Instructions
- Step 1: Preheat the oven to 350°F (175°C). Grease an 8x8-inch baking pan and line it with parchment paper, leaving an overhang for easy removal.
- Step 2: In a microwave-safe bowl, melt 1/2 cup unsalted butter and 1 cup semisweet chocolate chips together in 30-second intervals, stirring between each, until smooth and glossy.
- Step 3: Stir in 1 cup granulated sugar and 1/2 cup brown sugar into the melted chocolate mixture until combined and slightly cooled.
- Step 4: Add 2 large eggs, one at a time, beating well after each addition, then mix in 1 tsp vanilla extract until smooth.
- Step 5: Sift together 3/4 cup all-purpose flour, 1/4 cup unsweetened cocoa powder, and 1/4 tsp salt; fold gently into the chocolate batter until just combined.
- Step 6: Pour half the batter into the prepared pan, then drop spoonfuls of 1/3 cup creamy peanut butter evenly on top; pour the remaining batter over and use a knife to swirl the peanut butter through the batter.
- Step 7: Bake for 30-35 minutes until a toothpick inserted near the center comes out with moist crumbs but not wet batter.
- Step 8: Let cool completely in the pan on a wire rack before lifting out using the parchment overhang; cut into 16 squares and serve.
