Ingredients
Method
- Preheat oven to 350°F (175°C) and line a 9x5-inch loaf pan with parchment. Whisk together flour, baking soda, cinnamon, and salt in a large bowl.
- Make a well, add mashed bananas, melted butter, both sugars, egg, and vanilla. Stir until combined.
- Pour dry ingredients into wet and fold with a spatula just until no flour streaks remain.
- In a small bowl, combine flour, brown sugar, and cinnamon for the streusel. Cut in cold butter with your fingers until crumbly.
- Scrape batter into pan, smooth top, and sprinkle streusel evenly over it. Bake 55 to 65 minutes until a toothpick has moist crumbs.
- Cool 10 minutes, lift out, and slice warm with a serrated knife.
Notes
If your loaf browns too quickly, tent it loosely with foil after the 40-minute mark. The bread tastes even better the next day, but you’ll lose a little crunch on the topping.
