Chocolate Zucchini Cupcakes

Jump to Recipe

It’s that time of year where everyone is overloaded with zucchini. Our friend’s gave us a monstrous zucchini and I was determined to not let it go to waste. I made zucchini brownies, but that only made a small dent in the giant zucchini. I decided to make Chocolate Zucchini Cupcakes with the rest of the zucchini. You can’t go wrong turning a vegetable into a chocolate dessert:)

If you think adding zucchini to cupcakes sounds weird, gross, or just wrong, think again. These cupcakes are one of the most moist, rich, chocolaty cupcakes I have ever tasted. If you think no one will eat them because there is zucchini involved, just don’t tell them. It will be our little secret. One of the kid’s in our neighborhood stopped by and we gave him a cupcake. He licked his wrapper clean and had chocolate all over his face. I think he liked it:)

If you are wondering what to do with your garden zucchini, try these Zucchini Chocolate Cupcakes. And if you don’t have any zucchini, I am sure a friend or neighbor would be happy to share with you:) I am going to have to hunt down some more zucchini so I can make these cupcakes again. They are a new favorite!

  1. These are awesome! Very moist and tasty! No one knew they had zucchini in them, I even used the green sprinkles for presentation!

  2. Fantastic! My veggie hating 5 year old raved about these and bragged about how he made them! This made 30 cupcakes for us so we got to freeze some! thanks for a yummy recipe

  3. I made these cupcakes last night, while my husband was out and my boys were alseep. If they knew there was zucchini in these I think they would run. I was a little freaked out at the whole zucchini chocolate idea when I first read this post, but I love your other recipes and thought I’d give these a try. I’ll sneek veggies in where ever I can to feel less guilty.
    These cupcakes are SO good! They are rich and puffed up beautifully and made me very happy. The cinnamon smell in my house was wonderful. Thank you for this recipe!

  4. These look delicious! What do you recommend though if I don’t want to use eggs? I know there are many possible substitutes, but I’m not sure which is best.

  5. After multiple attempts to GIVE zucchini away I have decided to make desserts with all the zucchini I have. These are the most moist soft cupcakes I’ve tasted; so delicious!!! Thanks for sharing your recipe; definitely making these again this year!….and again next year! 😀

  6. This might be a silly question, but since I’ve never baked with zucchini before…… When you shred it, do you leave the skin on??

  7. I used this recipe to make cupcakes for my son’s school birthday treat. The only change I made was substitute 2/3’s of the oil with applesauce and I halved the frosting recipe. These were so delicious and I am definitely keeping this recipe in my rotation! Thank you for posting all those years ago!

  8. These sound delicious, and I will be making them when zucchini are in season here.
    Just one small piece of feedback – Plurals (friends, kids) don’t need an apostrophe.

  9. I have made these several times. Adults and kids have enjoyed them equally. Thanks for the great recipe. I love new ways to use my zucchini bounty every summer!
