Ingredients

Scale
  • 3 ripe bananas (about 1 1/2 cups mashed)
  • 1/2 cup (113g) unsalted butter, browned
  • 3/4 cup (150g) granulated sugar
  • 1/4 cup (50g) packed brown sugar
  • 2 large eggs, room temperature
  • 1 3/4 cups (220g) all-purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 tsp vanilla extract
  • 1/2 cup (about 150g) Nutella

Instructions

  1. Brown the Butter: Place 1/2 cup (113g) unsalted butter in a medium saucepan over medium heat. Stir frequently as it melts, foams, and then turns golden brown with nutty aroma (about 5 minutes). Remove from heat and let cool slightly.
  2. Preheat Oven and Prepare Pan: Preheat oven to 350°F (175°C). Grease a 9×5 inch (23×13 cm) loaf pan with butter or line it with parchment paper for easy removal.
  3. Mash Bananas: In a large bowl, mash 3 ripe bananas until smooth but still slightly chunky.
  4. Mix Sugars and Eggs: Add 3/4 cup granulated sugar and 1/4 cup packed brown sugar to bananas. Crack in 2 room temperature eggs and whisk until blended.
  5. Add Browned Butter and Vanilla: Slowly pour the slightly cooled brown butter into the banana mixture along with 1 tsp vanilla extract. Stir gently until combined.
  6. Combine Dry Ingredients: In a separate bowl, sift or whisk together 1 3/4 cups (220g) all-purpose flour, 1 tsp baking soda, and 1/2 tsp salt.
  7. Fold Dry into Wet: Gradually add the dry ingredients to the wet banana mixture. Use a rubber spatula to fold gently until just combined — don’t overmix or the bread will be tough.
  8. Prepare Nutella Swirl: Warm 1/2 cup (150g) Nutella slightly in the microwave (~15 seconds) to make it easier to swirl.
  9. Assemble for Baking: Pour half of the banana batter into the loaf pan. Dollop half the Nutella over the batter in spoonfuls. Add the remaining batter on top, then dollop the rest of the Nutella. Use a knife or skewer to swirl the Nutella through the batter, creating a marbled effect.
  10. Bake: Place in the oven and bake for 55-65 minutes. Check doneness by inserting a toothpick in the center — it should come out with a few moist crumbs but no raw batter. If the top browns too fast, tent loosely with foil.
  11. Cool: Let the bread cool in the pan on a rack for 15 minutes, then remove from the pan and cool completely before slicing.

Notes

Watch the brown butter closely and stir constantly to avoid burning. Use very ripe bananas with brown spots for best sweetness and moisture. Do not overmix the batter to keep the bread tender. Warm Nutella slightly before swirling to prevent clumps. Tent with foil if the bread browns too quickly. For extra moisture, add a tablespoon of sour cream or Greek yogurt to the wet mix.
