Ingredients

Scale
  • 1 1/2 cups (190g) all-purpose flour
  • 1/2 cup (40g) unsweetened cocoa powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 2 large eggs, room temperature
  • 1/2 cup (100g) granulated sugar
  • 1/2 cup (100g) packed brown sugar
  • 1/2 cup (120ml) vegetable oil
  • 1 teaspoon vanilla extract
  • 1/3 cup (80ml) buttermilk, room temperature
  • 1 1/2 cups grated zucchini, squeezed dry
  • 1/2 cup (90g) semi-sweet chocolate chips
  • For the Ganache:
  • 1/2 cup (90g) semi-sweet chocolate chips
  • 1/3 cup (80ml) heavy cream
  • 1 tablespoon butter

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan; line with parchment paper for easy removal.
  2. Grate zucchini and squeeze out excess moisture using a clean kitchen towel or cheesecloth. Set aside.
  3. In a large bowl, whisk together flour, cocoa powder, baking soda, baking powder, and salt.
  4. In a separate bowl, whisk eggs, granulated sugar, brown sugar, oil, vanilla, and buttermilk until smooth.
  5. Pour wet ingredients into dry; fold with a rubber spatula until just combined. Do not overmix.
  6. Fold in squeezed zucchini and 1/2 cup chocolate chips until evenly distributed.
  7. Pour batter into prepared pan and spread evenly. Bake for 50-60 minutes, until a toothpick inserted in center comes out with moist crumbs (not wet batter). Tent with foil after 40 minutes if browning too quickly.
  8. Cool in pan on a wire rack for 15 minutes, then lift out and cool completely.
  9. For ganache: Place 1/2 cup chocolate chips and butter in a heat-safe bowl. Heat cream until simmering, pour over chocolate, let sit 1 minute, then whisk until smooth.
  10. Drizzle ganache over cooled loaf. Let set 15-20 minutes before slicing.

Notes

Squeezing the zucchini dry is crucial to avoid a soggy loaf. Room temperature ingredients help create a smooth batter. For a gluten-free version, use a 1:1 gluten-free baking blend. For dairy-free, use dairy-free buttermilk, chocolate chips, and coconut cream in the ganache.
