This Chocolate Zucchini Cake Recipe is moist and rich with a deep chocolate flavor; you’d never guess it has 3 whole zucchinis!
When I was dreaming up this cake I had a decadent chocolate cake in mind.
Something really indulgent…sinful, even.
Then I looked in my fridge and found three pretty zucchinis that needed to be used up. Even despite making a few zucchini recipes lately, like Roasted Vegetable Crustless Quiche with Basil & Pine Nuts and Cinnamon and Nutmeg Zucchini “Applesauce”.
Seeing the zucchini I got an idea and I knew sinful would have to wait.
(Side Note: That is the beauty of keeping your kitchen stocked with healthy things. If they’re there, you’ll eat them!)
But the great thing is, zucchini happens to be a trick cake ingredient that will keep your baked goods moist without imparting a strong flavor.
In fact, I’ve found that the flavor of zucchini is easy to fully mask in cakes and quick breads. Especially baked goods like this one!
This Zucchini Chocolate Cake is full of flavor from ingredients like cocoa powder and cinnamon-orange black tea. If you have central air conditioning or are brave enough to bake in the heat, this cake is one worth making, especially if you have zucchini to use up.
Pro Tip: If desired, add 1 cup semisweet chocolate chips or 1 cup chopped pecans or walnuts to the batter.
Even though I wouldn’t consider this cake sinful (how can any food that has veggies be considered sinful?), it definitely does taste indulgent. Best of both worlds, perhaps?
Do You Peel Zucchini When Shredding?
For a lot of zucchini baked goods recipes, it isn’t necessary to peel the zucchini before shredding.
You can peel the zucchini before shredding or leave the skin on for this cake.
How to Store Zucchini Cake
Zucchini cake will stay good for about 1 week. You can store this cake wrapped with plastic wrap at room temperature for 2 days. After that, store it wrapped in the fridge for up to 5 days more.

Just made this cake and it was AWESOME!!!! I love that the zucchini is pureed, makes such a nice fluffy cake. Thanks for such a fantastic recipe!
G’day and YUM Faith, true!
What a GREAT way to use up zucchini and your cake looks so moist and love your photo too!
Cheers! Joanne
see–there’s no reason for all these zucchinis to go to waste. i hate when people let them rot when they could be making delicious things like this.
I’m not normally a big fan of zucchini but I’m sure I would love this cake – chocolate helps most flavours!
I love hiding some zucchini in baked goods, especially, just like you said, only few figure it out , especially when paired with chocolate.
Gorgeous photos Faith
What a delicious idea! Using orange cinnamon tea in cake. I just made Double Chocolate Zucchini bread and it didn’t quite mask the flavor of the zucchini but maybe I should try this cake with the remaining zucchini!
So weird…I just made a chocolate zucchini bundt cake flavoured with a little cinnamon. No orange, though! Great minds…
This does look every bit decadent to me. I’ve never used zucchini in my cakes and don’t know why…thanks for the idea and if my cake looked like this, why not infuse it with goodness.
This cake looks terrific! What a lovely texture.
Cheers,
Rosa
Looks and sounds gorgeous, Faith. It is certainly a nifty trick using tea bags to flavour cakes (I do chai, coconut and carrot muffins). I swear I can almost smell it while reading the recipe! Maybe I should go and eat breakfast :D
Faith, it sounds like a fun way to use zucchini! (A little more decadent than when I make Artichoke Zucchini Soup out of ’em.) And it seems like it would be a great party food- the caffeine in the tea might perk things up a bit, haha :D
This looks like a very delicious cake! Using zucchini in cake is such a great idea!
I’m loving this cake, the zucchini and spices sound wonderful with chocolate!
There is nothing quite like zucchini cake — and I’ve actually got a few extra zucchini hiding in my fridge, so now I know for sure what I’ll be doing with them. Love the addition of orange-spice and cinnamon!
Oh Faith this looks divine. I am making this for my dad’s birthday next week. Thanks for sharing. x
Looks super moist and amazing! Your pictures are always so beautiful
