Ingredients

Scale
  • 3 medium ripe bananas, mashed (about 1 1/4 cups)
  • 2 cups (240 g) all-purpose flour
  • 1/2 cup (120 ml) sour cream, full-fat preferred
  • 3/4 cup (150 g) granulated sugar
  • 1/4 cup (50 g) packed brown sugar
  • 1/2 cup (115 g) unsalted butter, melted and slightly cooled
  • 2 large eggs, room temperature
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract
  • Cinnamon Sugar Crust:
  • 2 tablespoons granulated sugar
  • 1 teaspoon ground cinnamon

Instructions

  1. Preheat the oven to 350°F (175°C). Grease a 9×5-inch loaf pan lightly with butter or non-stick spray, then dust with flour and tap out excess.
  2. In a large bowl, whisk together the flour, baking soda, baking powder, and salt; set aside.
  3. In a separate bowl, whisk the granulated sugar, brown sugar, eggs, and melted butter until smooth. Stir in the sour cream and vanilla extract.
  4. Fold the mashed bananas into the wet mixture gently until combined.
  5. Add the dry ingredients to the wet banana mixture in two additions, folding gently after each. Avoid overmixing.
  6. Pour the batter into the prepared loaf pan and smooth the top with a spatula.
  7. Mix the cinnamon sugar crust ingredients (granulated sugar and cinnamon) and sprinkle evenly over the batter.
  8. Bake for 55-65 minutes, starting to check at 55 minutes with a toothpick; it should come out with a few moist crumbs but no wet batter.
  9. Let the bread cool in the pan for 10 minutes, then transfer to a cooling rack to cool completely before slicing.

Notes

If the cinnamon sugar crust browns too quickly, tent the bread with foil halfway through baking. Let the bread cool completely before slicing to avoid a gummy texture. Use very ripe bananas for best flavor and sweetness. Avoid overmixing the batter to keep the bread tender.
