Ingredients You’ll Need
- 1 1/2 cups all-purpose flour: This provides the structure for the bread. If you prefer a gluten-free version, you can substitute with a 1:1 gluten-free flour blend.
- 1/2 cup unsweetened cocoa powder: Opt for a high-quality cocoa for the best depth of flavor without added sugar.
- 1 teaspoon baking soda: This helps the bread rise and gives it that light texture.
- 1/2 teaspoon baking powder: Works alongside baking soda to ensure the bread rises beautifully.
- 1/2 teaspoon salt: Balances the sweetness and enhances all the other flavors in the bread.
- 1 teaspoon espresso powder (optional): It may seem strange, but espresso powder intensifies the chocolate flavor without adding any coffee taste.
- 2 large eggs: They bind everything together and lend moisture, making the bread tender.
- 1/3 cup vegetable oil or melted coconut oil: Oil keeps the bread moist; coconut oil offers a hint of coconut flavor.
- 1/4 cup Greek yogurt or sour cream: Adds extra moisture and helps with that super soft texture.
- 1 cup granulated sugar: Sweetens the bread without overwhelming it.
- 2 teaspoons vanilla extract: Freshens the flavor and enhances the sweetness.
- 2 cups shredded zucchini (about 2 medium zucchinis; no need to blot): Zucchini adds moisture without altering the flavor, making this a fantastic way to sneak in veggies.
- 1 cup semisweet chocolate chips: Melts into beautiful, gooey pockets of chocolate throughout the bread.
- 3/4 cup chopped dark chocolate or more semi-sweet chocolate chips for topping: This adds an extra chocolatey finish; feel free to load up!
How to Make The Best Double Chocolate Zucchini Bread
- Preheat the Oven: Set your oven to 350°F. Grease an 8.5 x 4.5-inch loaf pan and line it with parchment paper, leaving some overhang for easy removal.
- Whisk Dry Ingredients: In a medium bowl, whisk together 1 1/2 cups all-purpose flour, 1/2 cup unsweetened cocoa powder, 1 teaspoon baking soda, 1/2 teaspoon baking powder, 1/2 teaspoon salt, and 1 teaspoon espresso powder (if using). Set the dry ingredients aside.
- Mix Wet Ingredients: In a large bowl, whisk together 2 large eggs, 1/3 cup vegetable oil (or melted coconut oil), 1/4 cup Greek yogurt (or sour cream), 1 cup granulated sugar, and 2 teaspoons vanilla extract until you have a smooth mixture.
- Incorporate Zucchini: Stir in the 2 cups shredded zucchini into the wet mixture until well combined.
- Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix; it’s okay if a few lumps remain.
- Fold in Chocolate Chips: Gently fold in 1 cup semisweet chocolate chips, ensuring they are evenly distributed throughout the batter.
- Transfer to Pan: Pour the batter into your prepared loaf pan, smoothing the top. Sprinkle the 3/4 cup chopped dark chocolate on top for an extra chocolaty treat.
- Bake: Bake for 55 to 70 minutes, checking for doneness starting at 55 minutes. The bread is done when a toothpick inserted into the center comes out with just a few moist crumbs, and the top looks set and slightly cracked.
- Cool: Allow the bread to cool in the pan for about 15 minutes. Then, carefully use the parchment paper overhang to lift it out of the pan and place it on a wire rack to cool completely.
- Slice & Enjoy: Once cool, slice the loaf and indulge in your extra chocolatey, extra fudgy double chocolate zucchini bread!
Storing & Reheating
Once your double chocolate zucchini bread has cooled completely, you can store it at room temperature in an airtight container for up to 2 days. For longer storage, pop it in the refrigerator, where it’s good for about a week. If you want to keep it for an extended period, freeze the bread (wrapped tightly) for up to 3 months. To enjoy, simply reheat in the microwave for about 20 seconds or until warmed through, but note that the texture may change slightly. A quick zap will have it tasting as good as freshly baked.
Chef’s Helpful Tips
- Avoid overmixing the batter, as it can create a dense loaf instead of the tender texture we want.
- Make sure your eggs are at room temperature so they blend better with the other wet ingredients.
- If you have leftover zucchini or are looking to make multiple loaves, this bread stores wonderfully in the freezer for easy future enjoyment.
- Feel free to experiment with chocolate varieties; using a mix of semisweet and milk chocolate chips can add delightful complexity.
- If your batter seems too thick, you can add a splash of milk to reach your desired consistency.
As you step into your baking adventure, remember that this recipe not only rewards you with an irresistible treat but also encourages creativity. Feel free to play around with added spices or even nuts for an extra crunch. I can’t wait for you to try this chocolatey goodness!

Recipe FAQs
Can I make this bread gluten-free?
Yes! Simply replace all-purpose flour with a gluten-free 1:1 baking flour. It maintains the texture and moisture, ensuring your double chocolate zucchini bread remains delicious.
How do I know when the zucchini bread is done baking?
The best way to check for doneness is to insert a toothpick into the center of the loaf. If it comes out with just a few moist crumbs attached, it’s perfect. If there’s wet batter on it, give it more time in the oven.
Can I reduce the sugar in this recipe?
Absolutely! Feel free to reduce the granulated sugar slightly, but keep in mind that this may affect the moistness and overall flavor. You can start by cutting back by 1/4 cup and see how it turns out.
What can I substitute for eggs?
If you’re looking to make this egg-free, you can use flax eggs—simply mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water and let it sit for about 5 minutes until gelatinous. This works well in achieving the same binding effect.
