Equipment

Ingredients
  

  • 1 stick (113 g) unsalted butter (browned)
  • 1 cup (200 g) light brown sugar
  • 1 large egg
  • 2 ½ cups (380 g) overripe bananas (mashed)
  • ½ cup (150 g) full-fat sour cream
  • 2 teaspoons vanilla extract
  • 1 ⅔ cups (200 g) all-purpose flour
  • 1 teaspoon kosher salt
  • ½ teaspoon baking soda
  • 2 teaspoons ground cinnamon
  • cup (100 g) walnuts, halves
  • 1 cup (150 g) raisins
  • 3 tablespoons (40 g) demerara sugar for topping

Instructions
 

  • In a medium pan, cook the butter over medium heat until golden brown and nutty. Transfer to a large bowl and let it cool completely, about 20–40 minutes.
  • Preheat the oven to 350°F (180°C). Grease a 13 x 5-inch loaf pan, line it with parchment paper, and grease again.
  • Add the brown sugar to the cooled butter and beat with an electric mixer until smooth. Add the egg and beat for 3–4 minutes, until pale and fluffy.
  • In a separate bowl, mix the mashed bananas, sour cream, and vanilla extract until smooth and creamy.
  • In another bowl, whisk together the flour, salt, baking soda, and cinnamon.
  • Alternate adding the dry ingredients and banana mixture to the butter mixture, folding gently after each addition. Stir in the walnuts and raisins.
  • Pour the batter into the prepared loaf pan, smoothing the top with a spatula. For an optional decorative touch, place a halved banana on top, cut side up, and gently press it in. Sprinkle demerara sugar evenly over the batter and banana. Bake for 60–70 minutes, or until a toothpick comes out clean. Let the bread cool in the pan for 1 hour before slicing.

Notes

Use Overripe Bananas: The darker and spottier the bananas, the better. They provide the sweetness and flavor that make this bread exceptional.
Brown the Butter Carefully: Stir constantly and watch closely to avoid burning. The butter should turn golden brown with a nutty aroma.
Fold Gently: When combining the batter, fold the ingredients carefully to avoid overmixing, which can make the bread dense.
Cool Before Slicing: Allow the bread to cool for at least 1 hour to ensure clean slices and the perfect texture.
