  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • teaspoon baking soda
  • ½ teaspoon kosher salt
  • cups mashed bananas, approximately 3-4 ripe bananas
  • ½ cup (113g or 1 stick) butter, softened
  • cups (300g) granulated sugar
  • 2 large eggs, room temperature
  • ¼ cup buttermilk, room temperature
  • 2 teaspoons vanilla


  • Preheat oven to 350°F and spray a 9x5-inch loaf pan with nonstick cooking spray.
  • In a medium bowl, sift together flour, baking powder, baking soda, and salt. (Do not skip this step!) Set aside.
  • In a separate medium bowl, use a fork to mash the bananas and set aside.
  • In a stand mixer on medium-high, cream butter and sugar together for about 2 minutes, stopping to scrape the sides of the bowl as needed.
  • With the mixer on low speed, add eggs, one at a time. Add in buttermilk and vanilla until the batter is just combined (about a minute).
  • Slowly pour the flour mixture into the egg mixture, about ½ cup at a time. Mix on low until just combined.
  • Remove the bowl from the mixer and fold in the mashed bananas until evenly incorporated throughout the batter.
  • Pour the batter into the prepared pan and bake for 65-70 minutes, checking the bread at 50 minutes. The bread is done when a toothpick comes out mostly clean with a few crumbs, but no wet batter.
