Ingredients:

  • 2 cups (250g) all-purpose flour
  • 3/4 cup (75g) unsweetened cocoa powder
  • 1 1/2 cups (300g) granulated sugar
  • 1 tsp (5g) baking soda
  • 1/2 tsp (3g) baking powder
  • 1/2 tsp (3g) salt
  • 1 tsp (2g) ground cinnamon
  • 3 large eggs
  • 1/2 cup (120ml) vegetable oil
  • 1 tsp (5ml) vanilla extract
  • 1/2 cup (120ml) sour cream
  • 2 cups (250g) grated zucchini
  • 1 cup (150g) semi-sweet chocolate chips
  • 8 oz (225g) cream cheese
  • 1/2 cup (115g) unsalted butter
  • 3 cups (360g) powdered sugar
  • 1 tsp (5ml) vanilla extract
  • 2 tbsp (30ml) heavy cream

Instructions:

  1. Preheat oven to 350°F (175°C) and grease a 9x9 inch square pan or 9-inch round pan.
  2. In a medium bowl, whisk together the flour, cocoa powder, sugar, baking soda, baking powder, salt, and cinnamon until no large cocoa clumps remain.
  3. In a large bowl, beat the eggs, vegetable oil, vanilla, and sour cream until the mixture is smooth and pale.
  4. Pour the dry ingredients into the wet ingredients and stir until just combined. Gently fold in the grated zucchini and chocolate chips.
  5. Pour the batter into the prepared pan and bake for 30–35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  6. For the frosting, beat softened cream cheese and butter until fluffy. Gradually add powdered sugar, vanilla, and heavy cream.
  7. Once the cake is completely cool, spread the frosting in a thick layer across the top.
