It doesn’t seem to matter where I live, whether I have my own garden or not. Every year, there seems to be an overabundance of zucchini that seems to find its way into my kitchen sooner or later.
And as someone who doesn’t care for zucchini very much, and lives with a family who also isn’t very fond of it. I have, needless to say, had my work cut out for me in the kitchen when it comes to figuring out easy and delicious ways to use up our zucchini supply.

This quick bread recipe, though, actually came about due to it being a repeated request from my baby sister. She had a chocolate chip zucchini bread once, and has been begging me to create a recipe for it ever since.
And while I am no stranger to making quick breads or making desserts with zucchini. I’ve made everything from chocolate zucchini cake to zucchini pancakes, and even shredded zucchini frosting.

But for some reason, this recipe idea got pushed to the back burner, and it took me a good two years to get back to it. Thankfully, this chocolate bread seems to have been worth the wait.
This easy and delicious double chocolate zucchini bread is great for any time of the day. It’s perfect for bringing to events or gifting to friends.
It has been given the stamp of approval from my baby sister as well as the rest of my family. Plus, it is a great and easy way to use up your abundance of zucchini!

How To Make Double Chocolate Zucchini Bread
Ingredients
- unsalted butter, melted + more for greasing the pan. I like to use butter to grease my loaf pan, but you can also use a neutral oil. Vegetable oil, avocado oil, and grape seed oil will all work well.
- Unsweetened cocoa powder, + more for dusting the pan. I usually use regular cocoa powder, but you can also use Dutch process cocoa powder, or even black cocoa powder!
- all-purpose flour
- baking soda
- sea salt
- white sugar
- egg
- egg yolk
- vanilla extract
- grated zucchini, peeled or unpeeled. I usually peel mine, be either way will work. You’ll need about 1 large zucchini or 2-3 small ones
- Chocolate chunks. You can also use dark or semisweet chocolate chips

Directions
Preheat the oven to 350 degrees F. Butter/grease a 9×5 loaf pan, dust with cocoa powder, tapping out an excess, and set aside until ready to use.
In a large bowl, whisk together the dry ingredients(the flour, cocoa powder, baking soda, and salt).
In a separate large mixing bowl, combine all the wet ingredients, except the grated zucchini (the sugar, melted butter, egg, egg yolk, and vanilla). Add the zucchini and fold with a wooden spoon or rubber spatula until just incorporated.
Add the flour mixture to the zucchini mixture 1/3 at a time, folding until combined between each addition.
Finally, add the chocolate chunks(or chocolate chips) and fold to mix.
Spoon finished batter into your prepared loaf pan, and place it in the oven.
Bake for 50 minutes, or until a toothpick inserted into the center of the loaf comes out clean.
Allow the bread to cool in the pan for at least 10 minutes before turning it out onto a wire rack to finish cooling. Cool to room temperature, then slice and serve.
Enjoy!

Recipe Notes
Any leftover zucchini bread can be stored in an airtight container or wrapped tightly in plastic wrap and kept at room temperature for up to 3 days!
For easier clean up, you can line your loaf pan with parchment paper instead of greasing it.
This recipe is the perfect recipe for zucchini season, and I love all the fun and easy ways you can change up this bread to fit whatever you are craving! You can add a teaspoon of ground cinnamon to create a warmer flavor. Or add a teaspoon of instant coffee or espresso powder to make a delicious double chocolate mocha bread! You can also top your bread with flaky salt or extra chocolate!
This recipe can also be made with yellow zucchini/summer squash!
And feel free to play around with different flours and sugars to make this recipe a little healthier! Wheat flour, GF flour, or even fresh milled flour would all work great! Brown sugar, coconut sugar, and even maple syrup can all be used to sweeten this easy bread.
