This quick and easy recipe to make a delicious chocolate zucchini cake with cake mix will become an instant summertime classic in your home! 
If you love chocolate zucchini cake but feel like you don’t have the time for all of the steps that it takes to bake it from scratch the old-fashioned way, then this 3 Ingredient Chocolate Zucchini Cake is for you! I came up with this zucchini cake with cake mix recipe in the spirit of my super popular 3 Ingredient Banana Bread and I was a little surprised actually that it worked just as well! What other 3 ingredient cakes are out there for me to discover next? I’m willing to be the guinea pig for this one and let you know as I discover them. 🙂
Chocolate zucchini cake is of course a great way to use up all that extra zucchini from your garden, but it’s also a really fun baking project to make with kids if you do it this way. It’s so easy and it comes together quickly enough that even the littlest helpers don’t have time to get bored or distracted and decide to start playing with the coffee maker instead.
So here’s how you make it!
How to Make Zucchini Cake With Cake Mix
Start with an abundance of zucchini!
2-3 small grocery store sized zucchini should work if you don’t have any in your garden, or you can get 1 large garden-sized one from a generous friend who has zucchini coming out of their ears this summer.
Here’s what you need for this recipe:
- 1 box of chocolate cake mix
- 2 eggs (or you can use chia eggs!)
- about 1.5-2 cups of grated zucchini, lightly packed
The grated zucchini can be a little hard to measure because it really depends on how much you pack it down in your measuring cup, but don’t worry. We’ve made this recipe with a little more and a little less zucchini and it’s always worked out just fine. We’ve been testing a lot of chocolate zucchini cake around here lately for you. 🙂
Mix everything together in a bowl until it’s thoroughly combined. If you feel like your mixture is a little on the dry side, add in 2-3 tablespoons of water, but don’t add too much because the zucchini will release quite a bit of moisture as it cooks.
Pour your batter into either 2 medium sized loaf pans or one bundt pan and bake it in a 350 oven for about 45 mins.
Just as Good or Better Than From Scratch
When it comes out, you’ll have something that is just as good or better than a chocolate zucchini cake made right from scratch!
I love how perfectly this turns out every time! It just has that super-chocolatey look to it that no one can resist!
Definitely add this one to your list of must-try recipes! Feel free to experiment too. Check out the comments section of the 3 Ingredient Banana Bread post for inspiration on what to add to your cake. Wow, do I ever have some clever readers!
