Ingredients
Scale
For the Peanut Butter Filling:
- 1 ¼ cups creamy peanut butter (conventional, not natural)
For the Brownie Batter:
- 10 tablespoons unsalted butter (or plant-based alternative)
- 4 ounces semisweet baking chocolate, finely chopped (or dairy-free chocolate)
- 1 cup granulated sugar
- 2 large eggs
- 1 egg yolk
- 1 teaspoon vanilla extract
- ½ cup all-purpose flour (or gluten-free flour blend)
- ¼ cup unsweetened cocoa powder, sifted
- ¼ teaspoon fine salt
Optional Add-ins:
- ¼ cup chopped peanuts or chocolate chips
- Sea salt flakes, for topping
Instructions
- Prepare Peanut Butter Layer: Warm peanut butter in a microwave-safe bowl for 20–30 seconds until pourable. Line an 8-inch square pan with parchment paper, leaving overhangs. Spread the peanut butter evenly in the pan and freeze for 1 hour. Once solid, lift the peanut butter sheet out using the parchment and return to the freezer.
- Preheat Oven: Set oven to 350°F (177°C) and re-line the pan with fresh parchment paper.
- Make Brownie Batter: In a microwave-safe bowl, combine butter and chopped chocolate. Microwave in 30-second intervals, stirring after each, until smooth. Whisk in sugar and let cool slightly. Add eggs, yolk, and vanilla; whisk for 1 minute until glossy.
- Sift in flour, cocoa powder, and salt. Fold gently until combined — do not overmix.
- Assemble: Spread half of the brownie batter into the prepared pan. Place the frozen peanut butter sheet on top, then spread remaining batter to cover completely.
- Bake: Bake for 30 minutes, until the edges are set but the center is slightly moist.
- Cool & Serve: Let brownies cool in the pan for 30 minutes, then lift out with parchment. Cool another 30 minutes before slicing.

- Ensure peanut butter layer is fully frozen before baking.
