Assembly
  1. Spread half the brownie batter into the bottom of the pan.
  2. Dollop the peanut butter mixture over the batter and smooth it out, leaving a small border.
  3. Top with the remaining brownie batter, using spoonfuls to cover the peanut butter layer.
  4. Bake for 28 to 35 minutes until shiny on top with set edges and soft center.
  5. Cool completely in the pan before slicing for neat squares.
  6. For clean cuts, chill the brownies for 45 minutes and use a hot knife.
