Ingredients

Scale
  • 3 ripe bananas, mashed
  • 1/2 cup (115g) unsalted butter, melted
  • 3/4 cup (150g) granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 1/2 cups (190g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup (90g) semi-sweet chocolate chips or chopped baking chocolate
  • 1/2 cup (60g) chopped walnuts, toasted
  • 2 tablespoons brown sugar
  • 1 tablespoon unsalted butter, melted
  • 1/4 teaspoon ground cinnamon (optional)

Instructions

  1. Preheat oven to 350ยฐF (175ยฐC). Grease a 9×5-inch loaf pan or line with parchment paper.
  2. In a large mixing bowl, mash the ripe bananas with a fork until mostly smooth with some lumps.
  3. Add melted butter and granulated sugar to the bananas and stir until combined.
  4. Beat in the eggs and vanilla extract one at a time, mixing well after each addition.
  5. In a separate bowl, whisk together flour, baking soda, and salt.
  6. Gradually add the dry ingredients to the wet mixture, folding gently until just combined. Avoid overmixing.
  7. Fold in half of the chocolate chips evenly into the batter.
  8. Transfer half the batter to the prepared loaf pan. Sprinkle half of the remaining chocolate chips over it.
  9. Spoon the rest of the batter on top, then scatter the last of the chocolate chips.
  10. Using a butter knife or skewer, gently swirl through the batter to create a marbled chocolate effect without overmixing.
  11. Mix the walnut crunch topping ingredients (toasted walnuts, brown sugar, melted butter, and cinnamon) in a small bowl.
  12. Sprinkle the walnut topping evenly over the batter.
  13. Bake for 55-65 minutes, or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs.
  14. Let the bread cool in the pan for 15 minutes before transferring to a wire rack to cool completely.

Notes

If the top browns too fast, loosely cover with foil halfway through baking. Use ripe bananas for best flavor. Toast walnuts for extra crunch and flavor. Coat chocolate chips with flour to prevent sinking. Room temperature eggs help create a tender crumb.
