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
- Preheat and prepare the pan: Preheat your oven to 350°F (177°C). Grease a 9×5-inch loaf pan or an 8×4-inch loaf pan for a taller loaf using nonstick spray. Set the pan aside.
- Combine dry ingredients: In a large mixing bowl, whisk together the all-purpose flour, unsweetened natural cocoa powder, baking soda, baking powder, salt, and espresso powder until fully combined. Stir in the semi-sweet chocolate chips evenly. Set aside.
- Mix wet ingredients: In a separate medium bowl, whisk the eggs, vegetable oil (or melted coconut oil), Greek yogurt (or sour cream), granulated sugar, and pure vanilla extract until smooth and thoroughly combined.
- Combine wet and dry mixtures: Slowly pour the wet ingredient mixture into the dry ingredients. Gently whisk to combine until just blended—avoid overmixing. Fold in the shredded zucchini carefully. Expect a very thick batter.
- Bake the bread: Pour the batter evenly into the prepared loaf pan. Bake for 45 to 55 minutes. To prevent over-browning, loosely cover the bread with aluminum foil halfway through baking. The 9×5-inch pan requires closer to 45 minutes, while the 8×4-inch pan needs around 55 minutes. Begin checking doneness around 45 minutes by inserting a toothpick into the center; it should come out clean or with a few small moist crumbs.
- Cool the bread: Remove the bread from the oven and let it cool in the pan set on a wire rack for 1 hour. While still warm, optionally press a few extra chocolate chips gently into the top for decoration.
- Finish cooling and store: Remove the bread from the pan and place it directly on the wire rack to cool completely. Store the bread covered at room temperature for up to 5 days or refrigerate for up to 1 week.
Notes
- Freezing Instructions: Freeze the fully baked and cooled loaf, tightly wrapped, for up to 3 months. Thaw overnight in the refrigerator. Optionally warm to room temperature before serving.
- Special Tools: 9×5-inch or 8×4-inch loaf pan, box grater, glass mixing bowls, whisk, silicone spatula, cooling rack.
- Doubling the Recipe: Double all ingredients and divide the batter between two loaf pans. If batter is too thick, add a splash of milk.
- Chocolate Zucchini Muffins: Preheat oven to 425°F (218°C), spray a 12-count pan or use liners. Fill liners to top with batter, bake 5 minutes at 425°F, then reduce oven to 350°F (177°C) and bake 14–15 more minutes.
- Chocolate Zucchini Cupcakes: Preheat oven to 350°F (177°C), line a 12-count pan. Fill liners 2/3 full with batter and bake 19–20 minutes. Cool and frost with chocolate buttercream if desired.
- Cocoa Powder: Use natural cocoa powder, not Dutch-process for best flavor.
- Espresso Powder: Enhances chocolate flavor; can be substituted with instant coffee powder or omitted.
- Chocolate Chips: Essential for sweetness and texture, do not omit.
- Yogurt: Nonfat plain Greek yogurt is recommended, but full-fat, low-fat, vanilla, regular plain yogurt, or sour cream work well.
- Sugar: Use 2/3 cup (135g) granulated sugar; for a sweeter bread, increase to 3/4 cup (150g).
- Zucchini: No need to peel before shredding; one medium zucchini equals about 1.5 cups shredded. If using frozen zucchini, thaw and blot excess moisture.
