If chocolate cake had a healthier cousin, it would be this Double Chocolate Zucchini Bread!
Chocolatey from both cocoa powder and chocolate chips, this quick bread feels like dessert, but it’s also a great breakfast treat or midday snack.
If you’re nervous about a veggie with your chocolate, fear not, zucchini is tasteless and it melds right into the loaf.
My zucchini-fearing kids saw me grating zucchini and asked what it was for. I told them it’s for chocolate zucchini bread and they were SKEPTICAL!! Guess what?
They loved it! Now I can remind them that they do like zucchini ;)

How to serve Chocolate Zucchini Bread
My favorite way to eat this bread is warm. If I’m eating it the next day, I like to pop it in the microwave to get the chocolate chips soft again.
Chocolate Zucchini Bread is great served:
- For breakfast with fresh fruit
- Mother’s Day brunch
- Afternoon snack
- Sweet, healthyish treat for lunchboxes
- Dessert
💡Tips & Tricks
- Zucchini: Zucchini is made up of approximately 95% water, so it adds lots of moisture to the bread. I’ve tried both the large and smaller holes on the box grater. Either work.
- Chocolate chips: Feel free to use whatever kind of chocolate chips you like. We like the semi-sweet best for this recipe.
- Cocoa powder: This recipe was developed using regular cocoa powder. It has not been tested with “special dark” or Dutch-process varieties.
If you grow zucchini in the summer, this bread and my Baked Turkey, Zucchini & Feta Meatballs are great ways to use it up.

Double Chocolate Zucchini Bread
Equipment
- Mixing bowl
Ingredients
- 1 1/2 cups all-purpose flour see notes below for proper measuring
- 1 cup light brown sugar
- 1/2 cup cocoa powder not Dutch-process
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon sea salt
- 2 large eggs whisked
- 1/2 cup vegetable oil
- 1/4 cup milk regular and oat milk worked great
- 1 teaspoon vanilla extract
- 13 ounces zucchini unpeeled
- 1 cup semi-sweet chocolate chips plus more for the top
Instructions
- Preheat oven to 350℉ and line your loaf pan with parchment paper.
- Add the flour, brown sugar, cocoa powder, baking powder, baking soda, and salt to a large mixing bowl. Stir and make sure everything is combined well.
- Add the whisked eggs, oil, milk, and vanilla to the bowl with dry ingredients. Stir until well combined and there are no dry spots.
- Grate the zucchini on a box grater, then fold it into the batter, followed by the chocolate chips.
- Pour the batter into the loaf pan. I like to drop some extra chocolate chips on the top of the batter. It looks nice and more chocolate never hurt! Bake for 55-65 minutes, or until done. Check it at the 55-minute mark with a toothpick. Because of the chocolate chips, the toothpick may not come out clean. We want to see a slight crumb, not raw batter.
- Let the loaf cool in the pan for an hour before slicing. Enjoy!

Notes
- I have made this with regular milk and oat milk and both work great.
- Make sure to use the “spoon & level” method for measuring flour – use a spoon to fill a measuring cup and level it off with a knife. Don’t scoop flour with the measuring cup, as that compacts it.
- 13 ounces of zucchini, grated, will produce approximately 1 1/2 slightly packed cups of zucchini.
- This recipe was tested with a glass loaf pan.
- Store cooled bread covered at room temperature for 3-4 days, or in the fridge for up to a week. Can be frozen if tightly wrapped in plastic wrap or parchment paper and foil. For the best quality, use within 3 months.
Tastes like there isn’t even zucchini!
