This one-banana banana bread recipe only requires a single banana to create one mini loaf. It’s perfect for those leftover bananas!


  • 4 tablespoons unsalted butter, diced
  • ¼ cup brown sugar
  • ¼ cup sugar
  • 1 large egg
  • 1 large overripe banana, mashed
  • 1 teaspoon vanilla extract
  • 2/3 cup all-purpose flour
  • ½ teaspoon cinnamon
  • ¼ teaspoon baking powder
  • 1/8 teaspoon baking soda
  • 1/8 teaspoon salt


  1. Preheat the oven to 350 degrees Fahrenheit. Lightly grease a mini loaf pan with baking spray and set aside.
  2. In a small saucepan, gently cook the butter over medium-low heat, stirring regularly. Once the butter is completely melted, begin stirring more often. The butter will melt, sizzle, and foam as it browns. The butter will slowly turn from pale yellow to golden and you will see dark flecks forming in the mixture. Once fragrant, remove from the heat immediately by pouring into a medium-sized mixing bowl.
  3. Add the brown sugar and sugar to the browned butter and stir to combine. Next, add in the egg, banana, and vanilla extract, stirring after each addition. Finally, toss in the flour, cinnamon, baking powder, baking soda, and salt. Stir just until combined. Pour the batter into a prepared pan and bake in the oven for about 35-40 minutes or until a toothpick inserted barely comes out clean. Allow to cool slightly before removing from the pan to cool completely.


  • If you don’t have a mini loaf pan, you can bake this in a standard sized loaf pan. Baking time will be less, approximately 22-25 minutes total.
