Instructions

  1. Step 1: Preheat oven to 350°F. In a microwave-safe bowl, melt 1/2 cup unsalted butter and 8 oz bittersweet chocolate chips together in 30-second intervals, stirring until smooth and glossy.
  2. Step 2: Whisk in 1 cup granulated sugar until combined, then add 2 large eggs and 1 tsp vanilla extract, whisking until smooth.
  3. Step 3: Sift together 3/4 cup all-purpose flour, 1/4 cup unsweetened cocoa powder, and 1/4 tsp salt. Fold the dry ingredients gently into the chocolate mixture until just combined.
  4. Step 4: Pour half the batter into a greased 8x8-inch pan. Drop spoonfuls of 1/3 cup creamy peanut butter evenly over the batter, then pour the remaining batter on top. Use a knife to swirl the peanut butter through the batter.
  5. Step 5: Bake for 25-30 minutes until the edges are set but the center is slightly fudgy. Cool completely before cutting into squares.
