Ingredients

Scale
  • 1/2 cup all-purpose flour (streusel topping)
  • 1/2 cup packed light brown sugar (streusel topping)
  • 1 tsp ground cinnamon (streusel topping)
  • 1/4 cup unsalted butter, melted (streusel topping)
  • 1 1/2 cups all-purpose flour (bread)
  • 1 tsp baking soda (bread)
  • 1/2 tsp salt (bread)
  • 1/2 tsp ground cinnamon (bread)
  • 3 ripe bananas, mashed
  • 1/2 cup granulated sugar (bread)
  • 1/4 cup packed light brown sugar (bread)
  • 1/2 cup unsalted butter, melted (bread)
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1/3 cup granulated sugar (cinnamon swirl)
  • 1 tbsp ground cinnamon (cinnamon swirl)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line it with parchment paper.
  2. Mix streusel topping: Whisk together 1/2 cup flour, 1/2 cup brown sugar, and 1 tsp cinnamon. Stir in 1/4 cup melted butter with a fork until crumbly. Set aside.
  3. Prepare cinnamon swirl by combining 1/3 cup granulated sugar and 1 tbsp ground cinnamon in a small bowl.
  4. In a medium bowl, whisk together 1 1/2 cups flour, 1 tsp baking soda, 1/2 tsp salt, and 1/2 tsp cinnamon.
  5. In a large bowl, stir together mashed bananas, 1/2 cup granulated sugar, 1/4 cup brown sugar, 1/2 cup melted butter, eggs, and vanilla extract until smooth.
  6. Fold dry ingredients into wet ingredients gently until no flour streaks remain; do not overmix.
  7. Pour half of the batter into the prepared loaf pan. Evenly sprinkle the cinnamon-sugar mixture over the batter.
  8. Top with the remaining batter and gently swirl with a butter knife to create a marbled cinnamon pattern.
  9. Sprinkle streusel topping generously over the loaf.
  10. Bake for 50 to 60 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Tent with foil if top browns too quickly.
  11. Allow to cool in pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

Use very ripe bananas with heavy speckles or black skin for best sweetness and moisture., Bring eggs and butter to room temperature before mixing for a tender loaf., Measure flour by spooning into cup and leveling to prevent a dry dense loaf., Mix batter just until dry ingredients disappear to avoid tough texture., Prepare streusel topping up to 2 days ahead and refrigerate., Add 1/2 to 3/4 cup chopped walnuts or pecans for crunch., Add 1/2 to 3/4 cup chocolate chips for a chocolate twist., Replace up to half all-purpose flour with whole wheat or gluten-free blends to alter texture., Top cooled loaf with vanilla glaze or cream cheese frosting for a bakery-style finish., Loaf yields approximately 10 slices.
