How to Make The Best Double Chocolate Zucchini Bread
- Preheat the Oven: Set your oven to 350°F (175°C). Grease an 8.5 x 4.5-inch loaf pan and line it with parchment paper, letting it hang over the sides for easy removal later.
- Whisk Dry Ingredients: In a medium bowl, whisk together the 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 this mixture aside.
- Mix Wet Ingredients: In a large bowl, whisk together the 2 large eggs, 1/3 cup vegetable oil or melted coconut oil, 1/4 cup Greek yogurt, and 1 cup granulated sugar until smooth and thoroughly combined. Then, stir in the 2 teaspoons vanilla extract.
- Incorporate Zucchini: Add in the 2 cups shredded zucchini and mix until it’s well integrated into the wet ingredients.
- Combine Wet and Dry: Gradually fold the dry mixture into the wet mixture, mixing until just combined. Be careful not to overmix; a few lumps are okay!
- Add Chocolate Chips: Gently fold in the 1 cup semisweet chocolate chips, ensuring they are evenly distributed throughout the batter.
- Pour and Smooth: Pour the batter into your prepared loaf pan, smoothing the top with a spatula. Sprinkle the 3/4 cup chopped dark chocolate on top for an extra touch of indulgence.
- Bake: Place in the oven and bake for about 55 to 70 minutes. Start checking for doneness at 55 minutes; insert a toothpick into the center—it should come out with a few moist crumbs.
- Cool the Bread: Allow your bread to cool in the pan for about 15 minutes. Then, use the parchment paper overhang to lift it out and transfer it to a wire rack to cool completely.
- Slice and Enjoy: Once cooled, slice into delicious pieces and delight in the extra chocolatey, extra fudgy goodness of your double chocolate zucchini bread!
Storing & Reheating
Store your double chocolate zucchini bread at room temperature in an airtight container for up to four days. If you prefer a longer shelf life, refrigerate it for up to a week. For freezing, wrap the cooled bread securely in plastic wrap and then aluminum foil to preserve it for up to three months. To enjoy it warm, simply reheat in a toaster oven or microwave for a few seconds, allowing you to experience that delightful fresh-baked texture again. Keep in mind that the texture might change slightly after freezing, but a quick warming will refresh its delightful chew!
Chef’s Helpful Tips
- To achieve the perfect moisture balance, make sure your shredded zucchini is well-measured. Too little can lead to dry bread, while too much may impact the structure.
- For a richer flavor, consider using dark chocolate chips or a mix of semisweet and bittersweet chocolate.
- Make sure to let your bread cool completely before slicing. This helps set the structure and ensures cleaner cuts.
- If the top of the bread browns too quickly, you can lightly cover it with aluminum foil halfway through baking.
- Feel free to customize by adding nuts or dried fruit for a fun texture twist.
You now have the tried-and-true recipe for an absolutely luscious treat that will satisfy any chocolate craving. Don’t hesitate to make it your own—experiment with various types of chocolate or sneak in a few nuts for crunch.

Recipe FAQs
Can I substitute the eggs in this recipe?
Absolutely! You can use flax eggs or applesauce as egg replacements. To make a flax egg, mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water. Allow it to sit until it thickens. For applesauce, use 1/4 cup per egg.
How do I know if my zucchini bread is done?
The best way to check for doneness is by inserting a toothpick into the center of the loaf. If it comes out with just a few moist crumbs, your bread is perfectly baked. If there’s wet batter, give it more time in the oven.
Can I make this zucchini bread gluten-free?
Definitely! Substitute the all-purpose flour with a gluten-free flour blend. Make sure to choose one that has xanthan gum; this will help the bread hold its structure.
How do I store leftover zucchini bread?
