Instructions

Brownie Layer

  • Preheat oven to 350 degrees F and spray an 8x8 baking pan with cooking spray, then line with a parchment paper sling.
  • In a large bowl, mix together flour, cocoa powder, salt, sugar, eggs, butter, and vanilla until *just* combined.
  • Stir in chocolate chunks, then set aside.

Banana Bread

  • In a large bowl, whisk together melted butter, granulated sugar, brown sugar, buttermilk, vanilla, and egg until well combined.
  • Stir in mashed bananas.
  • Fold in flour, baking soda, cinnamon and salt until *just* combined. Don’t over mix!
  • Pour half the banana batter into the prepared pan, then use a cookie scoop to scoop half the brownie batter on top.
  • Gently swirl the batters together with a knife.
  • Repeat with the remaining batters.
  • Bake in preheated oven for 40 minutes.
  • Cover with tin foil and cook for an additional 15-20 minutes. The center may still be a little gooey, but the top should be golden brown and the outside edges should be set - an inserted toothpick will come out mostly clean.
  • Lift the bars out of the pan immediately.
  • Cool for 10 minutes on a cutting board, then cut and serve.
