Ingredients:

  • 2 cups (240g) all-purpose flour
  • 1 tsp (5g) baking soda
  • 1 tsp (2g) baking powder
  • ½ tsp (3g) salt
  • 1 tbsp (6g) ground cinnamon
  • ½ tsp (1g) ground nutmeg
  • 1 cup (200g) granulated sugar
  • ½ cup (100g) packed light brown sugar
  • ½ cup (120ml) vegetable oil
  • 2 large eggs (100g)
  • 1 tsp (5ml) vanilla extract
  • 2 cups (250g) grated zucchini, loosely packed
  • ½ cup (120g) sour cream
  • ½ cup (60g) chopped walnuts
  • ½ cup (90g) semi-sweet chocolate chips

Instructions:

  1. Grate the zucchini using the medium holes of a box grater, keeping the skin on. Measure 2 cups loosely packed. Note: Don't squeeze the water out; we need that moisture!
  2. In a medium bowl, whisk together the all purpose flour, baking soda, baking powder, salt, ground cinnamon, and ground nutmeg. Note: Whisking removes clumps and aerates the flour.
  3. In a separate large bowl, beat the eggs, granulated sugar, and light brown sugar until the mixture is pale. Note: This takes about 2-3 mins and helps the loaf rise.
  4. Stir in the vegetable oil, vanilla extract, and sour cream. Note: Stir until the mixture is smooth and glossy.
  5. Gradually fold the dry ingredients into the wet ingredients until just combined. Note: Stop the moment you see no more streaks of flour.
  6. Gently fold in the grated zucchini, chopped walnuts, and semi sweet chocolate chips. Note: Use a spatula to avoid deflating the air bubbles.
  7. Pour the batter into a greased 9x5 inch loaf pan. Note: Smooth the top with a spoon for an even bake.
  8. Bake at 350°F (175°C) for 55–65 minutes until a toothpick inserted into the center comes out clean or with a few moist crumbs.
