Ingredients List

- 3 large ripe bananas, mashed
- ½ cup (100g) brown sugar
- ¼ cup (50g) granulated sugar
- ½ cup (120g) sourdough starter (active or discard)
- 2 large eggs, room temperature
- 1 teaspoon pure vanilla extract
- 1 ½ cups (190g) all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
- ½ teaspoon cinnamon (optional but recommended)
- ¼ cup (60ml) milk or buttermilk
- Optional: ½ cup chopped walnuts or dark chocolate chunks
Step-by-Step Instructions
Step 1: Brown the butter
In a saucepan over medium heat, melt the butter. Continue cooking, swirling occasionally, until it foams and turns golden brown with a nutty aroma. Remove from heat immediately and let cool to room temperature.
Step 2: Prepare the wet mixture
In a large mixing bowl, whisk together mashed bananas, brown sugar, granulated sugar, eggs, and vanilla. Add the cooled brown butter and sourdough starter, whisking until fully combined.
Step 3: Mix the dry ingredients
In a separate bowl, combine flour, baking soda, baking powder, salt, and cinnamon.
Step 4: Combine and mix gently
Fold the dry ingredients into the wet mixture, alternating with the milk. Stir until just combined — do not overmix to keep the loaf soft and tender.
Step 5: Add extras and bake
Fold in any optional add-ins like walnuts or chocolate chunks. Pour the batter into a greased and parchment-lined 9×5-inch loaf pan. Bake at 350°F (175°C) for 55–65 minutes or until a toothpick inserted in the center comes out clean.
Step 6: Cool and serve
Let the banana bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing. Enjoy warm or at room temperature.
