Ingredients

Scale
  • 3 large very ripe bananas, mashed
  • 1/2 cup unsalted butter, melted
  • 3/4 cup granulated sugar
  • 1 large egg, lightly beaten
  • 1 teaspoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon ground cinnamon
  • 1 cup fresh or frozen blueberries
  • Optional Crumb Topping: 1/4 cup all-purpose flour, 1/4 cup packed brown sugar, 2 tablespoons cold unsalted butter, 1/4 teaspoon ground cinnamon

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a standard 9×5 inch loaf pan.
  2. In a large bowl, mix the mashed bananas, melted butter, granulated sugar, egg, and vanilla extract until just combined.
  3. In a separate medium bowl, whisk together the flour, baking soda, salt, and cinnamon.
  4. Gradually add the dry ingredients to the wet ingredients, mixing only until the flour streaks disappear. Do not overmix.
  5. Gently fold in the blueberries. If using frozen berries, do not thaw them first.
  6. If making the crumb topping, combine the topping ingredients using your fingers or a fork until coarse crumbs form. Sprinkle evenly over the batter in the loaf pan.
  7. Pour the batter into the prepared loaf pan and spread evenly.
  8. Bake for 50 to 65 minutes, or until a wooden skewer inserted into the center comes out clean. If the top browns too quickly, loosely tent it with foil.
  9. Let the bread cool in the pan for 10 minutes before carefully turning it out onto a wire rack to cool completely before slicing.

Notes

  • For the juiciest berries, gently toss the blueberries with one teaspoon of flour before folding them into the batter. This helps prevent them from sinking.
  • This bread freezes well. Wrap the cooled loaf tightly in plastic wrap and then foil for up to three months.
  • If you do not have ripe bananas, you can bake this as a simple Blueberry Bread by omitting the bananas and increasing the melted butter to 3/4 cup.
