When it comes to baking, quick breads are BOSS. They’re easy, delicious, and basically fool-proof, and they’re a great base for SO many different flavor combos!

This Chocolate Zucchini Bread is one of our favorite combinations ever… not just because of the chocolate, but because of the zucchini. Fresh zucchini adds amazing moisture, flavor, and texture to baked goods… and when you combine it with chocolate, it’s even better!

Worried about tasting zucchini in your bread? Have no fear… you won’t! It’s like a magical secret ingredient that can’t quite be detected. It just has a way of making all your favorites taste even better! Once you know, you know.

Ingredients in Chocolate Zucchini Bread

Eggs – This recipe calls for 3 large eggs. To substitute egg whites only, use 2 egg whites for each egg.

Oil – In addition to the zucchini, oil helps to make this bread extra moist and delicious. I used canola oil, which is always my go-to for baking.

Sugar – I used granulated sugar in this recipe. You can substitute brown sugar or use a combination of the two.

Vanilla – You can never go wrong with vanilla in a quick bread. I used pure vanilla extract. You can use imitation or pure… either will work fine.

Milk – For added moisture, you’ll need a little bit of milk. I used 2%, but any percentage will work. You can even use half & half if that’s what you have on hand.

Flour – I used regular all purpose flour. Any type will work, but be sure to follow the substitution guidelines on the package.

Salt – A touch of salt brings out all the other flavors. My advice? Don’t skip it!

Baking soda – Baking soda is a necessary leavening agent in this recipe. To substitute baking powder, you’ll need to use 4x as much.

Cinnamon – I often add a bit of cinnamon to my quick breads. This is an optional ingredient, but it adds a delicious layer of flavor to the bread.

Cocoa powder – The chocolate flavor in this bread comes from unsweetened cocoa powder. For extra chocolate flavor, feel free to add chocolate chips!

Shredded zucchini – Finally… the star of the show… shredded zucchini! You can use peeled or unpeeled zucchini, and the shred size is up to you. (I used finely shredded based on personal preference.)

Chocolate chips – Chocolate chips are an optional, yet delicious addition to this bread. Add up to 1 cup regular or mini chocolate chips for extra chocolate flavor.

    1. Yummy! This chocolate zucchini bread looks amazing and so delicious! This is going to be gone so quick. I can’t wait to make this!

    2. I made this today. I topped one loaf with sliced almonds. Very good and moist. I will make this chocolate zucchini bread again!

    3. This is my second “go-round” with this recipe. The first time, I followed it to a “T”. Delicious! This time, I’m using coconut oil in place of 2/3 of the vegetable oil, and also adding shredded coconut. My house smells heavenly

    4. 5 stars
