The beautiful dark chocolate color and rich aroma make it impossible to believe there are vegetables hiding inside.

Whether you’re looking for a way to use up garden zucchini, want a dessert that feels a little less guilty, or simply love the combination of chocolate and super-moist quick bread, this double chocolate zucchini bread delivers on every front. It’s perfect for breakfast with coffee, afternoon tea, or even dessert with a scoop of vanilla ice cream.

Ingredients

For the Wet Base:

• 1 cup melted unsalted butter or vegetable oil, plus more for pan
• 1½ cups grated zucchini (from 1 large zucchini)
• 1¼ cups sugar
• 3 large eggs, room temperature
• 1 teaspoon pure vanilla extract

For the Dry Chocolate Mix:

• 1½ cups all-purpose flour
• ⅓ cup unsweetened cocoa powder (preferably Dutch-process)
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• 1 teaspoon salt

For Extra Chocolate Goodness:

• ¾ cup semisweet chocolate chips

Instructions

1. Prepare Your Baking Environment Preheat your oven to 350 degrees Fahrenheit and position a rack in the center for even baking. Lightly grease a 9-inch loaf pan with butter, vegetable oil, or cooking spray, making sure to coat all surfaces thoroughly. Line the pan with parchment paper, leaving generous overhang on the long sides – this creates handles that make removing your double chocolate zucchini bread effortless once it’s baked. The parchment paper is essential for this recipe because the chocolate can stick to the pan.

2. Create the Perfect Dry Ingredient Blend In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt until everything is evenly distributed and there are no lumps of cocoa powder visible. The Dutch-process cocoa powder creates the richest, most intense chocolate flavor in your double chocolate zucchini bread, but regular unsweetened cocoa works beautifully too. This dry mixture is the foundation that will give your bread its tender structure and deep chocolate taste.

3. Prepare Your Zucchini Foundation Grate your zucchini using the largest holes of a box grater – you want substantial shreds that will distribute moisture throughout your double chocolate zucchini bread. Don’t worry about peeling the zucchini; the skin adds nutrients and completely disappears in the finished bread. You don’t need to squeeze out the moisture from the zucchini – that liquid is exactly what makes this bread incredibly moist and tender.

4. Combine the Wet Ingredients In a large mixing bowl, combine the grated zucchini, sugar, eggs, melted butter or oil, and vanilla extract. Whisk everything together until well combined and the mixture looks smooth and unified. Here’s a little trick for the best double chocolate zucchini bread – make sure your melted butter has cooled slightly so it doesn’t cook the eggs when you mix them together. The sugar should be completely incorporated, and the eggs should be evenly distributed throughout.

5. Fold in the Dry Ingredients Add the flour and cocoa mixture to your wet ingredients and stir gently with a wooden spoon or rubber spatula until just combined. The key word here is “just” – overmixing develops gluten and can make your double chocolate zucchini bread tough instead of tender. You want to see the mixture come together into a cohesive batter with no dry flour visible, but stop as soon as that happens.

6. Add the Chocolate Chip Magic Fold in the chocolate chips, distributing them evenly throughout the batter. These chips create pockets of melted chocolate goodness that make every bite of your double chocolate zucchini bread a delightful surprise. Reserve a few chips to sprinkle on top of the batter for an extra beautiful presentation.

7. Bake to Chocolate Perfection Pour the batter into your prepared loaf pan, spreading it evenly with a spatula. The batter will be thick but pourable. Bake for approximately 1 hour, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs clinging to it. Your kitchen will smell absolutely incredible as this double chocolate zucchini bread bakes – that rich chocolate aroma is one of life’s simple pleasures.

8. Cool for Perfect Texture Allow the bread to cool in the pan for exactly 15 minutes – this prevents it from falling apart when you remove it. After 15 minutes, use the parchment paper handles to lift the loaf out of the pan and transfer it to a wire cooling rack. Let it cool completely before slicing. This cooling time allows the structure to set properly and makes slicing much easier.

Tips & Variations

Zucchini Preparation: Don’t squeeze the moisture out of your grated zucchini – that liquid is what makes this bread so incredibly moist. One large zucchini usually yields about 1½ cups grated.

Cocoa Powder Choice: Dutch-process cocoa creates a richer, more mellow chocolate flavor, while natural cocoa powder provides a more intense, slightly acidic chocolate taste. Both work beautifully.

Oil vs. Butter: Vegetable oil creates a more tender crumb and keeps longer, while butter adds richness and flavor. Choose based on your preference.

Storage Success: This double chocolate zucchini bread actually improves after a day wrapped in plastic wrap. Store in the refrigerator for up to a week or freeze for up to 3 months.

Chocolate Variations: Try white chocolate chips, dark chocolate chunks, or even a combination of different chocolates for variety.

Add-In Options: Chopped walnuts or pecans add wonderful texture and complement the chocolate beautifully.

Mini Loaf Magic: Divide the batter among 4 mini loaf pans and reduce baking time to 35-40 minutes for perfect gift-sized portions.

The Secret Behind Perfect Chocolate Zucchini Bread

What makes this double chocolate zucchini bread so exceptionally moist and tender is understanding how zucchini functions in baking. The vegetable’s high water content keeps the bread incredibly moist, while its mild flavor completely disappears, leaving only the benefits of added nutrition and perfect texture.

The combination of both baking soda and baking powder creates the ideal rise and crumb structure. The baking soda reacts with the acidity in the cocoa powder, while the baking powder provides additional lift, resulting in a bread that’s dense enough to be satisfying but light enough to not feel heavy.

The melted butter or oil is crucial for creating that tender crumb that makes each slice of double chocolate zucchini bread so irresistible. Unlike creamed butter, melted fat coats the flour proteins differently, resulting in a more tender final product.

Why This Recipe Works So Well

This double chocolate zucchini bread recipe has been perfected through countless batches to achieve the ideal balance of moisture, chocolate flavor, and texture. The ratio of wet to dry ingredients creates a batter that’s substantial enough to support the chocolate chips without being so thick that it doesn’t bake evenly.

The addition of both cocoa powder and chocolate chips provides layers of chocolate flavor – the cocoa powder infuses the entire bread with chocolate taste, while the chips provide bursts of intense chocolate in every bite. This double chocolate approach is what sets this recipe apart from ordinary zucchini bread.

Perfect for Every Season

While this double chocolate zucchini bread is perfect for using up summer’s zucchini abundance, it’s delicious any time of year. Frozen grated zucchini works just as well as fresh, making this a year-round treat. The rich chocolate flavor makes it perfect for fall and winter when you crave something warm and comforting.

This bread is incredibly versatile – serve it for breakfast with coffee, pack it in lunch boxes, bring it to potlucks, or serve it warm with ice cream for dessert. The fact that it contains vegetables makes it feel a little less indulgent, even though it tastes like pure chocolate decadence.

Final Thoughts

This double chocolate zucchini bread has become one of my most beloved recipes, and I hope it brings the same joy to your kitchen. There’s something so satisfying about creating something that tastes like dessert while sneaking in extra nutrition – it’s the best of both worlds.
