A quick and easy one-bowl chocolate zucchini bread with espresso and walnuts that is moist, rich, and perfect for last-minute baking emergencies or casual treats.

Ingredients

Scale
  • 1 ¾ cups all-purpose flour (220g)
  • ½ cup unsweetened cocoa powder (50g), preferably Dutch-processed
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ¾ cup granulated sugar (150g)
  • ⅓ cup vegetable oil (80ml)
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 ½ cups grated fresh zucchini (about 1 medium zucchini)
  • 1 tablespoon espresso powder
  • ½ cup chopped walnuts (60g), lightly toasted

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×5 inch loaf pan or line it with parchment paper.
  2. Grate the zucchini using a box grater or food processor. No need to peel it. Set aside.
  3. In a large mixing bowl, whisk together the flour, cocoa powder, baking soda, and salt until evenly combined.
  4. Stir in the granulated sugar and espresso powder to the dry mixture.
  5. Add the eggs, vegetable oil, and vanilla extract to the bowl. Stir gently but thoroughly until the batter holds together.
  6. Fold in the grated zucchini and chopped walnuts gently.
  7. Pour the batter into the prepared loaf pan and smooth the top with a spatula.
  8. Bake for 50-60 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs but no raw batter. If needed, bake an additional 5-10 minutes, checking frequently.
  9. Cool the bread in the pan for 10 minutes, then transfer to a cooling rack to cool completely before slicing.

Notes

Do not overmix the batter to avoid tough bread. Grate zucchini finely for even texture. Toast walnuts for extra flavor. Tent with foil if browning too fast. Brush top with melted butter for a glossy finish. Espresso powder enhances chocolate flavor without coffee taste; substitute with instant coffee if needed (reduce oil slightly).
