This classic sour cream banana bread is incredibly moist, tender, and stays soft for days. Made in one bowl with simple pantry ingredients, it’s the only banana bread recipe you’ll ever need.

Ingredients

Scale
  • 1/2 cup (113g) unsalted butter, melted
  • 3/4 cup (150g) granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 3 medium ripe bananas, mashed (about 1 1/2 cups)
  • 1/2 cup (120g) full fat sour cream
  • 1 1/2 cups (180g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×5 inch loaf pan with butter or non-stick spray, or line with parchment paper.
  2. In a large mixing bowl, melt the butter and let cool for a minute.
  3. Whisk the sugar into the melted butter until combined.
  4. Add the eggs and vanilla extract, whisk vigorously until smooth, pale, and slightly thickened (about 30 seconds).
  5. Add the mashed bananas and sour cream, stir until evenly combined.
  6. Sprinkle the flour, baking soda, and salt over the wet mixture. Fold gently with a spatula until just combined (a few streaks of flour are okay). Do not overmix.
  7. Pour the batter into the prepared loaf pan and spread evenly. Optionally, sprinkle coarse sugar on top.
  8. Bake for 50-60 minutes, until a toothpick inserted in the center comes out clean or with a few moist crumbs. If browning too quickly, tent with foil after 40 minutes.
  9. Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely (about 1 hour) before slicing.

Notes

Use really ripe bananas (heavily spotted or black). Measure flour correctly by spooning into the cup and leveling off. Do not overmix the batter. Room temperature ingredients blend better. Start checking for doneness at 50 minutes. Store at room temperature for up to 4 days; freeze for up to 3 months.
