Ingredients

Scale
  • 3 to 4 very ripe bananas (about 1 1/2 cups mashed)
  • 2 cups (240 g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon cinnamon
  • 3/4 cup (150 g) granulated sugar
  • 1/4 cup packed (50 g) brown sugar
  • 1/2 cup (115 g) unsalted butter, melted and cooled
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 cup (170 g) chocolate chunks (dark or semi-sweet)
  • For the Streusel Crumb Topping:
  • 1/2 cup (60 g) all-purpose flour
  • 1/3 cup packed (65 g) brown sugar
  • 1/2 teaspoon ground cinnamon
  • 4 tablespoons (60 g) unsalted butter, cold and cut into small pieces
  • Pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×5 inch loaf pan with butter or nonstick spray and set aside.
  2. In a medium bowl, mash 3 to 4 ripe bananas until mostly smooth with a few small lumps (about 1 1/2 cups).
  3. Add melted butter, granulated sugar, brown sugar, eggs, and vanilla extract to the mashed bananas. Stir gently until combined.
  4. In a large bowl, whisk together flour, baking soda, salt, and cinnamon.
  5. Add the wet mixture to the dry ingredients and stir gently with a spatula or wooden spoon just until the flour disappears. The batter should be thick and lumpy. Avoid overmixing.
  6. Fold in chocolate chunks evenly through the batter.
  7. In a small bowl, combine flour, brown sugar, cinnamon, and salt for the streusel topping. Cut in cold butter using a pastry cutter or two forks until mixture resembles coarse crumbs.
  8. Spoon batter into the greased loaf pan and smooth the top. Evenly sprinkle the streusel crumb topping over the batter.
  9. Bake for 55 to 65 minutes. Start checking at 55 minutes by inserting a toothpick in the center; it should come out with a few moist crumbs but no wet batter.
  10. Let the bread cool in the pan on a wire rack for 15 minutes, then remove from pan and cool completely on the rack.

Notes

Use very ripe bananas for natural sweetness and moisture. Do not overmix the batter to avoid dense bread. Keep butter cold for streusel topping to get crumbly texture. Chocolate chunks melt unevenly creating gooey pockets. Tent with foil if streusel browns too quickly. Let bread cool before slicing to prevent crumbling. Variations include adding nuts, using gluten-free flour, or making dairy-free/vegan substitutions.
