Ingredients

Scale
  • 3 medium ripe bananas, mashed (about 1 ½ cups)
  • 1 ½ cups (190 grams) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ½ cup (113 grams) unsalted butter, softened
  • ¾ cup (150 grams) granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • ½ cup (125 grams) creamy peanut butter
  • ½ cup (120 ml) heavy cream
  • ¾ cup (130 grams) semi-sweet chocolate chips

Instructions

  1. Preheat your oven to 350°F (175°C). Grease your 9×5-inch loaf pan with butter or line it with parchment paper for easy removal.
  2. In a medium bowl, whisk together the dry ingredients: 1 ½ cups (190 g) all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt. Set aside.
  3. In a large bowl, cream the butter and sugar: Using a mixer on medium speed, beat ½ cup (113 g) softened unsalted butter with ¾ cup (150 g) granulated sugar until light and fluffy, about 3 minutes.
  4. Add eggs and vanilla: Beat in 2 large eggs, one at a time, then mix in 1 teaspoon vanilla extract. The mixture should be smooth and slightly thick.
  5. Stir in mashed bananas: Fold in 3 medium ripe bananas (about 1 ½ cups mashed). The batter will be thick and fragrant.
  6. Combine wet and dry ingredients: Gradually add the flour mixture to the banana mixture, folding gently with a spatula until just combined. Be careful not to overmix to keep the bread tender.
  7. Prepare the peanut butter swirl: Warm ½ cup (125 g) creamy peanut butter slightly in the microwave (about 20 seconds) to loosen it.
  8. Add batter to the loaf pan: Pour half of the banana bread batter into the prepared pan and smooth the top.
  9. Drop spoonfuls of peanut butter over the batter: Use a knife or skewer to swirl the peanut butter through the batter, creating a marbled effect.
  10. Top with remaining batter: Spread the rest of the banana batter over the peanut butter swirl, then swirl again lightly to create ribbons of peanut butter on top.
  11. Bake for 55-60 minutes: The bread is done when a toothpick inserted into the center comes out clean or with just a few moist crumbs. If the top browns too quickly, tent loosely with foil halfway through.
  12. Cool in the pan for 15 minutes: Then transfer to a wire rack to cool completely before adding ganache.
  13. Make the chocolate ganache: Heat ½ cup (120 ml) heavy cream in a small saucepan over medium heat until it just begins to simmer. Pour over ¾ cup (130 g) semi-sweet chocolate chips in a heatproof bowl. Let sit 2 minutes, then stir until smooth and glossy.
  14. Pour ganache over cooled banana bread: Spread evenly and let set for about 20 minutes at room temperature or chill briefly to firm up.

Notes

Do not overmix the batter after adding flour to keep the bread tender. Warm peanut butter slightly to make swirling easier. Let the bread cool completely before adding ganache to prevent it from melting and becoming runny. Tent the bread with foil if it browns too quickly during baking.
