Every year I end up with tons of zucchini which is great for me because I really love it!  It’s perfect grilled on it’s own or breaded to make oven baked zucchini fries but I do think it’s especially good in baking. It just adds so much moisture and it seems that baked items with zucchini are even BETTER the next day!

These brownies are super moist and delicious… and you’d never know they have zucchini in them (nor will your kids)!  They are rich and chocolatey and just perfectly delicious!  Of course these Zucchini Brownies are great the day they’re made but they’re even better on the second day.

Easy Zucchini Brownies with 1 minute Frosting! These are quick to make... and the zucchini keeps them so moist and amazing! The frosting.. ridiculously yummy and ready in just one minute!One thing you need to know about this recipe is that when you get the flour/sugar combined… just before you add the zucchini the consistency will seem quite dry.  Don’t worry, this is expected.  Stir in the zucchini and your batter will moisten and as the batter bakes the zucchini releases moisture keeping these brownies amazing. You’ll want to make sure you don’t squeeze or drain your zucchini, you want all of the moisture in there (and no peeling required either)!

I top this with a 1 Minute Frosting recipe that I’ve been using for years!  It works perfectly on any cake or brownie recipe that is contained in a pan and requires just a few ingredients you likely already have on hand!

Items you’ll need for this recipe:

* Vanilla Extract * Zucchini * 9 x 13 pan *

  1. Thank you so much for the great recipe. I followed the recipe exactly the first time I made them and they were delicious. I just made them again with a little peanut butter in the icing and it was great that way too.

  2. Great dessert and quick to make . My brownies were moist . 

  3. Really no salt at all?

  4. Amazing! These turned out so moist and delicious. I followed the directions exactly and the results couldn’t have been more perfect. The frosting was to die for. Thank you for sharing your rexipe. I will be making these again for sure.

  5. I used warmed coconut oil as a vegetable oil replacement (something I have done successfully with many other recipes), I found the batter was extremely dry. I had to use my hands to knead the dough, it’s like a dry pie dough. I continued with the recipe as is and pressed the dough into the dish. They baked just fine but I could taste the baking soda (even though I shifted the dry ingredients together before adding it to the wet mix). I found another recipe online that was almost exactly the same except that it called for 1 1/2 Tsp of Baking Soda and it didn’t have this “so-called” one minute frosting (more like 5 to be honest). The frosting is more like fudge, if it wasn’t for the fudge topping these would have been a complete waste. Just because you have mixed Zucchini with a total of 3 cups of sugar, almost a cup of fats and a cup of chocolate chips, doesn’t make this Healthy in anyway. Don’t fool yourself into thinking any brownie is Healthy. If you choice to proceed with this recipe, I suggest you cut the Fudge frosting recipe in half and cut down on the Baking Soda.

    • This recipe doesn’t make any claims to be “healthy”, it’s a dessert and it contains sugar and fat. Please keep in mind that making substitutions in recipes (especially baking) can alter both flavor and texture in a recipe. If you read over the comments, you’ll see that readers following the ingredients provided in the recipe seem to have good success with these brownies. I hope that helps.

  6. I made these today and can’t wait to try them!
    The batter threw me as it was so dry so I took my rings off and dug in with my hands and then it came together perfectly! 

  7. These were delicious! Our family favorite zucchini recipe!

  8. So good! Keep the recipes coming!

  9. Oh my gosh these were incredible!  The brownie was moist and not too sweet. The frosting gave it the proper sweetness. These were amazing!

  10. These brownies were moist and delicious!

  11. Hello. Is it possible to substitute a different vegetable for the zucchini in these recipes? If so, what substitutes would work best?

  12. What a fabulous idea. Love the idea of incorporating zucchini into the recipe. I’ve been craving brownies and came across your recipe. Will be making these today…. can I use butter in place of oil? Thank you ☺️

    • I haven’t tried butter in place of the oil in this recipe. If you try it, I’d love to hear how it works for you!

      • Oh my, I followed the recipe exactly as written. These are the BEST brownies ever. So chocolatey, and moist. You can’t tell that they have zucchini in them. Next time I make them I’ll use butter in place of the oil just to see if it make a difference in taste. This will definitely by my go to recipe. Doing my happy dance

  13. Husband is diabetic and wants me to use stevia or Splenda in place of the white sugar. Will this work for these brownies and what would be the conversion of either for the white sugar?

  14. This is a great recipe. I am making it for the second time for a family dinner. Thanks for adding that the batter would be dry as I would have probably added liquid and it wouldn’t have turned out. The frosting was so good!

  15. These sound delicious. I have always enjoyed zucinhini bread. I can’t wait to try the brownies and some of your other recipes.

  16. If I’ve shredded and frozen my zucchini before hand and I want to use it for this recipe there is a lot of water in the bag. Should I still add this water to the recipe or should I drain it out first?

  17. Can u please give me the complete nutritional value for your zucchini brownies thank you

  18. What is the best way to store these? And how long will they stay?

    • We leave them covered on the counter for about 2 days. If it’s going to be longer I would suggest storing them in the fridge as the zucchini makes them very moist.

  19. Very late to the zucchini brownies train, atleast I am about to try bc I reallly want zucchini brownies!!; So would 1\4 cup of butter work bc i dont use vegetable oil !?

  20. Followed the recipe, but added in some chocolate chips to the batter. Turned out excellent! I took some into work, and everyone loves them!! Will most definitely make these again, and keep this recipe on hand. Thank you so much!! Out of curiosity, what would the calorie count be? I cut mine into maybe 1 1/2 inches by 1 1/2 inches.

    • I’m so glad you (and your co-workers) loved them! :) I don’t provide calorie counts but you can easily plug in the link over at MyFitnessPal.com Just head to the food tab and click recipe. You can just add in the link and it will give you the info. Hope that helps!

  21. Hmm, not sure why these didn’t work for you. Did you drain your zucchini first? The moisture in the zucchini is needed to keep the recipe moist.

  22. Can I use Organic Brown Sugar instead of regular white sugar?

  23. I used frozen zucchini that I had in my freezer, and this definitely turned out to be a cake. Still delicious!!!

    • That’s interesting, I’m glad it was still delicious! I wonder if it had to do with the water lost during freezing. Did you defrost your zucchini first (and did it lose a lot of water)?

  24. I have made these before and they are simply wonderful! I was going to try making them in muffin cups this time so that they are easier to transport (via mail-I mail care packages to my son at school)…has anyone tried that? Wonder how it will change the baking time?? Any suggestions?
    Thanks!

  25. I have never tried a zucchini brownies, but that frosing has got me hooked!

  26. Zucchini brownies are a great idea in the summer too, when I have an abundance. YUM.

  27. Love this recipe. Have made chocolate zucchini bread before, the frosting looks decadent and QUICK! Woo hoo!!!

  28. I’m loving this recipe! I have zucchini in the freezer to use up!

  29. love the hidden veggies in this!!!!!

  30. I love recipes like this! Throw zucchini in all the things!

  31. Have you tried freezing these? I want to make them for the weekend but won’t have time or space to do it the day of. Was thinking I’d bake the brownies, cool, then freeze. Then the day I need them I’d thaw them and make the icing. I freeze a lot of baked goods to keep them moist and fresh but wanted to see if anyone tried freezing this recipe…

  32. These are great – thanks for the recipe! I added chocolate chips to the brownies and some cream cheese to the frosting. It was a big hit!

  33. These look delicious! Would you have any recommendations for substituting the egg? Can I make it without it? Thanks!

  34. Oh my I just made them this evening they where absolutely the best brownies ever! Thanks for sharing.

  35. Oh my!! Best brownies ever!! Thank you :)

  36. Can I use yellow zucchini on these, and does it need peeled?

  37. I just made these and they are awesome. I ran a little short on the zucchini and I was afraid that it would not be moist, but that is NOT the case. Very moist and delicious. I used a peanut butter whipped topping on them instead of the 1 minute frosting and it was a great combination too. Thanks for sharing.

  38. Just made this and while it turned out “okay”, it was somewhat dry. I did peel my zucchini but didn’t drain or squeeze the water out. I also used self-rising flour instead of all-purpose, as that’s all I had in the cabinet. The flavor is good, just that the cake is dry. I also used chocolate can frosting instead of making my own. Will def try again, but would like suggestions as to how to keep it moister next time!

    • Self rising flour does contain baking powder (and salt) which can definitely alter the texture of these making them more “cake” like and possibly drier.

      If you give it another try, there is no need to peel the zucchini and I would recommend regular flour. I’d love to hear how it works out for you!

  39. This sounds awesome. Do you peel your zucchini before shredding?

  40. Is this made with powdered sugar? I made the frosting with white granulated sugar and it is a little gritty. Tastes good though.

    • I used granulated sugar and mine seemed to work out well. I do love the idea of trying it with powdered sugar though… I’m going to give that a try!

    • The granulated sugar should work fine as you heat everything to boiling, that should dissolve the sugar!

  41. These sound really good plus it’s a good way to get some veggies into my kid! Thanks for posting it

  42. ummmm, these looks TO DIE FOR!

  43. Can’t wait to try these. Just wondering tho instead of the sugar, could I use honey..something with less calories…. I don’t use agave or sugar substitutes so I thought I’d try honey. It works when I make cookies…. And instead of Vegetable Oil I was going to try Coconut Oil..any suggestions? Thanks…

    • I have never tried it with honey so I can’t say for sure. If you do try it, please let us know how it works out.

      • Honey can be substituted for sugar. Because it is sweeter than sugar use less about a quarter cup honey for a cup of sugar Also watch the baking time as it may be shorter. Honey easily burns. It should work out okay. It is worth a try

    • Use plain applesauce in place of the oil, works great

  44. I used Dark Cocoa instead of unsweetened Cocoa, the only thing is it had a minty taste to it. I have no idea as to why that happened. I do not bake often. They were really good and I didn’t mind the minty flavor. What would cause that? Is it the cocoa I used or something else that causes that.

    Great recipe! Will be making this again.

  45. Your Zucchini Brownies sound delicious, and I love your One Minute Frosting!

  46. So can I consider these healthy brownies since there is Zucchini in them? haha! These sound delicious. I’ve yet to make a bread or dessert with zucchini but I really want to try it. I will be pinning this!

    Emily

  47. Yum. Pinning this so I can make it in the summer when I’m drowning in zukes!
