Ingredients

Scale
  • 3 medium ripe bananas, mashed
  • 1/2 cup peanut butter (creamy or crunchy, natural and unsweetened preferred)
  • 1 1/2 cups all-purpose flour (190g) – can substitute almond flour for gluten-free
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 3/4 cup granulated sugar (150g) – brown sugar can be substituted
  • 2 large eggs, room temperature
  • 1/2 cup unsalted butter (115g), melted and slightly cooled
  • 1 teaspoon vanilla extract
  • 1/2 cup chocolate chips or chopped dark chocolate (90g), 60-70% cocoa recommended
  • 1/4 cup heavy cream (60ml)
  • 1/4 cup additional chopped chocolate (45g) for ganache

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9×5-inch loaf pan or line with parchment paper.
  2. In a medium bowl, whisk together flour, baking soda, baking powder, and salt. Set aside.
  3. In a large bowl, mash bananas until smooth but slightly chunky. Stir in peanut butter and sugar until combined.
  4. Whisk in eggs and vanilla extract.
  5. Slowly pour in melted butter while stirring gently to keep batter moist.
  6. Fold dry ingredients into wet ingredients using a spatula until just combined; avoid overmixing.
  7. Gently fold in chocolate chips or chopped chocolate.
  8. Pour half the batter into the loaf pan. Dollop spoonfuls of peanut butter and chocolate on top. Pour remaining batter over and use a butter knife to swirl, creating a marbled effect.
  9. Bake for 55-65 minutes. Check doneness at 55 minutes with a toothpick; it should come out clean or with a few moist crumbs.
  10. While baking, heat heavy cream until just simmering. Pour over chopped chocolate in a bowl and let sit 2 minutes. Stir until smooth and glossy to make ganache.
  11. Cool bread in pan for 15 minutes, then transfer to wire rack. While warm, pour ganache over top, letting it drip down the sides.

Notes

Do not overmix the batter to avoid dense bread. Use very ripe bananas for best sweetness and moisture. Let bread cool before glazing with ganache to prevent it from sliding off. For extra chocolate pockets, fold in an additional 1/4 cup chocolate chips before baking. Room temperature eggs blend better. Bananas can be ripened in a 300°F oven for 10-15 minutes if needed. For dairy-free, substitute butter and cream with coconut oil and full-fat coconut milk.
