Chocolate zucchini cake has always had a special place in my heart as a family friend's mom made it specifically for me anytime I visited. She always made me feel incredibly special, making a cake upon my arrival. It was a simple gesture, but for some reason it made me feel more celebrated than even my birthday because it was a gift that was done just because she wanted to.

While I have been making a version of her cake for years, and even served one at my bakery that was a best seller, they have always included eggs. But, recently, I've stopped eating eggs as often. So, I knew I wanted to make a chocolate zucchini cake without eggs so I could still make this nostalgic cake for myself. And let me tell you, this chocolate zucchini cake does not need eggs!

Ingredients

individual ingredients for pumpkin spice chocolate zucchini cake without eggs laid out against a white background.
  • Zucchini: I use organic zucchinis, which gives this chocolate cake an incredibly moist and fudgy texture. Be sure to use a fine grater, don't use a large one as your cake can become gummy if the zucchini is not finely grated.
  • Olive Oil: I use organic extra virgin olive oil, making this cake free of seed oils.
  • Light Brown Sugar: I use homemade light brown sugar for added richness.
  • Dutch Cocoa Powder: I use organic Dutch cocoa powder for a rich chocolate flavor.
  • All Purpose Flour: I usually use organic all purpose flour instead of cake flour when making cakes with fruits of veggies. These will add more moisture to cake, so I like the higher protein content as it gives the cake more structure.
  • Baking Powder: Use baking powder, not soda as this is a slow rise bake. Be sure to check out my post the Difference Between Baking Soda and Baking Powder for more info on leavening agents.
  • Butter: I use organic salted butter for the frosting, but you can easily make this cake vegan by using your favorite vegan butter for the frosting too. Check out the Best Salted Butter for Baking.
  • Pumpkin: I use organic pumpkin puree as an egg replacer. This creates an incredibly moist and fluffy cake without eggs!

Make a Vegan Chocolate Zucchini Cake

You can easily make this a vegan chocolate zucchini cake by using your favorite vegan butter and milk in the frosting. This is naturally a vegan chocolate zucchini cake, so just swap out the dairy for vegan options in the frosting. I recommend using Miyoko's vegan butter with sea salt and coconut milk, which is what I used at my bakery for the best flavor in our vegan cakes.

Baker's Tips

  • I use organic extra virgin olive oil as I love the flavor here and it makes this cake free of seed oils. But, you can use canola oil if you prefer.
  • I use a mixing bowl and a hand mixer for the cake, but this one bowl chocolate cake is incredibly flexible. You can mix it up with just a whisk and spatula. Or you can also use your stand mixer.
  • Make this a vegan chocolate zucchini cake by using vegan butter and coconut milk in the frosting, the cake itself is already vegan!
  • I use my stand mixer to make the frosting as I think it's so much easier, but a hand mixer also works too.
  • Store extra cake in an airtight container in the fridge.

Recipe FAQ's

Why is my chocolate zucchini cake rubbery?

If you use a large grate on the zucchini, this can lead to a gummy or rubbery texture. Always use a fine grater whenever grating zucchini for cake. This way it can combine into the cake well and provide moisture and a delicate texture and crumb.

What binds a vegan cake?

Pumpkin is a great binder for vegan cakes. It works beautifully in this Pumpkin Spice Chocolate Zucchini Cake!

Can I make this vegan chocolate zucchini cake into a layer cake?

Yes. For a 6-inch layer cake, you can just separate the batter into two 6-inch. cake pans instead. You'll need to bake a little bit less, start with 20 minutes, check and go from there. For a layer cake that is larger, just double the recipe and you can stack the two cakes for a layer cake.
