Adding shredded zucchini to cake is a healthy way to hide some veggies in your diet, without compromising on taste- You won’t be able to tell that there is any zucchini in it!

Adding zucchini to chocolate cake is not only a great way to add nutrients to the recipe (fiber, vitamins, and minerals), but it also helps yield a fudgier and moist cake.

It’s also perfect to use up lots of lots of zucchini in one go- You can easily shred 3-4 medium-sized zucchini and incorporate it seamlessly.

Depending on which mix you use, you could technically add some into it, however, you will have mixed results.

It’s always best to add zucchini to chocolate cake recipes from scratch, as you can easily alter the liquids to compensate for it (e.g. milk or syrup).

  1. I don’t really have similar taste buds to my family, except for my dad. We both are obsessed with peanut butter. I used to think he was weird for going at the jar with a spoon. I’ve been changed 🙂 I love zucchini in baked goods, these look great!

  2. This looks very good!
    I shall be trying it. My Mama (92) hates zucchini so I try to hide it in different dishes.

    I have to comment on your Bio.
    You said you had been to North America and Canada.
    Canada is IN North America…..the USA does not own all of the continent.
    I assume you were saying you had been to the USA and Canada.

    :~D

  3. Still need to try making a protein frosting! I’ve often made veggies disappear in baked goods by blending them with the liquid before mixing. Cheese grater is a great idea though – less clean up!

  4. Sign me up for a big slice of this please, Arman! I feel like zucchini is my totem vegetable, if that’s a thing. I am always putting it in everything, since it seems to actually taste great in everything, I’ve discovered! Now every time I say “guess what’s in it!” to my other half, he immediately answers “zuccchini!!” with (false) enthusiasm 😉 I love the sound of that protein icing too! I bet it would be delicious on so many other baked goods too!

  5. In some ways yes, in some ways no. Unlike my family I HATE the taste of traditional Vietnamese desserts. Unlike me, my family hates the taste of sweet potatoes and peanut butter together! We fit each other soooooooo well. I feel as if this zucchini cake was one of the goodies you gave me right before you went back home, and I thought this was so delicious when I first tried it. If this zucchini cake is it, then let me tell you that I NEVER EVER would have thought zucchini was in it. 😉

  6. Oh man, I used to spend hours as a kind hunting for Waldo! Hours I tell ya. Now I clearly need to spend hours hunting for the zukes in this cake. And of course, I’ll have the eat the parts that are determined to be “waldo-free”. That’s the fun part! 🙂

  7. I’m allllll about sneaking zucchini into everything right now, because I’ve basically crowned myself the queen of volume eating. If I can eat more food for less, count me in. Especially if it involves chocolate and cake AND breakfast.

  8. Oh good gravy. This is going to the top of the list. Perfection!!
    Ps – thank you so much for putting the quantity of oats AND oat flour. Sometimes when I just have the pre made flour I don’t know how it will convert.

  9. “You could give her the most delicious chocolate brownie ever and she’d be a huge fan….until you tell her it’s made with black beans” -> this could be Stefan!
    I am intrigued by baking with zucchini but I never tried it before. Maybe I conduct a little experiment and try if Stefan would notice. I never got away with bean brownies.

  10. oh wow! This looks delicious! I will have to make your Paleo option tomorrow! Thank you for sharing and for including the Chocolate Coconut Whipped Cream link! So glad you enjoyed it! I loved making bread/cake with coconut flour as it tends to be very light and spongy! Xoxo, Ester

  11. Hi Arman, Greatings from Malta. Ready and in the oven. Cannot wait to dig in. After the success of the lemon and poppy seed breakfast cake I had to try out a chocolate one. Even my chocoholic son enjoyed the lemon cake. I love your blog, your recipes are so easy yet they taste great.
    Keep it up!!

    1. Hello Allison- Welcome!!! My friend is in Malta right now and she’s sending me photos of the amazing food there- I am so envious!

      Thank you so much for your kind words, hope you both continue to enjoy them! 🙂

  12. I would like to make it with oat flour, but use applesauce for the sweetener. Not clear on how to measure everything.What do you suggest?
