Ingredients You’ll Need
This Chocolate Zucchini Cake comes together with easy-to-find ingredients that work together like magic: the cocoa brings bold flavor, while zucchini whispers away in the background, adding moisture and structure without stealing the spotlight. Each addition truly matters for that dream slice!
- All-purpose flour (or spelt/gluten-free blend): Provides the backbone for structure, so your cake holds together beautifully with a tender crumb.
- Unsweetened cocoa powder: Gives the cake its deep chocolate flavor; choose a high quality cocoa for the richest taste.
- Baking soda: Helps the cake rise, keeping it light rather than heavy or dense.
- Salt: Balances out the sweetness and intensifies the chocolatey notes.
- Granulated sugar (or coconut sugar/erythritol): Sweetens the cake, and your chosen type can tweak the flavor or make it lower in sugar.
- Water: Hydrates the batter and helps the flour absorb all those cocoa flavors.
- Melted coconut oil (or vegetable oil/softened almond butter): Ensures the cake stays moist—even after a couple of days!
- Pure vanilla extract: Brings out the warmth and complexity of all the other flavors.
- Shredded fresh zucchini, blotted: This is our secret weapon—delivers incredible moisture and improves texture without ever tasting like veggies.
- Mini chocolate chips (optional): For those who love extra bursts of chocolate in every bite, these little pockets are welcome additions.
How to Make Chocolate Zucchini Cake
Step 1: Prep Your Pan and Oven
First things first, set your oven to 350°F (175°C), and get your 9×13 inch baking pan ready by greasing it well or lining it with parchment paper. This ensures your Chocolate Zucchini Cake won’t stick, so slicing and serving are as easy as can be.
Step 2: Combine Your Dry Ingredients
In a large mixing bowl, whisk together your flour, unsweetened cocoa powder, baking soda, salt, sugar, and (if you’re using them) those irresistible mini chocolate chips. Mixing all the dry ingredients evenly now leads to a better rise and even distribution of flavors in every bite.
Step 3: Add Wet Ingredients and Zucchini
Now, add your water, melted oil (or almond butter), vanilla extract, and the all-important blotted shredded zucchini straight into the bowl. Give it a gentle stir—just until everything comes together and there are no big flour streaks. Resist the urge to overmix; that’s the best way to keep your Chocolate Zucchini Cake fluffy!
Step 4: Bake to Perfection
Pour your batter evenly into the prepared pan, smoothing the top just a bit. Transfer to the oven and let it bake for about 30 minutes. You’ll know it’s done when a toothpick poked in the center comes out almost clean (a tiny crumb or two is perfect).
Step 5: Cool and Finish
Let your cake cool completely in the pan so it sets up perfectly and doesn’t fall apart. For absolutely peak flavor and fudginess, cover and refrigerate your Chocolate Zucchini Cake overnight before slicing and serving—it’s worth the wait!
How to Serve Chocolate Zucchini Cake

Garnishes
A dusting of powdered sugar, a swirl of your favorite frosting, or a handful of extra mini chocolate chips on top will elevate your Chocolate Zucchini Cake from wonderful to unforgettable. For an extra flourish, scatter a few fresh berries or curls of dark chocolate.
Side Dishes
This cake pairs beautifully with a scoop of vanilla or coffee ice cream, or even a dollop of whipped cream. On cooler days, serve it alongside a hot mug of coffee or chai to make things extra cozy.
Creative Ways to Present
Try baking the batter as cupcakes for parties or lunchboxes—the perfect portable treat! Alternatively, cut your Chocolate Zucchini Cake into neat squares and stack them with layers of whipped ganache for a show-stopping dessert centerpiece.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, simply cover the cake tightly and refrigerate for up to 5 days. The flavors actually deepen after a day or two, making each slice even more delicious!
Freezing
To freeze, slice the Chocolate Zucchini Cake and wrap each piece individually in plastic wrap, then seal in an airtight container or freezer bag. It’ll stay fresh for up to 3 months—just thaw overnight in the fridge when the craving hits.
Reheating
Enjoy this cake chilled, at room temperature, or gently warmed in the microwave for about 10–15 seconds for that soft, fudge-like texture. If adding frosting, wait until after reheating so it stays smooth and glossy.
FAQs
Can I taste the zucchini in Chocolate Zucchini Cake?
The zucchini isn’t noticeable at all in the final cake—it simply melts into the batter, creating an ultra-moist and tender crumb without adding any vegetable flavor.
What’s the best way to blot the zucchini?
After shredding, spread the zucchini out on a clean kitchen towel or a few layers of paper towel, and gently press to absorb excess moisture. Proper blotting helps prevent a gummy cake texture.
Is this recipe adaptable for gluten-free or vegan diets?
Absolutely! Use a gluten-free flour blend and make sure to pick dairy-free chocolate chips. Since this cake is naturally egg-free, it’s already friendly for vegan and egg-allergic bakers.
Can I make cupcakes instead of a cake?
Yes! Simply divide the batter among muffin tins lined with cupcake papers and bake for around 18–22 minutes until a toothpick comes out clean.
Should I frost my Chocolate Zucchini Cake?
It’s delicious either way. A basic chocolate or cream cheese frosting takes it over the top, but it’s equally delightful with just a sprinkle of powdered sugar for everyday snacking.
Final Thoughts
I hope you give this Chocolate Zucchini Cake a spot in your baking rotation—it’s so easy, moist, and rich that it just might become a new favorite in your kitchen. Don’t be surprised if everyone asks for the recipe, and maybe, just maybe, forgets there’s any zucchini in it at all!
