Chocolate Zucchini Bread Recipe
I love enjoying a slice of this chocolate zucchini bread at any hour of the day, but it’s really amazing in the morning with a cup of coffee. The rich chocolate flavor and moist, dense consistency pairs so well with a cup of joe!
If you’ve never had chocolate zucchini bread before, you might be hesitant, and I totally get it. It might seem odd that there are 2 cups of grated zucchini in this dessert recipe, but I promise you’ll never know it’s in there once it’s baked.
The grated zucchini adds a ton of moisture to this bread, which is what makes it so downright irresistible. I’m not quite sure who first looked at a zucchini and thought to toss it into a chocolate bread recipe, but I’m so glad they did!

How to make Chocolate Zucchini Bread with Chocolate Chips

- In a separate bowl, combine the vanilla extract, 2 eggs, melted butter, vegetable oil, and coffee granules.
- Combine the wet and dry ingredients.
- Fold in the grated zucchini.
- Fold in the dark chocolate chips.
- Pour mixture into the prepared loaf pan.
- Top the loaf with chocolate chips.
- Bake.
- Cool.
- Serve and enjoy!



While you can use any unsweetened cocoa powder you prefer, I like to use natural cocoa powder here because the baking soda helps to neutralize the acidity of natural cocoa powder, letting its rich flavor shine.
Other than the grated zucchini (which is the real secret ingredient for optimal moisture in this bread), the vegetable oil, butter and eggs all come together to create a seriously moist chocolate bread. If you want to add to that even more, stir in a tablespoon of melted coconut oil.
After the loaf comes out of the oven, I allow it to sit in the baking pan at room temperature for about 10 minutes or so. Then, I gently flip the loaf onto a wire rack and allow it to fully cool down for an hour. If you slice into the loaf while it’s still a bit warm, it will most likely crumble and fall apart. It needs that hour of cooling to get the perfect consistency.
In an airtight container at room temperature, this chocolate zucchini bread will stay fresh for up to 3 days. You can extend freshness by storing it in the refrigerator for up to 1 week. Enjoy it with coffee, ice cream, and so much more during that time!


Recipe Tips and Tricks
- You can use milk chocolate chips instead of dark if you’d prefer, but the chocolate flavor might not be as potent.
- The coffee can be omitted if desired, but I highly recommend leaving it in there! It creates a depth to the bread that’s truly divine.
- Be very careful not to bake this bread for too long! Once a toothpick inserted comes out clean, the bread is ready to cool. If baked too long, this moist bread will quickly dry out.

Notes
- Zucchini tends to lose its moisture over time. Fresh zucchini picked from a garden will have lots of extra liquid as you grate it. If you are using store-bought zucchini you may have to add 1-2 tablespoons of water to the batter to make it wet enough.
