Ingredients

  • 1 cup grated zucchini (approximately one medium zucchini)
  • 1 cup all-purpose flour
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar packed
  • 1/2 cup unsweetened cocoa powder
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup vegetable oil
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup semi-sweet chocolate chips
  • 1/2 teaspoon ground cinnamon

Instructions

  • Grate zucchini using the fine side of a box grater or food processor; do not squeeze out moisture. Preheat oven to 350°F (175°C) and grease or line an 8-inch square baking pan with parchment paper.
  • In a medium bowl, sift together flour, cocoa powder, baking powder, baking soda, salt, and ground cinnamon.
  • In a large bowl, whisk granulated sugar, brown sugar, and vegetable oil until combined. Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
  • Gradually fold dry ingredients into wet mixture until just combined. Fold in grated zucchini and chocolate chips evenly.
  • Pour batter into prepared pan and smooth the top. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  • Cool cake in pan for 15 minutes then transfer to wire rack to cool completely. Serve warm or at room temperature.
