  • Loaf Pan
  • Mixing Bowls
  • Cooling Rack


  • 1 stick Unsalted Butter, melted (8 Tbsp)
  • 1 cup Mashed Ripe Banana (237 mL) (about 2 medium)
  • 1 ¼ cup lightly packed Light Brown Sugar (250 g)
  • 2 Eggs
  • 1 teaspoon Pure Vanilla Extract
  • 1 ¾ cup All Purpose Flour (231 g)
  • cup Peanut Butter Powder (see note)
  • 1 teaspoon Baking Soda
  • ½ teaspoon Salt
  • ¾ cup Semisweet Chocolate Chips or 4 oz chopped Dark Chocolate (plus extra for topping)
  • ½ cup Creamy Peanut Butter


  • Preheat oven to 325°F / 163°C.
  • Spray a loaf pan with nonstick cooking spray.
  • In a large mixing bowl, whisk together melted butter, mashed banana, and brown sugar until evenly combined (it will be slightly lumpy). Whisk in eggs and vanilla.
  • In a second bowl, whisk together flour, peanut butter powder, baking soda, and salt.
  • Pour dry ingredients over wet and stir just until no dry spots remain.
  • Stir chocolate chips into batter.
  • Pour batter into prepared loaf pan. Spoon peanut butter over the top of the batter. Using a knife, draw swirls through the peanut butter so that it blends into the batter. Scatter a few chocolate chips on top.
  • Bake bread until the center is set, 60 to 70 minutes.
  • Allow to cool before slicing and serving.


Peanut Butter Powder - This powder is made from peanuts that have been dehydrated and finely ground. It adds a lot of peanut butter flavor (and protein!) to baked goods. I find PB2 brand at most grocery stores, but also like the Trader Joe’s brand (which is sold near the oatmeal). You can also find it on Amazon here.
