I wanted these to be brownies, I really did. They are not. These are chocolate zucchini cupcakes. They are cakey and tasty, but not thick, gooey brownies. I knew right away when I saw how the batter turned out. I am still in search of the ultimate brownie recipe, and a girl at work just told me that she has one, and it uses shortening. Oh my gawd. Shortening. Not sure if I can venture into that evil area of baking.

I digress. These did not turn out as brownies, but they were tasty little cupcakes. And to be honest, most seasons we NEED a vast repertoire of zucchini recipes, so I will add this one.

They would be very good with melted chocolate drizzled on top, (but really, what ISN’T good with melted chocolate on top?)  and would be fantastic with some vanilla or chocolate icing! And then again, what isn’t fantastic covered in chocolate icing? I would eat a boar’s hoof if you put enough chocolate on it.

Zucchini Cupcakes Tips and Tricks

  • Serve these zucchini cupcakes plain, or with icing, or you can put the mini chocolate zucchini cupcakes in a mini mountain and drizzle melted chocolate chips on them. I would even go crazy and put my Buttercream Frosting on them or for a double chocolate does, my Chocolate Buttercream Frosting!
  • Make sure that if you are using an older, larger zucchini that you don’t use the seeds, just shred the outer part!

Freeze The Leftovers!

Muffins/cupcakes will keep in a closed container at room temperature for about four days, or frozen for up to two months. You could even make a double batch and stock your freezer for later!

    So i’ve just got mine in the oven. I was out of sugar so used 1/2 a cup of my brother’s chai tea mix and a teaspoon of stevia to replace the other cup of sugar called for. And after getting distracted multiple times finally got all the dry mixed in the wet and thought i had added a cup too much gf flours. So not really thinking about the action of tea leaves and low mass stevia I decided my mix was too dry and threw in an egg. Hoping for the best!

  2. Makayla says

    I did squeeze the juice from the zucchini and realized when mixing I probably should have left it in. But I let the zucchini and sugar sit a couple minutes and it was juicy enough. When I took them out of the oven and let them cook they were delicious. Taste and texture of a two bite brownie. Love it!!5 stars

  3. Andie says

    Followed the recipe exactly… they were moist, chocolaty and delicious! Best I have ever had. And a great way to use up all of my garden zucchinis. Follow the recipe! They were so good I made a second batch a week later and froze them. Quick few seconds in the microwave to reheat, tasted like they just came out of the oven. I did make larger cupcakes and they took 21 minutes at 350, but oven temps differ5 stars

  4. Mrs. M. says

    Couldn’t believe there were no eggs but they turned out great! Followed the recipe exactly as it’s written and frosted them with buttercream frosting…delicious!!!5 stars

  5. Komal says

    I wouldn’t recommend this recipe. It has too much baking soda. The recipe needs to be altered to 1/2 tsp baking soda and 1tsp baking powder.

  6. Sydney Nelmes says

    I thought the same thing when I saw that their were no eggs or milk, But after waiting about five minutes after I put the zucchini in there was a lot of moisture and the cupcakes turned out perfectly. I will definitely be using this recipe again.4 stars

  7. Katrinia says

    I had to bake these longer and finally took them out after 30 minutes; they were still soft on top. They tasted a bit salty, not sure what I did wrong.

    • Patty says

      Just made these cupcakes…larger ones and took 21 minutes…I f think they are delicious especially with the buttercream frosting!5 stars

  8. Desiree says

    Do not squeeze the zucchini! I repeat this doesn’t need eggs or milk, the zucchini liquid is what it needs !!
    I did that mistake , added some soy milk ( dairy and egg allergies ) and it was perfect.5 stars

  9. Jamie says

    I made these exactly as the recipe calls. Moist and delicious. Will use again.5 stars

  10. Krysten Bucknell says

    Very dry. I added an egg, mixed it all, then added approximately 1 cup of milk. It was still a little dry, had a fudge texture but baked very nice 🙂 end results were delicious!

  11. Catherine P says

    I followed your recipe, thinking “no eggs?” However I trusted you and went along. They were great! And if you get vegan chocolate it’s a great vegan snack. Not that I am vegan, I would like to try it with eggs maybe it will turn into a brownie!?!?

  12. Carmen says

    Are there supposed to be eggs in this recipe? Please reply! I have a giant zucchini I would like to use up! Thank you!

  13. Jo Feeman says

    This recipe seemed incomplete to me, so I added 2 eggs and a small container of vanilla yogurt, and they turned out great 🙂

  14. Mary Romanowski says

    The batter is extremely thick…should there be additional liquid? They are is the oven. ??

    • Melissa says

      How did they turn out? I guess you rant supposed to squeeze the liquid out of the zucchini?

      • Babs says

        The batter was extremely dry and crumbly. Needs more liquid, so I added a bit of milk, an egg and some sour cream. It was a good thing my zucchini was juicy. After all that the batter looked right. I am only giving 2 stars as we should not have to add so many extra ingredients to a recipe.

    • Nancy Armstrong says

      I love this recipe, I think I added 3 cups zucchini, also chopped walnuts

  15. ciaochowlinda says

    What a great way to present these cupcakes. Love the dribbling chocolate topping.

    5 stars

  16. ABowlOfMush says

    Lovely! I could eat thousands of these, they look very delicious.

    5 stars

  17. chocolate shavings says

    I made similar cupcakes/muffins a little while ago – I love how the zucchini is not only a healthy addition but also makes the batter that much more moist

    5 stars
