1 teaspoon vanilla extract
- Preheat Oven and Prepare Pan: Preheat your oven to 350°F (180°C). Line an 8×8 inch (20×20 cm) baking pan with parchment paper, ensuring there is an overhang on the sides. Lightly grease the pan first to help the parchment paper stick.
- Make Peanut Butter Filling: In a medium bowl, beat together the smooth peanut butter, powdered sugar, and vanilla extract until fully combined and smooth. If your powdered sugar is lumpy, sift it before mixing. Refrigerate this filling while you prepare the brownie batter.
- Combine Dry Ingredients for Brownies: In a small bowl, whisk together the all-purpose flour, cocoa powder, and salt. Set aside for later.
- Melt Butter and Chocolate: In a large heatproof bowl, melt the unsalted butter and chopped semi-sweet chocolate together. You can microwave on medium power in 45-second intervals, stirring between each, or melt gently over a double boiler. Allow the mixture to cool for about 5 minutes.
- Add Sugar and Eggs: Whisk the granulated sugar into the slightly cooled chocolate and butter mixture. Then, beat in the 2 large eggs, the additional egg yolk, and vanilla extract until the mixture is glossy and smooth without clumps.
- Mix in Dry Ingredients: Sift the dry flour mixture into the chocolate mixture to avoid lumps. Whisk everything together until the batter is smooth with no streaks of dry ingredients.
- First Layer of Brownie Batter: Pour half of the brownie batter into the prepared baking pan. Use a spatula to spread it evenly into a flat layer.
- Add Peanut Butter Layer: Remove the peanut butter filling from the fridge. Scoop tablespoons of the filling, flatten each slightly, and evenly distribute them over the brownie batter layer. It’s okay if it doesn’t cover the entire surface.
- Top with Remaining Brownie Batter: Spoon the remaining brownie batter gently over the peanut butter layer, taking care not to disturb it. Spread this layer evenly to cover the peanut butter completely.
- Bake the Brownies: Place the pan in the middle of the preheated oven and bake for 32-37 minutes. The brownies are done when the top looks set and a toothpick inserted in the center comes out clean or with just a few moist crumbs, but no raw batter.
- Cool and Slice: Let the brownies cool completely in the pan until the pan is no longer warm to touch, which can take a few hours. To speed cooling, place the pan on a wire rack in the refrigerator. When cool, use the parchment paper overhang to lift the brownies out of the pan onto a cutting board. Slice into 12 squares with a sharp knife.
Notes
- Use smooth, commercially prepared peanut butter, not natural varieties where oil separates.
- If using salted butter, omit the added salt from the recipe.
- Semi-sweet or 50-60% dark chocolate works best; stronger dark chocolates may overpower the peanut butter.
- Store brownies in an airtight container at room temperature for up to 4 days.
- For longer storage, freeze brownies tightly wrapped in a freezer-safe container for up to 3 months; thaw in the refrigerator before serving.
- Nutrition estimates are based on cutting the brownies into 12 equal pieces.
