This incredibly moist and tender banana bread uses sour cream for a soft, delicate crumb that stays fresh for days. Made with simple ingredients, it’s the perfect way to use overripe bananas.

Ingredients

Scale
  • 3 medium ripe bananas, mashed
  • 1 ½ cups (190g) all-purpose flour
  • ¾ cup (150g) granulated sugar
  • ½ cup (120g) full-fat sour cream
  • ⅓ cup (75g) unsalted butter, melted
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ½ cup chocolate chips (optional)
  • ½ cup chopped walnuts (optional)
  • Cinnamon sugar for topping (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line with parchment paper, letting it hang over the long sides.
  2. In a large bowl, mash the ripe bananas with a fork or potato masher until mostly smooth with a few small lumps.
  3. Add melted butter, sour cream, eggs, and vanilla extract to the mashed bananas. Whisk until smooth and creamy.
  4. In a medium bowl, whisk together flour, sugar, baking soda, and salt until evenly combined.
  5. Pour dry ingredients into wet mixture. Fold with a rubber spatula until just combined—do not overmix. A few lumps are okay.
  6. If using, gently fold in chocolate chips or nuts.
  7. Pour batter into prepared loaf pan and spread evenly. Sprinkle cinnamon sugar on top if desired.
  8. Bake for 55-65 minutes, starting to check at 50 minutes. Bread is done when a toothpick inserted in center comes out clean or with a few moist crumbs. If top browns too quickly, loosely cover with foil at 40 minutes.
  9. Cool in pan for 10 minutes, then lift out using parchment and transfer to a cooling rack. Cool completely before slicing.

Notes

Use full-fat sour cream for best texture. Room temperature ingredients are important for even mixing. Do not overmix batter to avoid tough bread. Let bread cool completely before slicing to prevent crumbling. Flavor improves overnight.
