Instructions

  1. Preheat the oven to 175 ºC (350 °F). Grease a 23 x 10 x 10 cm (9 × 4 x 4-inch) Pullman pan or 9 × 5 × 2¾-inch loaf pan with butter (unless it has a nonstick liner).
  2. In a small bowl, combine 30 grams of the walnuts with a few large pinches of the brown sugar. Set the topping mixture aside.
  3. In a medium bowl, combine the bananas and sourdough starter and use an immersion blender to blend until smooth. (Alternatively, use a potato masher or the back of a fork to mash everything to a smooth puree.)
  4. In a large bowl, whisk together the honey, oil, vanilla, remaining brown sugar, and the eggs. Stir in the banana puree.
  5. In a medium bowl, whisk together the flour, baking soda, salt, cinnamon, and cloves (if using). Fold the flour mixture into the banana mixture and then stir in the remaining walnuts. Pour the batter into the prepared pan and smooth the top with a spatula. Sprinkle on the reserved walnut/brown sugar topping.
  6. Bake for 55 to 65 minutes, or until the internal temperature reaches 93°-96°C (200°-205 °F). Let the loaf cool in the pan for 10 minutes. Remove the loaf from the pan and gently transfer it to a wire rack to thoroughly cool before slicing.
