Ingredients

Scale
  • 1/2 cup (113g) unsalted butter, browned and cooled
  • 3 medium ripe bananas, mashed (about 1 1/2 cups)
  • 3/4 cup (150g) granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 3/4 cups (220g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 tablespoon espresso powder
  • 3/4 cup (75g) toasted chopped walnuts

Instructions

  1. Brown the butter: Place 1/2 cup unsalted butter in a medium saucepan over medium heat. Stir frequently as it melts and foams. Cook until deep amber color and nutty aroma (5-7 minutes). Pour into a bowl and cool slightly.
  2. Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line with parchment paper.
  3. In a large bowl, combine mashed bananas, granulated sugar, and browned butter. Whisk in eggs one at a time, then stir in vanilla extract.
  4. In a separate bowl, sift together flour, baking soda, and salt.
  5. Gently fold dry ingredients into wet banana mixture until just combined; do not overmix.
  6. In a small bowl, combine espresso powder and toasted walnuts, tossing to coat evenly.
  7. Pour half the batter into the prepared pan. Sprinkle half the espresso walnut mixture evenly over batter. Add remaining batter on top, then scatter remaining espresso walnut mixture. Swirl gently with a knife or skewer to create marbled effect.
  8. Bake for 55-65 minutes, checking at 55 minutes with a toothpick; it should come out mostly clean with a few moist crumbs.
  9. Cool bread in pan for 15 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

Watch butter closely when browning to avoid burning. Use very ripe bananas with brown spots for best sweetness. Do not overmix batter to keep bread tender. Swirl espresso walnut mixture gently for best marbling. Baking times may vary depending on oven and pan type; start checking at 55 minutes. For muffins, bake at 350°F for 18-22 minutes.
