Ingredients Equipment Method Notes

Ingredients
  

Banana bread batter
  • 3 ripe bananas
  • 0.5 cup creamy peanut butter
  • 0.33 cup butter melted
  • 0.75 cup sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1.5 cup all-purpose flour
  • 1 tsp baking soda
  • 0.5 tsp salt
  • 1 cup dark or semi-sweet chocolate chips
  • 2 tbsp extra peanut butter for swirling

Equipment

  • 1 sheet pan
  • 1 cast iron skillet

Method
 

Preheat and grease
  1. Preheat the oven to 350°F and grease a 9x5 loaf pan.
  2. Set the prepared loaf pan aside while you mix the batter.
Mix the wet ingredients
  1. Whisk mashed bananas, peanut butter, melted butter, sugar, eggs, and vanilla together until smooth and combined.
Combine dry ingredients and fold in chips
  1. Fold in all-purpose flour, baking soda, and salt until just combined.
  2. Fold in chocolate chips, then stop mixing as soon as they’re evenly distributed.
Swirl and bake
  1. Pour the batter into the loaf pan and dollop the extra peanut butter across the top.
  2. Swirl the top with a knife to create ribbon-like peanut butter streaks.
  3. Bake at 350°F for 60–70 minutes until deeply golden and a toothpick comes out with just a few moist crumbs.
Cool and slice
  1. Cool the loaf in the pan for 15 minutes before turning it out.
  2. Slice only when fully cooled to keep the swirl and chocolate pockets from smearing.

Notes

Pro tip: use very ripe bananas for the best banana flavor and moisture. Store the loaf tightly wrapped at room temperature for 3 days or refrigerated for up to 5 days; freeze sliced pieces in a freezer-safe bag for up to 3 months. For a lighter option, swap half the butter for unsweetened applesauce and use dark chocolate chips to maintain richness with less fat.
