This is the best Chocolate Zucchini Cake, ever. Totally moist, full of amazing flavor, and destined to be your go-to recipe! Even if you just make the cake part of the recipe, you will be blown away by how dense and rich it is!
Zucchini Double Chocolate Cake
And while I did add poured chocolate ganache AND piped chocolate ganache… the truth is that this cake really doesn’t need any frosting at all.
All on its own it’s full of rich chocolate flavor and a delicate and glorious crumb.
In spite of its stand-alone amazingness, I went a step further. Well, a couple steps further.
I added not only a beautifully poured ganache but a whipped ganache!
While this recipe is definitely all about the beauty of a perfect chocolate cake, I couldn’t help myself. I was mesmerized by these sweet little whipped ganache stars.
Tips for Success:
- Let’s talk zucchini: I typically leave the peeling on because I happen to love seeing little flecks of green through my dessert. You can certainly peel yours if you do not want to see any trace of the vegetable. If you do end up peeling it, people will never know there is zucchini in your cake… unless you tell them of course!
- When peeling zucchini I try to choose the smallest size on the grater. I also did not drain my zucchini for this recipe. It benefits from all the moisture the zucchini offers. The level of moisture varies depending on the size of the zucchini… the bigger the zucchini the less moisture.
- I chose a rich, dark, bold coffee. Here is where I am going to be a bit bold myself: No. No, you cannot replace the coffee with hot water. I mean, yes, of course, you can, but NO you do not want to. The cake will not taste like coffee in the slightest, I promise. It simply enhances the chocolate flavor. If you replace the coffee or simply omit it, your cake will not taste as rich.
- I followed the recipe above for my pourable ganache… but then I made another batch. And when that batch had cooled I whipped it and added 3 cups of powder sugar. Working quickly, I piped the mini stars on top of the cake. (The frosting stiffens the longer it sits.)
PRO TIP: Put the frosting right into a disposable pastry bag for storage as well as easy use!
It is just as moist and rich as you would imagine it to be. More even.
This is definitely my new go-to Zucchini Chocolate Cake!
Can we just look at the frosting again?!?!

- 1/2 cup (99g) vegetable oil
- 1 3/4 cups (350g) granulated sugar
- 1 tsp. vanilla extract
- 1 tsp. baking soda
- 1/2 tsp. baking powder
- 1/2 tsp. salt
- 2 large eggs
- 1/2 cup buttermilk
- 2 1/2 cups all-purpose flour
- 3/4 cup cocoa powder
- 1/4 cup hot coffee (or espresso)
- 3 cups shredded zucchini
- 1 cup chocolate chips
Ganache
- 1 cup (225g) whipped cream
- 2 cups (350g) semi-sweet chocolate chips
Instructions
- Preheat the oven to 325°F. Lightly grease a 9″ x 13″ pan.
- In a large mixing bowl, beat together the butter, oil, sugar, vanilla, baking soda, baking powder, and salt until smooth.

Ganache
- Place the chocolate into a medium bowl. Heat the cream in a small sauce pan over medium heat. Bring just to a boil, watching very carefully so that it does not boil over.

What can I replace egg with??
Your recipes look delicious!
Since I am 89 years old I do not do much baking but in my dy I had a desert on the table almost every night.
My favorites are pies and I still make our Thanksgiving pies for our family gathering.
Thank you for sharing all the delicious recipes with us.
Looks delicious! Just wondered – do you use a chopped chocolate bar for the Ganache, or chocolate chips? In the ingredient list it lists chocolate chips, but in the instructions it mentions chopped chocolate. Thank you!
Very good, although a bit rich with ganache. Was wonderinf if this would freeze well for a month or so?
Hi, Patty! I work with iambaker and am happy to help with questions. Yes, you could freeze this cake. Let the cake and ganache cool completely before freezing it. Wrap it tightly in plastic wrap and aluminum foil, or you could use an airtight freezer-safe container. Label and date it, and it should be fine for up to two months. Have a great day!
i love all your recipies
this came out pretty good. 🙂 my wife cut it down to two cups of baby marrows (juice squeezed out) and we didn’t do any icing/ganache on top. i baked it saturday and by sunday we only had 2 little rectangles left (cut the cake into 16 pieces). we also gave 4 pieces to the neighbours, but regretting that decision now.
This is by far one of the best cakes I ever made. You cannot taste the zucchini at all. Sometimes you get little bites but it is so good. I have already made this cake twice in a week.
Can I make this cake in a bundt pan? Thank you!
This zucchini chocolate cake is so decadent an moist. It is my favorite chocolate cake and will replace all other chocolate cake recipes.
