Ingredients

Scale
  • 3 medium ripe bananas, mashed
  • 1/2 cup (113g) unsalted butter, browned and cooled slightly
  • 1/2 cup (100g) granulated sugar
  • 1/4 cup (50g) brown sugar
  • 2 large eggs, room temperature
  • 1 tsp vanilla extract
  • 1 3/4 cups (220g) all-purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 2 tsp ground cinnamon
  • 3/4 cup (75g) toasted walnuts, chopped
  • Optional: 1/4 cup (60g) Greek yogurt or sour cream

Instructions

  1. Brown the butter: In a light-colored skillet over medium heat, melt 1/2 cup (113g) unsalted butter. Stir frequently as it foams and then turns golden brown with a nutty aroma (about 5-7 minutes). Remove from heat and pour into a heatproof bowl to cool slightly.
  2. Preheat the oven to 350°F (175°C). Grease a 9×5 inch loaf pan or line it with parchment paper.
  3. Mix dry ingredients: In a medium bowl, sift together 1 3/4 cups (220g) all-purpose flour, 1 tsp baking soda, 1/2 tsp salt, and 1 tsp ground cinnamon. Set aside.
  4. Prepare the cinnamon swirl: In a small bowl, combine 1 tsp ground cinnamon, 1/4 cup (50g) brown sugar, and 1/4 cup (30g) chopped toasted walnuts.
  5. Combine wet ingredients: In a large bowl, mash the bananas until smooth. Whisk in the browned butter, 1/2 cup (100g) granulated sugar, 2 large eggs, and 1 tsp vanilla extract until well mixed.
  6. Fold in dry ingredients: Gradually add the flour mixture to the wet ingredients, folding gently with a spatula just until combined. Do not overmix; batter should be thick and a little lumpy.
  7. Layer the batter and swirl: Spoon half the batter into the loaf pan, sprinkle half of the cinnamon swirl mixture evenly over it. Add the remaining batter, then top with the rest of the cinnamon swirl. Use a knife or skewer to gently swirl the cinnamon mixture through the batter to create a marbled effect.
  8. Bake: Place the pan in the preheated oven and bake for 55-65 minutes. Check at 55 minutes by inserting a toothpick into the center; it should come out mostly clean with a few moist crumbs. If needed, bake in 5-minute increments. Tent with foil if the top browns too fast.
  9. Cool: Let the bread cool in the pan for 15 minutes before transferring to a wire rack to cool completely.

Notes

Use a light-colored pan to brown butter to watch color changes and avoid burning. Do not overmix batter to keep bread tender. Toast walnuts in a dry pan before chopping for best flavor. Let bread cool before slicing to avoid crumbling. For extra moisture, add Greek yogurt or sour cream if bananas are not very ripe.
