Ingredients:

  • 3 medium overripe bananas, mashed (approx. 1 ½ cups / 350g)
  • 1 ½ cups (150g) grated zucchini, squeezed dry
  • ½ cup (115g) unsalted butter, melted and cooled
  • ½ cup (120g) sour cream
  • 2 large eggs, room temperature
  • ¾ cup (150g) light brown sugar, packed
  • ½ cup (100g) granulated white sugar
  • 1 tsp (5ml) vanilla extract
  • 2 cups (250g) all-purpose flour
  • 1 tsp (5g) baking soda
  • ½ tsp (2g) baking powder
  • ½ tsp (3g) salt
  • 1 tsp (2g) ground cinnamon
  • ¼ tsp (1g) ground nutmeg

Instructions:

  1. Preheat your oven to 325°F (165°C). Grease your loaf pan and line it with parchment paper.
  2. Grate the zucchini, then place it in a clean kitchen towel and squeeze firmly to remove excess water.
  3. In a large bowl, whisk the melted butter and both sugars until smooth.
  4. Beat in the eggs one at a time, then stir in the mashed bananas, sour cream, and vanilla until the mixture is glossy and uniform.
  5. Sift the flour, baking soda, baking powder, salt, cinnamon, and nutmeg directly over the wet ingredients.
  6. Use a rubber spatula to fold the dry ingredients in gently until no flour streaks remain, then fold in the squeezed zucchini.
  7. Pour batter into the pan and bake for 60–70 minutes, or until a toothpick inserted in the center comes out clean with a few moist crumbs.
