Equipment

  • Mixing bowl
  • Measuring cups & spoons
  • Fork or potato masher
  • Whisk or spoon
  • Hand mixer or stand mixer (optional)
  • 9x5-inch loaf pan
  • Oven
  • Cooling rack

Ingredients
  

  • 1 ½ cups all-purpose flour Standard flour for baking.
  • 1 teaspoon baking soda Helps the bread rise.
  • ½ teaspoon salt Enhances flavor.
  • 1 cup sourdough starter Use an active, well-fed starter for best results.
  • 3 ripe bananas Must be well-ripened for best sweetness and moisture.
  • 2 large eggs
  • ½ cup sugar Brown sugar can be used for a richer flavor.
  • ½ cup unsalted butter Softened, not melted, for better mixing.
  • 1 teaspoon vanilla extract Adds a lovely aroma.
  • 1 cup chopped walnuts or pecans Optional, adds texture and flavor.

Instructions
 

  • Preheat your oven to 350°F (175°C) and grease a 9x5-inch loaf pan or line it with parchment paper.
  • In a large mixing bowl, combine the flour, baking soda, and salt. Set aside.
  • In another bowl, cream the softened butter and sugar together until light and fluffy. Add the eggs, one at a time, mixing well after each addition.
  • Stir in the mashed bananas and vanilla extract.
  • Gradually add the sourdough starter to the wet ingredients, mixing until fully incorporated.
  • Slowly fold in the dry ingredients, being careful not to overmix. Gently stir in the chopped nuts.
  • Pour the batter into the prepared loaf pan and spread it evenly.
  • Bake for 50–60 minutes, or until a toothpick inserted into the center of the bread comes out clean.
  • Remove the bread from the oven and let it cool in the pan for 10 minutes. Then, transfer it to a cooling rack to cool completely.
  • Slice and enjoy! Optionally, serve with butter or cream cheese for an added touch of indulgence.

Notes

Ensure you utilize ripe bananas displaying brown spots on the skin as they offer the ideal sweetness & moisture levels. If your sourdough starter lacks full maturity, it may not contribute substantial flavor, so remember to feed it regularly to maintain activity. You can experiment by incorporating nuts like walnuts, pecans, or even a combination to suit your taste preferences. For sweeter bread, feel free to increase the amount of sugar in it. After baking, allow the bread to cool entirely before slicing to prevent excessive moisture or crumbling. As an extra treat, toast a slice & spread butter or cream cheese for a delicious snack throughout the day. Store leftovers in an airtight container at room temperature for up to three days or freeze for longer storage.
