Soft, moist and delicious chocolate bread with zucchini that you can't even taste! This easy chocolate zucchini oat bread is a great dessert or snack made with simple ingredients. [Dairy-free and gluten-free adaptable]
My simple chocolate zucchini oat bread recipe is made from rolled oats, cocoa powder, chocolate chips, grated zucchini, egg, vanilla, sugar, salt, baking powder and baking soda.
The rolled oats and zucchini adds fiber to this sweet treat making it slightly healthier. You can barely taste the vegetables as zucchini is very neutral in taste.
It's great for picky-eaters, like kids, who want to add more fiber to their diet without it feeling like a chore.
The recipe is very easy and you can even use a food processor to help you quickly grate the zucchini with a grating tool.
This can also be dairy-free and gluten-free with substitutions that I share below.
Ingredients & Substitutes
Please scroll down to below recipe card for exact measurements.
- Melted Coconut Oil: or substitute with a neutral tasting oil like vegetable oil, avocado oil, canola oil. Avoid using olive oil as a substitute as it's too overpowering in taste.
- White granulated sugar: or substitute with cane sugar.
- Large Eggs
- Vanilla Extract
- Rolled Oats: or substitute with instant oats, steel cut oats or 1 cup of ground oat flour or all-purpose flour. If you're gluten-free, make sure you're using certified gluten-free rolled oats.
- Cocoa powder
- Salt
- Baking Powder
- Baking Soda
- Zucchini: both the green or yellow kind will work.
- Regular-Sized Chocolate Chips: milk or dark chocolate chips both work. If you're dairy-free, substitute with vegan chocolate chips. You can find these type of chocolate chips at select grocery stores or health food stores or online.
Expert Tips
- Use fresh zucchini and avoid using any that are browning or dented.
- Do not over mix the initial batter or it'll become too dense in texture.
- Be gentle and use a spatula when mixing in the grated zucchini to avoid over mixing the batter.
- Do not over bake and use the toothpick test as instructed! The toothpick should come out 90% clean with a bit of batter on it so the bread can remain moist.
Instructions
Below are step-by-step instructions on how to make chocolate zucchini oat bread:
- Preheat the oven to 350 degrees F. Grease a loaf pan with coconut oil using a clean paper towel or line the loaf pan with enough parchment paper. Set aside.
- Remove the ends of a unpeeled zucchini. Grate the zucchinis on a box grater using the largest setting and set aside. If you have a food processor with a grating blade, you can also use that.
- Next in a blender, blend rolled oats on high until you have a fine flour and set aside. If you're using oat flour, skip this step and substitute with 1 cup of ground oat flour.
- In a large mixing bowl, whisk together melted coconut oil and sugar until combined. Then add eggs and vanilla extract and mix until combined. Set aside.
- In another large bowl, whisk together oat flour, cocoa powder, salt, baking powder, baking soda until combined. Add this to your wet batter and mix just until combined but do not over mix.
- Next mix in grated zucchini and half of the chocolate chips with a spatula. The mixture will be very thick, which is normal. Pour bread batter into your pan and smooth out the top with a spatula.
- Then evenly sprinkle remaining chocolate chips on top of the batter.
- Bake for 55-60 minutes until an inserted toothpick comes out 90% clean. You don't want the toothpick to come out completely clean or the bread will come out too dry and not moist.
- Place the loaf pan on a wire rack and let the bread sit in the pan for 10 minutes to cool down.
- Then run a knife around the edges of the loaf. Remove from the pan and transfer bread to a wire rack to cool down.
- Lastly slice and serve to enjoy warm or at room temperature.
Storage
- Leftovers will last up to 4 days stored in an airtight container wrapped in plastic wrap at room temperature or up to 7 days in the fridge. To reheat, microwave each slice for 20-40 seconds.
- Freezer-friendly? Chocolate zucchini bread will last up to 6 months in the freezer. To freeze: let the bread cool down completely and slice into equal pieces. Then wrap each slice in plastic wrap and store into a freezer-safe bag. To reheat each slice: microwave for 1-2 minutes until warm.

- brownies or my protein chocolate chip blondies

Thanks for sharing this recipe, Christie, I'm excited to try it! I have oat flour (already in flour form), and wondered if you knew what the conversion might be in your recipe? So, how many cups of oat flour emerges from 1 and 2/3 cups of rolled oats...?
christieathome
You're welcome Seema! It will equate to 1 cup of oat flour ๐ Hope this helps!
Sue
Made this just like the recipe, except in an individual brownie pan. It only took 18 minutes to cook and they were sooo good. This recipe is a keeper!

Oh my goodness! This is definitely my new favourite recipe. Only change I made was instead of sugar I used honey. It is so moist, and full of flavour!

Heidi | The Frugal Girls
That was such a great idea to make your own homemade oat flour... and those dark chocolate chips are simply too good to resist!
Eileen
This was delicious. I will definitely make it again. But 70 minutes was way too long for mine. It was done in about 40 minutes.

Thanks so much for letting me know! Glad you enjoyed the recipe.

This lovely chocolatey bread reminds me of a zucchini bread that I grew up eating. My Mom always made it, and it was the only time I didn't complain about eating zucchini! You can't even taste it, plus it adds so much moisture. Looks amazing, Christie!
Katerina
I love that you've managed to squeeze two cups of zucchini into this lovely chocolatey bread, Christie! As you know, we have so much zucchini in summer, that I am sure this recipe will definitely come in handy. I love the softness and fluffy texture that zucchini gives to all baked goods and this looks absolutely perfect!
Alex
This looks so delicious, Christie! I love the addition of the zucchini - very clever! And can never resist chocolate ๐
