Directions
-
I preheat my oven to 350°F and grease a standard loaf pan.
-
In a large bowl, I whisk together the flour, cocoa powder, baking soda, and salt.
-
In another bowl, I beat the sugar, eggs, oil, and vanilla until smooth.
-
I stir in the grated zucchini, making sure it’s evenly mixed.
-
I add the dry ingredients to the wet mixture, stirring just until combined.
-
I fold in the chocolate chips, reserving a handful for topping.
-
I pour the batter into the prepared loaf pan and sprinkle the reserved chips on top.
-
I bake for 50–60 minutes, or until a toothpick inserted in the center comes out mostly clean (a few moist crumbs are fine).
-
I let it cool in the pan for 10 minutes before transferring to a wire rack.
Servings And Timing
This recipe makes about 8–10 slices. It takes around 15 minutes to prepare, plus 50–60 minutes to bake, and about 10 minutes to cool before slicing.
Variations
I sometimes swap half the semi-sweet chips for white chocolate or peanut butter chips for extra flavor. For a richer loaf, I add a teaspoon of espresso powder to intensify the chocolate taste. If I’m in the mood for more texture, I toss in a handful of chopped walnuts.
Storage/Reheating
I keep the bread in an airtight container at room temperature for up to 3 days. For longer storage, I wrap it well and freeze it for up to 3 months. To reheat, I microwave slices for 15–20 seconds or warm them in a low oven.
FAQs
Can I Make This Bread Gluten-Free?
Yes, I replace the all-purpose flour with a 1:1 gluten-free baking blend and it turns out great.
Should I Peel The Zucchini First?
No, I leave the skin on because it softens during baking and adds color.
Can I Use Dark Chocolate Chips Instead Of Semi-Sweet?
Absolutely, they make the loaf even richer.
Why Is My Bread Sinking In The Middle?
This can happen if the batter is overmixed or if the loaf is underbaked. I make sure to mix gently and test for doneness.
Can I Make Muffins From This Batter?
Yes, I bake muffins at the same temperature for about 18–22 minutes.
Conclusion
I love how this double chocolate zucchini bread transforms simple ingredients into a moist, fudgy loaf with irresistible chocolate flavor. It’s the perfect balance of indulgence and comfort, making it a recipe I reach for whenever I have extra zucchini and a chocolate craving.

Description
Rich, moist zucchini bread loaded with cocoa and chocolate chips for a decadent, bakery-worthy treat.
Ingredients
1 cup all-purpose flour
½ cup Dutch-process cocoa powder (or unsweetened cocoa if unavailable)
1 teaspoon baking soda
½ teaspoon sea salt
2 large eggs (room temperature)
¼ cup unsalted butter, melted and slightly cooled
¼ cup canola oil (or melted coconut oil)
¾ cup packed light brown sugar
1 teaspoon pure vanilla extract
1½ cups packed shredded zucchini
1 cup semisweet chocolate chips, divided (¾ cup mixed in, ¼ cup for topping)
Instructions
Preheat oven to 350 °F (175 °C). Grease a 9×5‑inch loaf pan.
Whisk together flour, cocoa, baking soda, and salt in a medium bowl.
In a large bowl, mix eggs, melted butter, oil, brown sugar, and vanilla until smooth.
Gently stir dry ingredients into wet until just combined, then fold in zucchini and ¾ cup of chocolate chips.
Pour batter into the prepared pan. Top with the remaining ¼ cup of chocolate chips.
Bake 50–60 minutes, or until a toothpick inserted into the center comes out mostly clean.
Cool in pan for 10–15 minutes, then transfer to a wire rack to cool completely before slicing.
Notes
No need to squeeze zucchini—excess moisture is absorbed by cocoa powder.
Dutch-process cocoa yields smoother, richer flavor, but unsweetened works as a substitute.
Freezes well for up to 1 month.
