Ingredients

Units Scale

Dry Ingredients

  • 1 cup (125g) all-purpose flour (spooned & leveled)
  • 1/2 cup (41g) unsweetened natural cocoa powder (not Dutch process)
  • 3/4 teaspoon baking soda
  • 1/4 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/2 teaspoon espresso powder
  • 3/4 cup (135g) semi-sweet chocolate chips

Wet Ingredients

  • 2 large eggs
  • 1/4 cup (60ml) vegetable oil or melted coconut oil
  • 1/3 cup (80g) plain Greek yogurt or sour cream
  • 2/3 cup (135g) granulated sugar
  • 1 teaspoon pure vanilla extract
  • 1 and 1/2 cups (180g) shredded zucchini (no need to blot)

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (177°C). Grease a 9×5-inch or 8×4-inch loaf pan with nonstick spray to prevent sticking, and set aside.
  2. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, natural cocoa powder, baking soda, baking powder, salt, and espresso powder until fully combined. Stir in the semi-sweet chocolate chips to distribute evenly. Set aside.
  3. Combine Wet Ingredients: In a medium bowl, whisk the eggs, vegetable or coconut oil, plain Greek yogurt, granulated sugar, and vanilla extract until smooth and well incorporated.
  4. Combine Wet and Dry Mixtures: Slowly pour the wet mixture into the dry ingredient bowl. Gently whisk until just combined without over-mixing to avoid a tough bread. The batter will be thick.
  5. Fold in Zucchini: Carefully fold the shredded zucchini into the batter until evenly distributed.
  6. Bake the Bread: Pour the batter into the prepared loaf pan. Bake in the preheated oven for 45–55 minutes. Halfway through baking, loosely cover the top with aluminum foil to prevent over-browning. The smaller 9×5-inch pan will bake closer to 45 minutes, while the taller 8×4-inch pan may require up to 55 minutes. Check doneness by inserting a toothpick; it should come out clean with a few moist crumbs.
  7. Cool the Bread: Remove the bread from the oven and let it cool in the pan on a wire rack for 1 hour. While warm, optionally press a few extra chocolate chips on top for appearance.
  8. Remove from Pan and Serve: Carefully take the loaf out of the pan and place on the wire rack to cool completely before slicing.
  9. Storage: Store the bread covered at room temperature for up to 5 days or in the refrigerator for up to 1 week. For longer storage, freeze tightly wrapped for up to 3 months and thaw in the refrigerator overnight.

Notes

  • Freezing Instructions: Freeze baked and cooled loaf tightly wrapped for up to 3 months. Thaw overnight in the refrigerator before serving.
  • Special Tools: Recommended are a 9×5-inch or 8×4-inch loaf pan, box grater for shredding zucchini, glass mixing bowls, a whisk, silicone spatula, and cooling rack.
  • Doubling Recipe: Double all ingredients and divide batter between two loaf pans. If too thick, add a splash of milk.
  • Chocolate Zucchini Muffins: Bake at 425°F (218°C) for 5 minutes then lower to 350°F (177°C) and bake 14–15 minutes more. Makes 10–12 muffins.
  • Chocolate Zucchini Cupcakes: Fill liners 2/3 full and bake at 350°F (177°C) for 19–20 minutes. Frost as desired. Makes 12 cupcakes.
  • Cocoa Powder: Use natural cocoa powder, not Dutch-process, for best flavor.
  • Espresso Powder: Enhances chocolate flavor; can substitute 1 tsp instant coffee powder or omit.
  • Chocolate Chips: Essential for added sweetness and chocolate bursts.
  • Yogurt: Nonfat plain Greek yogurt is preferred; any plain yogurt or sour cream works.
  • Sugar: Adjust sweetness with up to 3/4 cup (150g) if desired.
  • Zucchini: No need to peel before shredding. Use a medium zucchini or about 1½ cups shredded.
