This Chocolate Zucchini Bread features both cocoa powder and chocolate chips for an extra chocolatey and moist zucchini bread recipe. Quick and easy to make too!


  • 1 ½ cups grated zucchini (2 small or 1 medium zucchini)
  • ½ cup (118ml) vegetable oil
  • 2 large eggs
  • 2 teaspoons (10ml) pure vanilla extract
  • ¼ cup (48g) sour cream
  • 1 cup (190g) granulated sugar
  • 1 cup (140g) all-purpose flour
  • ½ cup (40g) natural unsweetened cocoa powder
  • 1 teaspoon (5g) ground cinnamon
  • 1 teaspoon (4g) baking soda
  • 1 ¼ teaspoon (5) baking powder
  • 1 teaspoon (5g) salt
  • ½ cup (112g) semi-sweet chocolate chips (plus additional for garnish)


  1. Preheat the oven to 350°F. Generously grease a 9-inch loaf pan and line with parchment paper. Set aside.
  2. Using the large cheese grater, grate the zucchini with the skin on. Use a paper towel to squeeze out extra water from the zucchini and fluff with a fork.
  3. In a large mixing bowl, combine the eggs, oil, sour cream, and vanilla extract. Beat all the ingredients together until well combined. Add the sugar and beat until incorporated.
  4. Combine the remaining dry ingredients in a large mixing bowl and whisk to combine. Add the dry ingredients to the bowl and beat just until it starts to combine.
  5. Fold in the chocolate chips and zucchini using a spatula and finish mixing the batter by hand. Pour the batter into the prepared pan. Sprinkle a few extra chocolate chips on top.
  6. Bake at 350°F for 50-55 minutes or until a toothpick inserted in the center of the loaf comes out clean. Cool for at least 1 hour before slicing.


Storing: Keep stored in an airtight container on the counter for 3 days.

Freezing: Allow it to cool completely. Then wrap in plastic wrap followed by aluminum foil. I usually also put it in a freezer Ziploc for added freezer-burn protection.
