This chocolate zucchini bread is delectable and moist with plenty of fresh zucchini, Dutch-process cocoa, and semi-sweet chocolate chips. It is truly a chocolate lover’s delight.

If your family is anything like mine, chocolate is an indulgence you simply can not live without, and the darker and richer it is, the better. If you like this chocolate recipe, try chocolate pudding, earthquake cake, and chocolate cream pie.
Ingredient Notes and Substitutions
See the complete list of ingredients below on the recipe card.
- Cocoa powder: Use good-quality unsweetened Dutch-process cocoa powder, like Ghirardelli. It will give your chocolate bread a richer flavor.
- Zucchini: You can use fresh or frozen. If using frozen shredded zucchini, drain it in a colander in the sink or squeeze it in a tea towel before starting the recipe to remove any excess moisture.
- Butter: Unsalted or salted. If using salted butter, reduce the added salt to ¼ teaspoon.
- Oil: Use a neutral oil like vegetable, canola, or safflower.
- Vanilla extract: Always use the pure stuff, please.
- Chocolate chips: Use semisweet or dark chocolate. Quality matters; my two favorite brands are Ghirardelli and Guittard.
How To Make Chocolate Zucchini Bread
This is a summary version; for the complete list of ingredients and instructions, please refer to the recipe card below.
- Whisk the flour, cocoa powder, baking soda, baking powder, and salt.
- Mix the shredded zucchini, granulated sugar, brown sugar, butter, vegetable oil, eggs, and vanilla extract.
- Add the dry ingredients to the wet ingredients and stir just until combined. Fold in the chocolate chips.
- Bake until a toothpick inserted in the center comes out clean or with a few moist crumbs.


Preparation Tips
- Use the correct baking pan. I use a nonstick 9×5-inch steel loaf pan. Avoid glass pans as they can lead to overcooked, dry loaves. Avoid nonstick pans that are too dark. I find that the crust gets too dark and looks burnt.
- Grease and flour your loaf pan. I use Pam baking spray with flour.
- For the best results, mix the batter just until combined. Overmixing can make the loaf tough and gummy.
- Nut lovers try adding chopped pecans or chopped walnuts.
- Top the loaf with a handful of semisweet chocolate chips before baking for an over-the-top presentation. Be very careful removing the loaf from the pan, the chocolate chips will be very soft.
