Chocolate Zucchini Bread
This chocolate zucchini bread is what happens when your garden goes completely rogue in August and you find yourself drowning in zucchini. Desperation leads to genius, friends.
I started baking this one-bowl zucchini bread on a whim, and now my family requests it basically every single week. It’s fudgy, chocolatey, and honestly tastes more like dessert than anything remotely vegetable-adjacent.

Why You’ll Fall Hard for This Recipe
Can’t get enough of these flavors? You’re going to love what’s waiting in the lineup. Every single recipe is made to impress without the stress. Happy cooking, friend!
This isn’t your average zucchini bread. We’re talking deep chocolate flavor, a moist crumb that stays tender for days, and chocolate chips in every single bite.
The zucchini practically disappears into the batter. Nobody will guess there’s a vegetable hiding in there — not even the pickiest eaters at your table.
It comes together in one bowl, which means less cleanup. That alone is worth making it twice this week.
Ingredients You’ll Need
Everything here is straightforward pantry stuff. Dutch process cocoa gives you that extra-dark, rich chocolate flavor, but regular unsweetened cocoa works just fine too.
| Category | Ingredient | Amount |
|---|---|---|
| Dry Ingredients | All-purpose flour | 1 cup |
| Dutch process or unsweetened cocoa powder | 1/2 cup | |
| Baking soda | 1 teaspoon | |
| Sea salt | 1/2 teaspoon | |
| Wet Ingredients | Large eggs, room temperature | 2 |
| Unsalted butter, melted and cooled | 1/4 cup | |
| Canola, vegetable, or melted coconut oil | 1/4 cup | |
| Packed light brown sugar | 3/4 cup | |
| Pure vanilla extract | 1 teaspoon | |
| The Star | Packed shredded zucchini | 1 1/2 cups |
| Mix-Ins | Semisweet chocolate chips, divided | 1 cup |
A quick note on the oil: using both butter and oil gives you the best of both worlds — rich flavor from the butter and a moist, tender texture from the oil.
How to Make Chocolate Zucchini Bread Step by Step
This is the easiest bake you’ll make this season. Promise. It’s a true one-bowl zucchini bread situation, so grab your biggest mixing bowl and let’s go.
Step 1: Get Your Oven and Pan Ready
Preheat your oven to 350 degrees F. Grease a 9-by-5-inch loaf pan generously with nonstick cooking spray. Set it aside while you mix things up.
Don’t skip the pan prep — this batter is thick and sticky, and you’ll want the bread to slide right out after baking.
Step 2: Whisk Your Dry Ingredients
In a medium bowl, whisk together the flour, cocoa powder, baking soda, and sea salt. Give it a good stir until everything is combined and there are no cocoa clumps hiding at the bottom.
Set that bowl aside. We’ll come back to it in just a minute.
Step 3: Mix Your Wet Ingredients
In a large bowl, combine the eggs, melted butter, oil, vanilla extract, and brown sugar. Stir it all together until smooth and glossy.
Don’t stress if you see a few tiny brown sugar clumps — that’s completely normal and they’ll bake out just fine.
Step 4: Combine Wet and Dry
Stir the dry ingredients into the wet ingredients. Here’s the golden rule: don’t overmix. Stir just until everything comes together and you can’t see dry flour streaks anymore.
Overmixing makes the bread dense and tough. We want fudgy and tender, so less is more here.
Step 5: Fold in Zucchini and Chocolate Chips
Stir the shredded zucchini into the batter until just combined. Then fold in 3/4 cup of the chocolate chips. Save the last 1/4 cup for the top — this is the secret to that gorgeous, chip-studded crust.
The batter will look very thick. That’s exactly what you want. Trust the process.
Step 6: Bake It Low and Slow
Pour the batter into your prepared loaf pan. Sprinkle the remaining 1/4 cup of chocolate chips across the top of the batter.
Bake for 50 to 60 minutes, until a toothpick inserted in the center comes out mostly clean. You might see a little melted chocolate on the toothpick from the chips — that’s fine. What you don’t want is gooey, wet batter.
Step 7: Cool Before Slicing
Remove the pan from the oven and let the bread cool on a wire rack for 15 minutes. Then run a knife around the edges, carefully lift it out, and let it finish cooling on the rack.
I know it smells incredible and waiting feels impossible. But cutting into it too early makes it fall apart. Give it at least 20 more minutes. You’ve got this.
Expert Tips for the Best Results
Shredding Your Zucchini
Use the large holes on a box grater. You don’t need to peel the zucchini first — the skin is tender and totally undetectable in the finished bread.
After shredding, pack the zucchini into your measuring cup firmly. You want a full 1 1/2 cups for maximum moisture.
Don’t Squeeze the Zucchini
Unlike some recipes, you do NOT need to wring out the moisture from the zucchini here. That natural moisture is what keeps the bread so irresistibly soft. Leave it as is.
Room Temperature Eggs Matter
Cold eggs can cause the melted butter to seize up and clump. Pull your eggs out of the fridge about 30 minutes before you start baking. It makes the batter come together so much more smoothly.
Using Coconut Oil
If you’re using coconut oil instead of vegetable or canola oil, make sure it’s fully melted and slightly cooled before adding it to the batter. Hot coconut oil can scramble your eggs, and that is not the vibe we’re going for.
Fun Variations to Try
Make Mini Loaves
This batter works beautifully as a mini loaf zucchini bread recipe. Divide the batter evenly among a greased mini loaf pan and bake at 350 degrees F for 25 to 35 minutes, checking with a toothpick around the 25-minute mark.
Mini loaves also make adorable gifts. Just wrap them in parchment and tie with a ribbon. People will absolutely love you for it.
Go Full Chocolate Chip
Want to make this into a true chocolate chip zucchini bread with mini loaves? Use mini chocolate chips instead of regular ones. They distribute more evenly throughout the batter and give you chocolate in every single bite.
Add Nuts
Fold in 1/2 cup of chopped walnuts or pecans along with the chocolate chips for a little crunch. It plays so nicely against the fudgy, soft texture of the bread.
Make It Dairy-Free
Swap the butter for an equal amount of additional oil. Use dairy-free chocolate chips. The result is just as moist and delicious — no one will know the difference.
Troubleshooting Common Issues
Bread Is Gummy in the Center
This usually means it needs more time in the oven. Ovens vary a lot. If your toothpick comes out with wet batter (not just melted chocolate), cover the top loosely with foil and bake for another 10 minutes.
Bread Sank in the Middle
A sunken loaf is almost always caused by underbaking or opening the oven door too early. Resist the urge to peek until at least the 45-minute mark. Let that heat do its job.
Bread Turned Out Too Dense
Overmixing the batter is the most common culprit. Stir only until the dry ingredients are just incorporated. A few small streaks of flour are okay — they’ll hydrate during baking.
Storage and Make-Ahead Guide
This chocolate zucchini bread keeps beautifully and actually gets even more moist on day two. Here’s how to store it properly.
| Storage Method | How To | Duration |
|---|---|---|
| Counter | Wrap tightly in plastic wrap | Up to 4 days |
| Freezer (whole loaf) | Wrap in plastic wrap, then aluminum foil | Up to 1 month |
| Freezer (slices) | Wrap individual slices, store in a zip-top bag | Up to 1 month |
To freeze, make sure the bread is completely cool before wrapping. Defrost at room temperature before slicing. Freezing individual slices means you can grab one anytime without defrosting the whole loaf.
Reheating Tips
A slice is wonderful at room temperature, but a quick 15 to 20 seconds in the microwave makes those chocolate chips all melty again. It feels like you just pulled it out of the oven.
No-Waste Kitchen Ideas
If your bread is starting to dry out by day four, cube it up and use it to make a chocolate bread pudding. Or crumble it over vanilla ice cream for the best impromptu dessert of your life.

Frequently Asked Questions
Do I need to peel the zucchini before shredding?
Nope! The skin is very tender and completely disappears into the batter once baked. Just give the zucchini a rinse, trim the ends, and shred it right on your box grater. Easy as that.
Can I reduce the sugar in this chocolate zucchini bread?
You can reduce it slightly — try cutting it down to 1/2 cup instead of 3/4 cup. Just know that the bread will be less moist and the sweetness will be more subtle. The chocolate chips add sweetness too, so it still balances out nicely.
Can I use a different pan size?
Yes! This batter works great in an 8-by-4-inch loaf pan — just check it a few minutes earlier since the loaf will be taller. You can also use it as a mini loaf zucchini bread recipe by dividing the batter into a greased mini loaf pan and reducing the bake time to about 25 to 35 minutes.
Why is my bread not fully cooked even after 60 minutes?
Zucchini holds a lot of moisture, and every oven runs a little differently. If the toothpick comes out with wet batter at 60 minutes, tent the top of the loaf with foil and bake in 5-minute increments until it tests clean. The foil prevents the top from over-browning while the center finishes cooking.
Can I make this one bowl zucchini bread ahead of time?
Absolutely, and it’s actually better on day two. The flavors deepen overnight and the crumb gets even more moist. Bake it the day before you need it, wrap it tightly, and store it on the counter. Slice it fresh the next morning and enjoy.
