A moist, double-chocolate quick bread recipe that uses shredded zucchini for moisture without affecting the flavor. This recipe avoids common pitfalls like gummy crumb or excess moisture.

Ingredients

Scale
  • 1 cup granulated sugar
  • 1/2 cup packed light brown sugar
  • 1/2 cup unsalted butter, melted
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 1/4 cups all-purpose flour
  • 1/2 cup unsweetened Dutch-process cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon cinnamon
  • 1 cup shredded zucchini (about 1 medium zucchini, unpeeled)
  • 1 cup semi-sweet chocolate chips

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan.
  2. In a large bowl, whisk together the granulated sugar, brown sugar, and melted butter until combined.
  3. Beat in the eggs one at a time, then stir in the vanilla extract.
  4. In a separate medium bowl, whisk together the flour, cocoa powder, baking soda, salt, baking powder, and cinnamon.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  6. Gently fold in the shredded zucchini and chocolate chips.
  7. Pour the batter into the prepared loaf pan and spread evenly.
  8. Bake for 50-65 minutes, or until a wooden skewer inserted into the center comes out clean.
  9. Let the bread cool in the pan for 10-15 minutes before transferring it to a wire rack to cool completely.

Notes

  • You do not need to squeeze the zucchini; its moisture contributes to the bread’s tenderness.
  • Dutch-process cocoa powder provides a richer, darker chocolate flavor and color compared to natural cocoa powder.
  • For a double chocolate experience, you can add an extra 1/2 cup of chocolate chips to the batter.
  • This bread freezes well. Wrap cooled slices tightly in plastic wrap, then in foil, and freeze for up to 3 months.
