Sourdough Banana Bread Recipe

Introduction

It combines the natural tang of sourdough starter with the sweetness of ripe bananas, creating a loaf that’s moist, tender, and packed with flavor. Whether you’re a long-time baker or just starting out, this recipe is approachable and rewarding.

Another reason this recipe is so loved is that it’s a clever way to use up leftover sourdough starter while also preventing ripe bananas from going to waste.

Step-by-Step Instructions

Step 1: Preheat your oven to 350°F (175°C) and grease a 9×5-inch loaf pan or line it with parchment paper.

Step 2: In a large mixing bowl, mash the ripe bananas until smooth. Stir in the sourdough starter, melted butter, brown sugar, eggs, and vanilla extract. Mix until well combined.

Step 3: In a separate bowl, whisk together flour, baking soda, baking powder, salt, and cinnamon.

Step 4: Gradually fold the dry ingredients into the wet mixture, stirring until just combined. Do not overmix to keep the bread light and tender.

Step 5: If using, gently fold in chopped nuts or chocolate chips.

Step 6: Pour the batter into the prepared loaf pan and spread evenly.

Step 7: Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean. If the top browns too quickly, tent with foil during the last 15 minutes.

Step 8: Remove from the oven and let the bread cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
