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.
