Ingredients:
- 1 ½ cups (190g) all-purpose flour
- ½ cup (45g) unsweetened cocoa powder
- 1 tsp (5g) baking soda
- ½ tsp (3g) salt
- ½ cup (115g) unsalted butter, melted and cooled
- ¾ cup (150g) granulated sugar
- ¼ cup (50g) brown sugar, packed
- 2 large eggs (100g)
- 1 tsp (5ml) vanilla extract
- ¼ cup (60g) sour cream
- 1 ½ cups (225g) grated zucchini (unpeeled)
- 1 cup (170g) semi-sweet chocolate chips
Instructions:
- Preheat oven to 350°F (175°C). Grease a 9x5 loaf pan and line the bottom with parchment paper.
- Grate the zucchini using a box grater or a food processor shredding disc.
- In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth.
- Beat in the eggs one at a time, then stir in the vanilla extract and sour cream until the mixture is glossy and combined.
- Whisk in the flour, cocoa powder, baking soda, and salt. Stir just until the white streaks of flour disappear; do not overmix.
- Gently fold in the grated zucchini and chocolate chips using a spatula until evenly distributed.
- Pour the batter into the prepared pan. Bake for 50–60 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
- Let the loaf rest in the pan for 10 minutes before transferring to a wire rack to cool.
