This banana bread is transformed by the deep, nutty flavor of brown butter, resulting in an exceptionally moist and complex loaf. It tastes even better the next day as the flavors meld, making it perfect for making ahead.

Ingredients

Scale
  • 1/2 cup (1 stick / 113g) unsalted butter, for browning
  • 1 3/4 cups (220g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon fine sea salt
  • 3/4 cup (150g) packed light brown sugar
  • 1/4 cup (50g) granulated sugar
  • 2 large eggs, room temperature
  • 1/3 cup (80g) plain full-fat yogurt or sour cream
  • 1 teaspoon pure vanilla extract
  • 1 1/2 cups mashed very ripe bananas (about 3-4 bananas)

Instructions

  1. Brown the butter: Melt butter in a light-colored saucepan over medium heat, swirling often, until it foams, crackles, and develops golden brown solids with a nutty aroma (5-8 min). Pour into a heat-proof bowl and cool for 15-20 min.
  2. Prep: Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line with parchment paper.
  3. Mix dry ingredients: In a medium bowl, whisk together flour, baking soda, and salt.
  4. Combine wet ingredients: In a large bowl, whisk cooled brown butter, brown sugar, and granulated sugar for 1 minute. Whisk in eggs one at a time, then yogurt and vanilla until smooth. Stir in mashed bananas with a spatula.
  5. Combine batter: Add dry ingredients to wet ingredients. Fold gently with a spatula until just combined and no dry flour remains. Do not overmix.
  6. Bake: Pour batter into prepared pan and smooth the top. Bake for 55-65 minutes, until a toothpick inserted in the center comes out clean. Tent with foil if top browns too quickly.
  7. Cool: Let bread cool in pan for 15 minutes, then transfer to a wire rack using parchment paper. Cool completely before slicing for best texture.

Notes

For best results, use very ripe, spotty bananas. The bread tastes better on the second day. For add-ins, fold in 3/4 cup chocolate chips or walnuts after mixing. Store wrapped at room temperature for 3-4 days, refrigerate for a week, or freeze for up to 3 months.
