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

  1. 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.
  2. Preheat Oven: Set oven to 350°F (177°C) and re-line the pan with fresh parchment paper.
  3. 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.
  4. Sift in flour, cocoa powder, and salt. Fold gently until combined — do not overmix.
  5. 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.
  6. Bake: Bake for 30 minutes, until the edges are set but the center is slightly moist.
  7. Cool & Serve: Let brownies cool in the pan for 30 minutes, then lift out with parchment. Cool another 30 minutes before slicing.

Notes

  • Use conventional creamy peanut butter for the best texture.
  • Avoid overmixing to keep brownies dense and fudgy.

  • Add espresso powder or chili flakes for a flavor twist.
  • Store at room temperature up to 3 days or refrigerate for up to 5 days.
  • Freeze up to 2 months; thaw overnight before serving.
