Have you ever thought to turn zucchini bread chocolate? This is a seriously easy chocolate bread that is the best way to use up zucchini before it goes bad. The shredded zucchini keeps the bread moist, while the cocoa powder and chocolate chips make it super chocolatey!

Why You’ll Love Chocolate Zucchini Bread

It’s a quick bread recipe – a one bowl zucchini bread with double the chocolate. You don’t taste the zucchini – it’s really there for moisture. The bread freezes perfectly, either as slices or the entire loaf, so it’s great to make ahead. You can use freshly grated zucchini or frozen – so it’s perfect all year long.

Ingredients Needed

  • Vegetable oil: You can also use canola oil or melted coconut oil.
  • Sugars: I like to use a combination of brown sugar and granulated sugar to keep the bread moist.
  • Unsweetened cocoa powder: Regular is best, not dutch processed cocoa.
  • All-purpose flour: Be sure to measure flour correctly.
  • Shredded zucchini: Shred it yourself – there is no need to ring it out.
  • Chocolate chips: Use regular or mini chips! Or trade out the chips for chopped nuts, or use half and half.

Be sure to see the recipe card below for full ingredients & instructions!

Recipe Swap: Gluten Free Bread

Oh, and there’s one more thing to love about this recipe – you can make it gluten-free chocolate zucchini bread. Use your favorite 1:1 gluten-free flour!

How to make Chocolate Zucchini Bread

  1. Combine the oil, both sugars, egg, and vanilla in a large mixing bowl.
  2. Add the cinnamon, baking soda, baking powder, salt, and cocoa powder and mix to combine. You can also whisk the dry ingredients separately.
  3. Stir the flour into the wet ingredients.
  4. Then fold in the zucchini and the chocolate chips and mix.
  5. Pour the batter into the prepared pan and sprinkle chocolate chips over the top. Bake the bread for 45 to 55 minutes.
  6. Cool the chocolate zucchini bread for at least ten minutes before slicing it.

Expert Tips & Variations

  • Add some strawberries or raspberries to make a chocolate version of my blueberry zucchini bread.
  • You can easily turn this into 12 zucchini muffins by lining muffin pans with liners.
  • You don’t want your zucchini to be too wet or it will cause too much moisture in your bread. Normally freshly grated zucchini is just fine, but if you’re using thawed frozen zucchini or your freshly grated seems extra wet, just pat it dry with paper towels.
  • Store at room temperature, wrapped in plastic wrap.
  • You can freeze the whole loaf or freeze slices in sandwich bags.
  • I like to use an 8×4” loaf pan for this recipe because the bread gets a nice dome. You can use a 9×5” loaf pan, but the bread will have a flatter top.

Why did my quick bread fall after baking?

There could be a few reasons why your bread collapsed:

  • Did you measure the ingredients correctly? Too much liquid in the batter can cause the bread to sink in the middle when it cools.
  • Don’t let the batter sit around too long before baking it. As soon as you’ve made it, it’s best to get that loaf into the oven. If the batter sits too long, the leavening agents lose their effectiveness.
  • Did you bake it long enough? If you take the chocolate zucchini bread out of the oven too soon the center will not be done, causing the loaf to sink. So, always do the toothpick test – once it comes out with just a few crumbs, it’s done. If there is batter on it, leave the bread in the oven.

  1. Now I wish that I did have frozen shredded Zucchini in my freezer! Guess I will have to run to the store!

  2. I love zucchini – love the word zucchini: courgette sounds so much less Latin and masculine and charismatic. I wish we had zuchini here in Scotland. I would be all over it. Will just have to make do with courgette though… ;-D It’s a gorgeous looking bread. Fabulous texture and colour. Notice I’m ignoring all mention of Twilight… (Least said, soonest mended.)

  3. I’ve read the books once, but have to admit that I liked them better than the movies (yes, K.S. really bothers me that much). If you’re looking for another series to fall in love with, check out Diana Gabaldon’s Outlander series. It’s a bit of science fiction, a bunch of love story, tons of history and a whole lot of gorgeous Scotsmen rolled in to one fantastic set of books.

    In fact, I think I’ll start reading them again. Can you hand me a slice (or three) of that amazing bread, please?

    1. I need to get the Outlander series. I read the first one and really liked it. I need it on Kindle though. They’re just so heavy, lol!

  4. I need to read the books every so often, too.

    …but I’ll forgive you on liking the movies and not minding K Stew. Cuz I love ya.

    And this bread. I seriously need to start baking with zucchiniiiiii!

  5. That giant chocolate swirl is amazing! Wow oh wow, it is picture perfect and I am loving everything about this bread! Oh and you a going to LOVE Harry Potter! Well, at least I do!

  6. Oh I loved the Harry Potter books (and movies). So so good!! I’m not sci fi either…although since Twilight i find myself loving vampires…and zombies 🙂

  7. I love zucchini bread! Add chocolate to it and it is a match made in heaven! This bread looks wonderful!

  8. That is so me with some series! I don’t want to finish because then its done and then there is nothing else! Its depressing. Which I why I don’t read/watch that series very often:) I totally agree with Averie, you are the queen of breads! Zucchini is one of the best sweet bread ingredients and since there is no oil or butter, definitely qualifies as post workout food. Yes, I do it, too! 🙂

  9. Haha – I’m TOTALLY one of those people! I loved the Twilight series (though, I think the movies can be a little silly) and really, I love lots of young adults books. I just finished Pivot Point, which was good, but nothing to write home about. If you haven’t yet, DON’T read Hush, Hush – it was plugged as another supernatural love story and OMG, it was so awful. Not even awful in a redeeming way. Just awful 😉

    This bread looks amazing!!

  10. You have pumpkin bread, zuke, avocado, banana, and let’s see what other breads can you do..squash? I dunno, you are the bread queen! Ok so me too. I love putting zuke in bread, actually. Makes it so moist and wonderful. I actually have a zuke cake/bars on my site and get complaints on the recipe…that it’s…too moist and soft 🙂 NEVER! Your bread looks the same. Pinned.

    1. I’m kind of addicted to breads. I still need to post the original banana bread, the one that all these others are based on. Kinda funny I’ve never re-done that one!
