Instructions
To make the peanut butter swirl:
  1. Stir the powdered sugar, peanut butter, melted butter, and salt together in a medium bowl.
To make the chocolate brownie batter:
  1. Preheat the oven to 325 degrees F, mist a 9x9-inch pan with non-stick spray, and line it with parchment.
  2. Place the sugar, melted butter, cocoa, and salt in a large bowl and stir together until combined.
  3. Stir in the eggs.
  4. Add the flour and baking powder, and mix until smooth.
  5. Stir in the vanilla, then pour half the batter into the prepared pan.
  6. Drop about half the peanut butter swirl mixture in dollops over the surface of the brownie batter. Swirl with the tip of a knife.
  7. Layer the remaining brownie batter on top, and repeat the peanut butter swirl.
  8. Bake for 45 to 60 minutes, or until set around the edges but still soft towards the center.
  9. Cool completely in the pan, then transfer to a cutting board and cut into squares.
