You'll love this chocolate zucchini bread recipe! Packed with shredded zucchini and gooey chocolate chips, it's moist, fudgy, and delicious.
This double chocolate zucchini bread is moist, fudgy, and delicious. In the summertime, it’s my favorite way to satisfy a chocolate craving. It tastes just as decadent as a rich chocolate cake, but it’s made with healthier ingredients like whole wheat flour, maple syrup, and zucchini. Eating your vegetables has never tasted so good!
Like my classic zucchini bread recipe, this recipe makes two loaves. They disappear pretty quickly in our house, but if you have extra, pop one loaf in the freezer for another day, or share it with a friend! They (and you) will love this chocolate zucchini bread.
Chocolate Zucchini Bread Ingredients
Here’s what you’ll need to make this double chocolate zucchini bread:
- Flour – I use a mix of all-purpose flour and whole wheat flour. They give the bread a perfect moist crumb, plus a little whole grain power.
- Unsweetened cocoa powder – It adds rich chocolate flavor to the batter.
- Baking powder, baking soda, and eggs – They help the bread puff up as it bakes.
- Maple syrup – Many chocolate zucchini bread recipes call for granulated sugar or brown sugar. I sweeten mine with maple syrup instead. It adds a subtle caramel-like flavor that I love.
- Almond milk – For moisture. Oat milk, regular milk, and soy milk would all work well here too.
- Vegetable oil or coconut oil – For moisture and richness.
- Cinnamon, nutmeg, and vanilla extract – For warm depth of flavor.
- Zucchini – I grate mine on the largest holes of a box grater to get the best moist, zucchini-flecked texture!
- Chocolate chips – You’ll fold some into the batter to add fudginess to the inside of the loaf. Then, you’ll sprinkle more on top.
- And sea salt – To make all the flavors pop!

How to Make Chocolate Zucchini Bread
This double chocolate zucchini bread recipe couldn’t be simpler to make! Here’s how it goes:
First, whisk together the dry ingredients in one bowl and the wet ingredients in another. Add the dry ingredients to the wet ingredients, and gently stir to combine.
Fold in the chocolate chips. Look how chocolatey that batter is!!
Pour the batter into two greased loaf pans. Bake at 350°F until a toothpick inserted into the center of the loaves comes out clean.
Place the pans on a wire rack, and allow the loaves to cool in the pan before digging in. So easy!
Chocolate Zucchini Bread Recipe Tips
- Be careful not to overmix! As with all baking recipes that use wheat flour, overmixing the batter will make the bread dense. Stir until everything is just combined to get soft, moist, and puffy loaves.
- Bake once, eat twice. This recipe makes two loaves of quick bread. They’ll keep well in an airtight container at room temperature for up to 3 days, but they also freeze perfectly. I like to enjoy one right away and slice and freeze the other. To thaw a slice, let it sit out at room temperature for an hour or so, or pop it in the microwave for around 30 seconds.
- Try changing it up! Swap half the chocolate chips for chopped walnuts, pecans, or dried tart cherries. Or, if you have it on hand, use yellow squash in place of the zucchini. Let me know what variations you try!
FAQs
Should you leave the skin on the zucchini when you make this chocolate zucchini bread?
I never peel zucchini when I make zucchini bread. The skin doesn’t affect the bread’s flavor, so I see peeling the zucchini as an unnecessary extra step.
Do you squeeze out the liquid from zucchini for bread?
Nope! While some zucchini bread recipes might ask you to squeeze out the zucchini’s excess moisture, I never will. Zucchini’s magic is that it makes baked goods super moist. We want all the moisture inside it to go into the bread! Simply grate the zucchini on the large holes of a box grater and add it straight to the batter.

So glad you loved it, Mary!
Hi, I don’t have any maple syrup on hand. Is it possible to substitute honey? Thank you.
Have you ever tried substituting green(underripe) butternut squash for zucchini? I’m looking for a recipe to use some of the butternut that will not have anywhere enough time to ripen before frost. My concern is that it may not have as high of a moisture content as zucchini but flavor should be the same.
Hi Pat, wow, great question! I’ve never cooked with green butternut squash, so I’m not sure how it would work here. It does likely have less moisture than zucchini. If you try it, you could loosen the batter with 1/4 to 1/2 cup milk if needed.
Can you substitute any of the flours for oat flour? I am already planning to substitute the all purpose for a gluten free flour, but I’m always hoping to minimize the amount of GF flour because it’s somewhat nutritionally void. Any advice and measurements are appreciated! Thanks!
Hi Sarah, I wouldn’t recommend using oat flour here. We’ve tested it in many baking recipes over the years and have never found it to be a great 1 to 1 substitute for another type of flour. I haven’t tried this, but using part almond flour or buckwheat flour might work. I’d start with 2 cups GF flour and 1/2 cup almond or buckwheat and see how that goes. Hope this helps!
Should I strain the shredded zucchini or keep all the moisture from the zucchini?
Hi Genny, no need to strain or squeeze! The moisture from the zucchini makes this bread super moist.
Hi, I don’t have 2 8×4” loaf pans, I just have one that’s a bit bigger – it’s 12×4. Would you recommend I just cut everything by a third? Thanks!
Hi Eva, hmmm yes, the math might be tricky, but reducing the recipe by a third or a quarter should yield a good-sized loaf in a 12×4″ pan.
Thank you!!! I had ChatGPT re-calculate the amounts and it turned out perfectly moist and not too sweet – absolutely delicious! 🙂
You can mould few layers of foil inside larger pan and shape it to size you want that’s what I do when I don’t have correct size pans grease it then discard when unneeded less washing up:)
Or…use the additional batter to make a few muffins.
This looks delicious! Could I substitute the coconut oil for something else like olive oil or butter, or is it completely necessary? Thanks 🙂
Hi Anna, you could use melted butter or vegetable oil instead.
Is there nutritional information available for the recipes?
Hi Marge, we don’t calculate nutrition facts for our recipes unfortunately, but you could use an online nutrition calculator to get an estimate.
I made this recipe but used stevia milk chocolate chips and White chocolate chips. I put one cup of pecans in this recipe and put white chocolate chips on top and it turned out great. Love this recipe.
Sounds delicious, Barbara! I’m so glad you enjoyed the recipe.
Can I do this same recipe as muffins? 🙂
Hi Whitney, you could! I think it would make about 15-18 muffins. I’d start checking them after 15 minutes in the oven, though they could take up to 20. Hope you enjoy!
I love this recipe! My daughter discovered it and I’ve made it three times in the past month. And sent it to friends who also love it. It is my new go to zucchini recipe. Thank you!
What are the nutritional values?
My loaves stuck so badly to my pans that I can’t send the bread as a birthday treat to my granddaughter.
Satisfied my chocolate craving and sweet tooth! Preferred it heated up for chocolatey goodness. … 1 slice. 214 calories. (8g F/33g C/ 4g P) I followed the recipe exactly and calculated macros in MyFitnessPal.
Hi, I tried this recipe for the first time the other day and was very disappointed as the loaves fell after they came out of the oven. I did add walnuts along with the chocolate chips, but the only thing I really can think of is maybe it was the cocoa powder. The recipe did not specify natural or processed Dutch cocoa, so I used what I had – the Dutch processed cocoa powder. I previously read that it makes a difference between the two because of the chemistry of the baking powder and baking soda from one kind of cocoa to another.
Hi Elle, it may have been that the loaves needed an extra few minutes in the oven. They can sometimes fall when they’re slightly underbaked. Because this recipe has both baking soda and baking powder, I don’t think the cocoa powder would have made the difference.
