Ingredients

Scale
  • 1/2 cup (113g) unsalted butter
  • 3 large ripe bananas, mashed (about 1 1/2 cups or 340g)
  • 1/2 cup (100g) granulated sugar
  • 1/4 cup (50g) packed light brown sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1/2 cup (120g) plain Greek yogurt or sour cream
  • 1 1/2 cups (190g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/2 teaspoon salt
  • 1/4 cup (30g) all-purpose flour (for streusel)
  • 1/4 cup (50g) packed light brown sugar (for streusel)
  • 1/2 teaspoon ground cinnamon (for streusel)
  • 3 tablespoons (42g) cold unsalted butter, cut into small cubes (for streusel)
  • 1/2 cup (60g) chopped walnuts (for streusel)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line it with a strip of parchment paper, leaving some overhang on the long sides.
  2. Place the 1/2 cup of unsalted butter in a light-colored saucepan over medium heat. Swirl the pan occasionally as it melts. It will foam and sputter. Once the foam subsides and golden brown specks form at the bottom, remove from heat immediately and pour into a heatproof bowl. Let cool for 10-15 minutes.
  3. In a large bowl, mash the overripe bananas with a fork until mostly smooth with a few small lumps.
  4. To the mashed bananas, add the cooled brown butter, granulated sugar, brown sugar, eggs, vanilla extract, and Greek yogurt. Whisk until smooth and well combined.
  5. In a separate bowl, whisk together the all-purpose flour, baking soda, cinnamon, nutmeg, and salt.
  6. Pour the dry ingredients into the wet ingredients. Use a rubber spatula to fold them together gently until just a few streaks of flour remain. Do not overmix.
  7. In a small bowl, combine the flour, brown sugar, and cinnamon for the streusel. Add the cold, cubed butter and use your fingers or a pastry cutter to work it into the dry ingredients until it looks like coarse, crumbly sand. Stir in the chopped walnuts.
  8. Pour the batter into the prepared loaf pan and spread into an even layer. Sprinkle the walnut streusel generously over the top, pressing down very lightly.
  9. Bake for 50-65 minutes, until a wooden skewer inserted into the center comes out clean or with just a few moist crumbs. If the top browns too quickly, tent loosely with aluminum foil after about 40 minutes.
  10. Let the bread cool in the pan on a wire rack for 15 minutes. Then, using the parchment paper handles, lift it out and let it cool completely on the rack.

Notes

Don’t walk away from the browning butter; it can go from perfect to burnt in 30 seconds. Use a light-colored pan to see the color change. Let the brown butter cool before adding to eggs to avoid scrambling. Fold gently to avoid overmixing. Check baking soda freshness by testing with vinegar.
