Ingredients

Scale
  • 2 cups (240 g) all-purpose flour
  • 3/4 cup (75 g) unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 cup (200 g) granulated sugar
  • 1/2 cup (120 ml) vegetable oil
  • 2 large eggs, room temperature
  • 1/2 cup (120 g) sour cream
  • 1 teaspoon vanilla extract
  • About 2 cups grated zucchini (roughly 2 medium zucchinis), squeezed lightly
  • 1 cup (175 g) semi-sweet chocolate chips
  • Optional: 1/2 cup (60 g) chopped walnuts or pecans

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×5 inch loaf pan or line with parchment paper.
  2. Wash and dry zucchinis. Shred finely using a box grater or food processor. Place shredded zucchini in a clean towel and squeeze out excess moisture.
  3. In a large bowl, whisk together flour, cocoa powder, baking soda, baking powder, and salt until evenly combined.
  4. In another bowl, whisk sugar, vegetable oil, and eggs until smooth and slightly pale. Add sour cream and vanilla extract, mixing until blended.
  5. Slowly add dry ingredients to wet ingredients, stirring gently with a spatula until just combined. Fold in shredded zucchini and chocolate chips. If using nuts, fold them in now.
  6. Pour batter into prepared loaf pan and smooth the top.
  7. Bake for 55-65 minutes, checking at 50 minutes with a toothpick. It should come out with a few moist crumbs but no wet batter. Edges will pull slightly away from the pan.
  8. Cool bread in pan for 15 minutes, then transfer to a cooling rack to cool completely before slicing.

Notes

Drain zucchini well to avoid soggy bread. Use room temperature eggs and sour cream for better mixing and rise. Avoid overmixing to keep bread tender. Tent with foil if browning too fast. Let bread cool completely before slicing to prevent gummy texture. Optional nuts add crunch. For gluten-free, use 1:1 gluten-free flour blend with xanthan gum. Vegan adaptations include flax eggs and coconut yogurt.
