Ingredients

For the Streusel

  • 3 tablespoon unsalted butter, cold
  • ½ cup brown sugar
  • ½ cup all purpose flour
  • 1 teaspoon cinnamon
  • ¼ teaspoon salt

For the Banana Bread

  • ½ cup unsalted butter, softened
  • 1 ¼ cup granulated sugar
  • 2 eggs, at room temperature
  • 1 teaspoon vanilla
  • 1 cup very ripe mashed bananas about 2 large bananas
  • ¾ cup buttermilk, at room temperature
  • 1 ¾ cups all purpose flour
  • 2 teaspoon cinnamon
  • 1 teaspoon baking soda
  • ¾ teaspoon salt

Instructions

For the Streusel

  • Add the cold butter, flour, brown sugar, cinnamon and salt to a small bowl.
  • Combine everything together. It's easiest to do this with your fingers, "mashing" everything together. It should be in large crumbles once combined.
  • Chill the streusel in the fridge while making the banana bread.

For the Banana Bread

  • Preheat oven to 350 degrees. Grease a 9x5-inch loaf pan and line it with parchment paper. (The parchment paper is not optional! The banana bread won't bake properly without it.) Set aside.
  • In a large bowl cream the butter and granulated sugar together with an electric mixer.
  • Add in the eggs and vanilla and mix for one minute until pale and fluffy.
  • Then mix in the mashed banana and buttermilk.
  • Add in the flour, cinnamon, baking soda and salt and mixt until thoroughly combined
  • Pour the batter into the prepared loaf pan. Sprinkle the streusel over the top, making sure to cover the whole surface.
  • Bake the banana bread for 60-70 minutes, or until a toothpick comes out clean from the center with only a few moist crumbs.
  • Allow the banana bread to cool in the pan for 30 minutes, or until cool enough to handle.
  • Transfer the bread to a cooling rack to completely cool, or enjoy warm. The banana bread does taste best when it is completely cooled though!
  • Store the leftovers in an airtight container for up to three days.
