This Chocolate Zucchini Cake with Chocolate Glaze is a deliciously decadent fall treat.
Whoever originally added shredded zucchini to a cake was a genius. It takes this simple chocolate cake to an extraordinary level – it’s so moist and decadent. Make this Chocolate Zucchini Cake for your next holiday party, and everyone will fall in love.

I love zucchini squash in bread, pasta, enchiladas, fried, floured, really any way you can prepare it, but my favorite to use it is in a cake! Specifically, Chocolate Zucchini Cake! It is easy to make, appealing to the eye and everyone loves it. By far, one of my favorite fall recipes.
I seriously love this cake, I have no idea why I don’t make it more often, it’s really perfect all year long. I got the recipe from my Aunt Patty – she makes the best desserts, and I’m so grateful she shares all of her delicious recipes with my family.
It might seem like a simple frosted chocolate cake, but it’s so much more than that. Rich, decadent, incredibly moist – the total package!
The only thing we changed with the original recipe was the amount of ganache frosting. I doubled the amount because the original recipe was nowhere near enough. I mean I can see why it would be fine….but the more ganache, the better, right?

Recipe Tips
Tip #1 – I’ve used grated and shredded zucchini for this recipe, and both work fine. Use a box grater or a food processor fitted with a grating blade. You don’t need to wring out the moisture from the zucchini. Just grate and add it right to the batter.
Tip #2 – Bake the cake a day in advance! Once you bake it, let it completely cool, then wrap it tightly with Saran Wrap. Then before you serve make the glaz; pour or use a spoon to drizzle the ganache over the top of the cake. Let it drip down the sides.

Ganache Frosting – so easy to make!
In a double boiler over medium heat, combine butter, chocolate chips, and corn syrup. Stir until completely melted and well incorporated.
Carefully turn the cake out of the pan onto a baking rack. Place a baking sheet or piece of parchment paper under the rack to catch the drips.


You can’t taste the zucchini in the cake – it’s added for the moisture and gives the cake the most incredible tender crumb. If you aren’t a fan of zucchini you might want to try my Triple Chocolate Pumpkin Cake.

Let me say it got rave reviews at my house. I mean, it’s chocolate cakeโฆ.Need I say more? Who cares that it has veggies?!
The kids didn’t mind the veggies and loved it! The only complaint I got was the audible “ugh!” when I gave half of the cake to the neighbors. There wasn’t a crumb left at our house. Enjoy! XOXO San
