I’ve got a question for you! What does zucchini bread taste like? You probably didn’t answer zucchini.
Like pumpkin bread, zucchini bread is based on a bland, watery vegetable*. (Yes, pumpkin is rather bland. Don’t believe me? Try a spoonful of pumpkin the next time you open a can.)
*Fun fact: botanically speaking, both pumpkin and zucchini are fruits. Since they aren’t sweet, we treat them as vegetables in the kitchen.
The point of zucchini bread isn’t to celebrate the flavor of zucchini. It’s usually made for one of two reasons: 1. to use up excess zucchini from your summer garden. 2. nostalgia. Someone in your life made zucchini bread and you liked it. So when summer rolls around, you want to make a loaf. Both of these are excellent reasons to make zucchini bread.
Traditional zucchini bread tastes mostly of cinnamon and is often studded with nuts or raisins. And, frankly, when I’m in the mood for a spiced quick bread, I usually make gluten-free pumpkin bread or gluten-free banana bread.
But chocolate zucchini bread? Well, that’s a different story. This is a bread I get excited to make. Chocolate zucchini bread is dense, moist, and, compared to other chocolate cakes, lower in fat. You can eat a slice without it feeling like an overindulgence.
The zucchini almost melts during baking and leaves behind a mild vegetable-sweetness that pairs really well with cocoa powder. And the texture, especially for gluten-free quick bread, is soft. There’s not a hint of gumminess in this bread.
Ingredients Explained
Here’s what you’ll need to make this recipe.
- Zucchini. Make sure your zucchini is fresh-not dried out. Select zucchini that’s about 12-inches long. If you have an overgrown zucchini, slice it in half. Scoop out the seeds, and then grate. There’s no need to remove the seeds from small zucchini.
- Gluten-Free Flour: To keep things easy, I used Bob’s Red Mill 1:1 Gluten-Free Baking Flour. It makes a bread with a very delicate crumb. If you use your own flour blend or a different brand, be sure it contains xanthan gum for structure. Do not substitute coconut or almond flour for the all-purpose gluten-free baking flour. It won’t work.
- Cocoa Powder. Use unsweetened regular cocoa powder-not Dutch-process for this recipe. It works with the baking soda to make the bread rise.
- Brown sugar. Adds sweetness and a light molasses flavor.
- Eggs. Give the bread structure. This recipe hasn’t been tested with an egg replacer.
- Oil. Adds richness.
How to Make Gluten-Free Chocolate Zucchini Bread
- Grate the zucchini. Use in-season zucchini. The bread needs the moisture it contains. To grate, use a box grater or food processor fitted with a grating disk.
- Mix together the dry ingredients in a large bowl. Whisk together the gluten-free flour with the cocoa powder and other dry ingredients. You don’t need a stand mixer for this recipe but you can use one.
- Make the batter. Add the eggs, oil, and zucchini. Stir until the zucchini is coated with batter. At first, the batter might look dry. This is normal.
- Give it a rest. Allow the batter to rest for two minutes. The zucchini gives off liquid during this time. Don’t skip the rest.
- Bake. Spoon batter into a greased pan and bake until set.
- Cool. Cool the bread, set on a wire rack, until cool to the touch.
Storage Tips
Store this bread covered on the counter for up to three days.
Gluten-Free chocolate zucchini bread freezes really well.
After baking, allow the loaf to cool completely. Slice and place parchment paper between the slices. Place the slices into a freezer bag and freeze up to three months.
Gluten-Free Zucchini Bread
Moist and rich, this gluten-free chocolate zucchini bread is an easy-to-make summer classic. Dairy-Free.
Ingredients
- 1 cup Bob's Red Mill 1:1 gluten-free baking flour (4 ¾ ounces ; 138 grams)
- ¾ cup dark brown sugar (5 ½ ounces; 155 grams)
- ⅓ cup unsweetened cocoa powder (1 ounce; 28 grams)
- 1 teaspoon baking soda
- ¼ teaspoon salt
- 2 cups grated zucchini, see note (9 ounces; 55 grams)
- 2 large eggs
- ⅓ cup vegetable oil (2 ⅓ ounces; 65 grams)
- 1 tablespoons chocolate chips, optional (⅓ ounce ;10 grams)
Instructions
-
Preheat oven to 350℉. Grease a 9×5-inch loaf pan with nonstick cooking spray.
-
Whisk together gluten-free flour, dark brown sugar, cocoa powder, baking soda, and salt. Break up any pieces of brown sugar with your fingers. Add grated zucchini, eggs, and oil. Stir until a batter forms. Allow batter to rest for two minutes. This allows the zucchini to release a little moisture. It’s an important step. You don’t want to skip it.
-
Stir the batter one more time to ensure no dry flour clings to the bottom of the bowl. Spread batter evenly into prepared pan. Sprinkle chocolate chips evenly over the top of the pan.
-
Bake until a cake tester inserted into the center of the loaf comes out with only a few crumbs clinging to it, about 45 minutes.
-
Place pan on wire rack. Allow bread to cool in the pan. Slide a metal spatula gently around the edges of the pan to loosen. Turn out bread. Slice with a serrated knife. Store zucchini bread, wrapped, on the counter for up to four days. To freeze: Slice bread and place parchment paper between the slices. Place the slices into a freezer bag and freeze up to three months.
Recipe Notes
Grated Zucchini
For small (under 12-inches) zucchini, there is no need to drain or blot. For large zucchini, over, blot to remove excess moisture.
Marilyn J. Taves says
The best gluten-free item I have baked. Very moist, chocolatey, not too oily. I added 10 more minutes of baking at five minute intervals for a total of 45 minutes.
RB says
I used a very large homegrown Zucchini from a friends garden (14 inch long by 3 1/2 inches wide). It was much juicier than a store bought one and released a TON of water in the bowl. I didn’t drain it, as it didn’t say to. Was I supposed to? I ended up baking it for an hour and 15 minutes to 1 hour and a half as it was still gooey in the center after 35 minutes. It’s still moist in the center but not gooey anymore. I didn’t have brown sugar so I used raw sugar and cut it to 1/2 cup instead of 3/4 cup. It tastes amazing! I’m just getting into gluten free baking and still intimidated. I would definitely make this again though!

Hi RB,
It sounds like the zucchini you used was pretty big! As I noted, you don’t want to use a zucchini larger than 12-inches. If you use a zucchini that big again, you can drain it. If it’s smaller, there’s really no need.
I hope this helps!
Heather Kaley says
This was fantastic. I’ve never made any kind of bread from scratch. I had a very large zucchini from my garden and I quadrupled this recipe since I had about 8 cups after I shredded it. I followed the recipe and I ended up making 6 smaller loaves out of it! Total baking time was 45 minutes exactly. Absolutely delicious, I will be adding this to my staple recipes!

Hi
I am making this for the first time for Thanksgiving. I have in-laws that are gluten free.
One question – I was wondering why there wasn’t any baking powder. Doesn’t that help it to rise?
Thanks
Denise
Elizabeth says
The baking soda works with the cocoa powder to make the bread rise. This one doesn’t need baking powder. Enjoy!
Ramona says
Best zucchini chocolate bread recipe gluten or not gluten free. We were fighting over the last piece. Thank you
Ruby says
I’ve been in love with your recipe! I added some vanilla extract and instant espresso and it had a nice sweet coffee flavor! Thanks for sharing. Will make again!
David says
Yum! Amazing! It was like a lovely fluffy chocolate cake. Will make again and again!
Tami says
With a larger zucchini for you scoop seeds out first then shred?
Elizabeth says
Yes! If you’re using an overgrown zucchini with large seeds, scoop the seeds and then shred.
Rik says
This recipe turned out great, very moist and not overly sweet.
