Description

A rich, moist, and flavorful banana bread with the nuttiness of browned butter and the subtle tang of sourdough starter. Perfect for breakfast, snacks, or dessert.


Ingredients

  • 1/2 cup unsalted butter
  • 3 overripe bananas, mashed
  • 1/2 cup sourdough starter (active or discard)
  • 1/2 cup brown sugar
  • 1/4 cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 3/4 cups all-purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1/2 tsp cinnamon (optional)
  • Optional mix-ins: 1/2 cup chopped walnuts, pecans, or chocolate chips

Instructions

  1. Brown the butter in a saucepan over medium heat until golden with a nutty aroma, then let it cool slightly.
  2. Mash the bananas in a large bowl, then mix in the sourdough starter, brown sugar, granulated sugar, eggs, vanilla extract, and cooled brown butter.
  3. In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon if using.
  4. Stir the dry ingredients into the wet mixture until just combined, being careful not to overmix.
  5. Fold in any optional mix-ins like nuts or chocolate chips.
  6. Pour the batter into a greased or parchment-lined loaf pan.
  7. Bake at 350°F (175°C) for 55–65 minutes, or until a toothpick inserted into the center comes out clean.
  8. Cool the bread in the pan for 10–15 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

  • Optional: swirl in peanut butter or cream cheese for extra flavor.
  • Can make muffins by reducing baking time to 20–25 minutes.
  • For a fall twist, add a pinch of nutmeg or clove.
  • For dairy-free version, use plant-based butter.
  • Store tightly wrapped at room temperature for up to 3 days or in the fridge for up to 5 days; freezes well.
  • Reheat slices in the microwave for 10–15 seconds or toast them.
