Ingredients

Scale
  • 1 ¾ cups (220g) all-purpose flour
  • ½ cup (45g) unsweetened cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ¾ cup (150g) granulated sugar
  • ½ cup (100g) packed brown sugar
  • 2 large eggs, room temperature
  • ½ cup (120ml) vegetable oil or melted coconut oil
  • 1 teaspoon vanilla extract
  • 1 ½ cups (about 180g) grated zucchini, squeezed dry
  • ¾ cup (130g) semi-sweet chocolate chips
  • 1 cup (120g) powdered sugar, sifted (for glaze)
  • 2 teaspoons instant espresso powder (for glaze)
  • 2 tablespoons (30ml) hot water (for glaze)
  • 1 teaspoon vanilla extract (for glaze)

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9×5-inch loaf pan or line with parchment paper.
  2. Grate zucchini and squeeze out excess moisture using a clean kitchen towel. Set aside.
  3. In a large bowl, whisk together flour, cocoa powder, baking soda, and salt until evenly combined.
  4. In a separate bowl, beat granulated sugar, brown sugar, eggs, vegetable oil, and vanilla extract until smooth and creamy (2-3 minutes).
  5. Slowly fold dry ingredients into wet mixture until just combined; avoid overmixing.
  6. Fold in grated zucchini and chocolate chips evenly.
  7. Pour batter into prepared loaf pan and smooth the top.
  8. Bake for 50 to 60 minutes, checking at 50 minutes with a toothpick; it should come out with moist crumbs but no wet batter.
  9. Remove bread from oven and cool in pan on wire rack for 10-15 minutes, then remove from pan and cool completely.
  10. Prepare espresso glaze by whisking powdered sugar, instant espresso powder, hot water, and vanilla extract until smooth and pourable.
  11. Drizzle glaze over cooled bread and let set for about 10 minutes before serving.

Notes

Squeeze zucchini thoroughly to avoid soggy bread. Use room temperature eggs for better mixing. Fold ingredients gently to keep bread tender. Tent with foil if browning too fast after 40 minutes. Espresso powder adds subtle coffee flavor without bitterness. Glaze consistency can be adjusted with more water or powdered sugar.
