This is the only ultra moist banana bread recipe you need. Using sour cream and brown sugar, this easy, one-bowl method guarantees a tender, bakery-style loaf every time you bake with your overripe bananas.

Ingredients

Scale
  • 1 3/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/2 cup (1 stick) unsalted butter, softened
  • 3/4 cup packed light brown sugar
  • 1/4 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon pure vanilla extract
  • 1 cup mashed very ripe bananas (about 3 large)
  • 1/4 cup sour cream or plain Greek yogurt

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a standard 9×5 inch loaf pan.
  2. In a medium bowl, whisk together the flour, baking soda, salt, and cinnamon. Set this dry mixture aside.
  3. In a large bowl, use an electric mixer or a sturdy whisk to beat the softened butter, brown sugar, and granulated sugar until the mixture is light and creamy, about 2 minutes. This step builds texture.
  4. Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  5. Mix in the mashed bananas and the sour cream until just combined. Do not overmix at this stage.
  6. Add the dry ingredient mixture to the wet ingredients. Mix on low speed or fold gently with a spatula until just combined. Stop mixing as soon as you see no streaks of flour remaining. Overmixing develops gluten and causes dry bread.
  7. Pour the batter evenly into your prepared loaf pan.
  8. Bake for 55 to 65 minutes, or until a wooden skewer inserted into the center comes out clean or with moist crumbs attached.
  9. Let the banana bread cool in the pan on a wire rack for 15 minutes. Then, carefully remove the loaf from the pan and let it cool completely on the rack before slicing for the best texture.

Notes

  • Use bananas that are heavily spotted or nearly black for the deepest flavor and best moisture retention.
  • For an extra crackly top, sprinkle 1 tablespoon of coarse granulated sugar over the batter before baking.
  • If you prefer chocolate chip banana bread, fold in 1 cup of semi-sweet chocolate chips with the dry ingredients.
