This is the BEST Chocolate Zucchini Cake! Perfectly moist, rich and fudgy and loaded with zucchini (but you’d never know)! Topped with chocolate whipped cream.

I’ll admit, I don’t eat a lot of zucchini that’s not in baking.

These Banana Chocolate Chip Zucchini Muffins are a favorite, but this rich and indulgent Chocolate Zucchini Cake is at the top of our list.

The texture is light and soft but incredibly moist, and it’s loaded with chocolatey flavor.

It’s also loaded with shredded zucchini (a whopping 3 cups!) but you’d never know, and you’ll probably never even see it.

This cake is perfect for making ahead and taking to any barbecues, potlucks or picnics you have going on this summer (just top with whipped cream before serving or keep chilled)!

It’s also perfect for hiding in a corner with the pan and a fork and not sharing with the kids, your choice 😉

How to make Chocolate Zucchini Cake:

This cake is made conveniently in one bowl, so we get to save on dishes, too!

  • Whisk together the sugar and wet ingredients — this helps to prevent a grainy texture.
  • Add the cry ingredients and whisk just until thoroughly combined
  • Stir in the zucchini — some recipes call for drained zucchini, but I like to shred it and throw it right in! The moisture if the cake depends on all that juicy goodness
  • Spread into a 9×13″ pan and bake until a toothpick comes out clean or with moist crumbs. As long as you don’t see batter, it’s good to go!
  • Let cool completely before topping with the whipped cream. If you’re not serving that day, it’s best to top with whipped cream just before you are going to eat it.

Ingredients and Substitutions:

  • Buttermilk: buttermilk gives this cake a light and airy texture and I recommend using buttermilk if you have some, or see my post on How to Make Buttermilk if you don’t! If you are looking to make this cake dairy free, I think a dairy free milk of your choice would work just fine, but I haven’t tested it.
  • Eggs: I haven’t tested any egg replacements in this recipe, although I have used flax eggs in other cakes and they have turned out well.
  • All purpose flour: If you want to make this cake a little healthier, feel free to swap some or all of the flour with whole wheat flour. I don’t think you’d even notice!
  • Whipped cream: The chocolate whipped cream on here is one of my favorite parts, but you can substitute with whipped topping, chocolate frosting, or just sprinkle with a handful of chocolate chips before baking. Opting for chocolate chips makes it even easier to transport if you are planning for a picnic!

      Hi! It’s definitely okay to make ahead of time. Cake can be stored in an airtight container at room temperature for up to 4 days.
