Ingredients:

  • 1 ½ cups (190g) all-purpose flour
  • ½ cup (45g) Dutch-process cocoa powder
  • 1 tsp (5g) baking soda
  • ½ tsp (3g) salt
  • ½ cup (110g) neutral oil
  • 1 cup (200g) granulated sugar
  • 2 large (100g) eggs
  • 1 tsp (5ml) vanilla extract
  • ½ cup (120g) full-fat sour cream
  • 2 cups (230g) grated zucchini
  • 1 cup (170g) semi-sweet chocolate chips

Instructions:

  1. Preheat your oven to 350°F (175°C). Grease your loaf pan with butter or line it with parchment paper.
  2. In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt until no lumps remain.
  3. In a large bowl, whisk the oil and sugar together. Add the eggs one at a time, followed by the vanilla and sour cream. Beat by hand until the mixture looks smooth and glossy.
  4. Pour the dry ingredients into the wet ingredients. Using a silicone spatula, fold gently until just combined—stop as soon as you see no more streaks of flour.
  5. Fold in the grated zucchini and ¾ cup of chocolate chips. Do not over-mix.
  6. Pour the batter into the prepared pan and smooth the top. Sprinkle the remaining ¼ cup of chocolate chips over the surface.
  7. Bake for 55–65 minutes. The bread is done when a toothpick inserted into the center comes out with a few moist crumbs.
  8. Let the bread cool in the pan for 10 minutes before transferring to a wire rack.
