Chocolate Zucchini Bread
This post may contain affiliate links. Read my full disclosure policy.
Rich, deeply chocolaty, and incredibly moist, this chocolate zucchini bread tastes more like chocolate cake than vegetable bread. It’s easy to make with simple pantry ingredients, freezes beautifully, and is the perfect way to use up summer zucchini.
Every summer, when zucchini starts taking over the garden, I make at least one loaf of this chocolate zucchini bread. It’s one of those recipes that surprises people because, despite containing two whole cups of shredded zucchini, it doesn’t taste even remotely like vegetables. The zucchini simply melts into the batter as it bakes, creating an incredibly moist, tender loaf with an intense chocolate flavor.
Enjoy it as an afternoon snack, dessert, or even breakfast with a cup of coffee. And if you’re looking for more sweet ways to use up zucchini, don’t miss my classic zucchini bread and chocolate chip zucchini muffins. If you love chocolate quick breads, my chocolate banana bread is another reader favorite.
“This was ridiculously delicious! Moist and deeply chocolatey, using dutch processed cocoa plus espresso powder made a huge difference.”
What you’ll need to make Chocolate zucchini Bread
- All-purpose flour: Provides structure while keeping the loaf tender.
- Dutch-process cocoa powder: Gives the bread a deep chocolate flavor and rich dark color. Natural cocoa powder works, too, if that’s what you have on hand.
- Brown sugar: Adds sweetness along with a subtle caramel flavor that pairs beautifully with the chocolate.
- Butter: Melted butter keeps the recipe simple while adding richness and flavor.
- Eggs: Add structure and moisture.
- Baking powder and baking soda: Working together, they help the loaf rise evenly.
- Espresso powder (optional): You won’t taste coffee—it simply deepens the chocolate flavor.
- Zucchini: You’ll need about two medium zucchini. There’s no need to peel them or squeeze out the moisture—the zucchini’s natural moisture is what keeps the bread so tender.
- Chocolate chips: Folded into the batter for pockets of melted chocolate in every slice.

Step-by-Step Instructions
Step 1: Shred the zucchini. I use a food processor as it’s a bit quicker, but you can also do it by hand with a box grater.
Step 2: Combine the wet ingredients. Melt the butter in a large mixing bowl and mix in the brown sugar. Once combined, stir in the eggs and vanilla.
Pro tip: It’s important to stir the brown sugar into the melted butter before adding the eggs, as the hot butter alone could cook the eggs.
Step 3: Combine the dry ingredients. Next, combine the flour, cocoa powder, baking soda, baking powder and salt in a mixing bowl. Whisk to combine.
Step 4: Mix the batter. Combine the egg mixture with the flour mixture and stir to combine—the mixture will be quite thick. Next, mix in the grated zucchini and chocolate chips.
Step 5: Bake and cool. Transfer the batter to a greased loaf pan, and spread the batter evenly with a spatula. Bake for about an hour, then let the loaf cool in the pan for about ten minutes, then turn the loaf out onto a rack to cool completely. It’s delicious right out of the oven but it’s best to wait at least an hour to slice it, otherwise it may crumble a little. Enjoy!

Chocolate Zucchini Bread
Ingredients
- ½ cup (1 stick) unsalted butter
- ¾ cup + 2 tablespoons (packed) light brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1⅔ cups all-purpose flour, spooned into measuring cup and leveled-off
- ⅓ cup Dutch-process cocoa powder (ok to substitute natural cocoa powder)
- ¾ teaspoon salt
- ½ teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon espresso powder or instant coffee (optional)
- 2 cups shredded zucchini, gently packed (you'll need about 2 medium zucchini; do not wring out the liquid)
- 1 cup semi-sweet chocolate chips
Instructions
- Preheat the oven to 350°F (175°C) degrees and grease an 8½ x 4½-in (22 x 11-cm) loaf pan with nonstick cooking spray.
- Place the butter in a large microwave-safe mixing bowl and microwave for one minute, or until just melted. Stir in the brown sugar until completely smooth. Add the eggs and vanilla and stir until incorporated. (Be sure to add the eggs after the brown sugar is mixed in, as the hot butter alone could cook the eggs.)
- Whisk together the flour, cocoa powder, salt, baking powder, baking soda and instant coffee (if using) in a medium bowl. Add to the butter mixture and stir until well combined. It will be very thick.
- Stir in the shredded zucchini and chocolate chips. (It will still be thick -- that's okay.)
- Spoon the batter into the prepared loaf pan and spread evenly. Bake for 60 to 65 minutes, or until a toothpick or cake tester inserted into the center comes out clean (save for perhaps a smear from the melted chocolate chips). Let the loaf cool on a rack for about 10 minutes before turning out onto a rack to cool completely.

All I can say is ymmm…
My 15yr old is extremely picky and not a fan of vegetables but this bread he gobbled it down with a big glass of milk.
Made this delicious moist Chcolate Zucchini Bread yesterday. I added 1/2 cup chopped walnuts and 1 teaspoon cinamon. This is the best Chocate Zucchini bread I’ve made so far. Thank you so much for the recipe.
Made this but split it into 2 loaves (same size pans) and cooked for 40 minutes. So delicious!!! Especially warm from the oven!
This Chocolate Zucchini Bread was the best I’ve ever made! It turned out just like the picture in the recipe and it was so moist and chocolatey I couldn’t believe it. In all honesty, it tastes like a scrumptious chocolate cake. We love it so much I have a second one baking in the oven right now! You cannot go wrong with this recipe!
My boys were so angry that this contained Zucchini, until they tasted it. Loaf gone in 45 minutes (they are 14 and 15…) Chocolatey, moist and scrumptious-will be making it again very soon!
Super chocolately and moist! This is a wonderful recipe for the chocolate lover in your family!
Just made your recipe for the first time. Although I am a chocolate lover I found this a little too sweet. Will make it again without the chocolate chips which were semi-sweet or perhaps just 1/4 cup of chips. I have a chocolate zucchini cake recipe I make all the time and it only uses 1/4 cup of chocolate chips. Will also look for the bittersweet chips the next time I am shopping. Very easy recipe to follow.👍
Hi Jenn,
I don’t get bittersweet chocolate chips where I live so was wondering if there was anything else I could substitute for the chips?
Thanks!

Hi Niyati, you could also use semi-sweet or milk chocolate chips here. Hope you enjoy!
The bread came out moist and delicious. Everyone who screwed up their nose at the thought of zucchini bread had to eat their words along with a slice of the cake. This is one I’ll be making again.
Mine turned out quite dry and I followed the recipe as is. Baked at 60 minutes no more and most of my loaves take longer than stated recipe cook times so I know its not my oven.
I’ve made this recipe many times and it’s never turned out dry for me. I’m wondering if it’s your flour? Storing it in airtight containers can sometimes affect recipes. I’ve had that experience before.
Excellent recipe, made this a couple times now and it is a keeper
I’m not a baker by any means, but curious – recipe says to microwave butter instead of beating it, why is that exactly?
Thanks for another great recipe!
Hi Ivan, glad you like it! Not all baking recipes require creaming the butter and sugar. This one just works better with melted butter.
