Chocolate zucchini bread is my go-to bake for those days when I want something indulgent yet secretly packed with goodness. The grated zucchini melts right into the batter, leaving you with a tender moist loaf bursting with chocolate chips and deep cocoa flavor. Whether you are sneaking in extra veggies for your kids or looking for a crowd-pleaser at brunch, this loaf always disappears fast from my kitchen counter.
I first made this on a whim when my garden was overflowing with zucchini one summer. It instantly became one of my most requested recipes and even picky eaters come back for seconds.
Ingredients
- All purpose flour: gives the base a soft yet structured crumb. Go for unbleached for best flavor.
- Unsweetened cocoa powder: packs in real chocolate depth. Dutch process or natural both work well.
- Baking soda and baking powder: lift the bread for the right rise. Check freshness before using.
- Salt: balances both the sweet and chocolate tones.
- Light brown sugar: adds moisture and subtle caramel notes. Make sure it feels soft and lump free.
- White sugar: brings pure sweetness and keeps the texture light.
- Large eggs: bind everything together and add a touch of richness. Let them warm to room temperature.
- Unsalted butter: lends richness. Soften it for effortless mixing.
- Canola oil: gives a bit of extra moisture to create a truly tender loaf.
- Vanilla extract: enhances the aroma and flavor. Opt for pure extract over imitation if possible.
- Shredded zucchini: is the secret to moisture. Choose small to medium zucchini with smooth skin for the most tender shreds.
- Semi sweet chocolate chips: ensure you get melty pockets of chocolate in every slice. Use quality chips for best results.
Instructions
- Preheat Oven:
- Set your oven to three hundred fifty degrees Fahrenheit. This ensures even baking from the start.
- Mix Dry Ingredients:
- Combine your all purpose flour, unsweetened cocoa, baking soda, baking powder, salt, light brown sugar, and white sugar in a medium bowl. Stir thoroughly so the leavening and sugars are evenly distributed throughout the flour.
- Beat Wet Ingredients:
- In a separate large bowl, add eggs, softened butter, canola oil, and vanilla extract. Beat on medium speed for about one minute until the mixture is smooth and light yellow. This step is key for even crumb texture.
- Add Zucchini:
- Take your packed shredded zucchini and add it to the wet mixture. Use the mixer on low and blend for just ten seconds. This helps distribute the moisture from the zucchini into your batter without making it dense.
- Combine Mixtures:
- Gradually add your dry mix into the wet, stirring gently after each addition. Stop mixing as soon as no dry streaks are left. Overmixing here will make your loaf tough.
- Add Chocolate Chips:
- Fold in the chocolate chips with a spatula. Set aside a small handful to sprinkle on top before baking. This ensures every slice has chocolate both inside and out.
- Prepare Pan:
- Lightly grease an eight by four inch loaf pan. Pour in the batter and smooth the top. Sprinkle that reserved handful of chips over the surface for a bakery-style finish.
- Bake:
- Place your filled pan in the preheated oven. Bake for fifty minutes. When a toothpick inserted into the center comes out mostly clean or with a few moist crumbs, it is ready.
- Rest:
- Let the bread rest in its pan for five minutes after baking. This helps it hold together as you remove it.
- Cool:
- Lift the loaf out and transfer to a wire rack. Let cool completely before slicing so you get neat clean slices that hold their shape.

The semi sweet chocolate chips are my favorite part because they create gooey pockets that remind me of my childhood after school snacks. My kids love helping sprinkle extra chips over the batter and we always sneak the first slice while it is still barely warm.
Storage Tips
Keep your chocolate zucchini bread tightly wrapped at room temperature for up to three days. For longer storage, refrigerate up to one week. If you want to freeze, slice the cooled bread and wrap each piece in cling film and foil for up to three months. Grab slices as needed and thaw at room temperature or pop in the toaster oven.
Ingredient Substitutions
You can swap in white whole wheat flour for half of the all purpose flour for a nuttier, heartier bite. Greek yogurt can replace half the butter for a lighter version though the loaf will be less rich. If you need to go dairy free, use melted coconut oil and a plant based butter alternative. Dark chocolate chips work just as deliciously here.
Serving Suggestions
Serve a thick slice slightly warmed with a smear of salted butter for breakfast. For dessert, try it with a scoop of vanilla ice cream or a dusting of powdered sugar. Pack it up for picnics or lunchboxes and watch it disappear.
Cultural Context
Zucchini bread has roots in American home gardens dating back to the mid-twentieth century when resourceful bakers found ways to use the summer bounty of zucchini. Adding chocolate elevates a humble loaf, making this version a beloved classic at bake sales and family gatherings.
Seasonal Adaptations
Use summer’s fresh zucchini for maximum tenderness Add a dash of cinnamon in fall for cozy warmth In winter swirl in a spoonful of orange zest for a richer aroma
Success Stories
Readers tell me this bread is a hit at kids’ parties and potlucks and even those who claim to hate zucchini never guess what is inside. One friend made it for teachers appreciation week and came home with an empty plate and a stack of recipe requests.
Freezer Meal Conversion
This bread freezes incredibly well. Cool the loaf completely slice and wrap individually for easy grab and go snacks. I often freeze half so we do not eat the whole loaf in one weekend.

This chocolate zucchini bread is guaranteed to become a household favorite. Enjoy every rich slice and do not be surprised when everyone asks for seconds.
