If you’ve never added zucchini to your baked goods drop everything you are doing and do it now! These Zucchini Brownies are unbelievably moist and rich. A chocolate lovers dream! Be sure to try my Zucchini Cake and Chocolate Zucchini Cake! (and if you want a zucchini-less brownie recipe, try this one!!)
Zucchini Brownies
When I first made these Zucchini Brownies in 2012 I declared that I would never need another brownie recipe. They are the BEST brownie I have ever eaten, hands down. But, zucchini is very much a seasonal product, so having a great brownie recipe that doesn’t have zucchini is important. Every summer I am reminded just how magical zucchini is in baked goods and these become my favorite again!
When using zucchini in recipes there are a couple tips & tricks help to make sure your baked goods are perfect!
-Use the fine side of your grater. Coarser pieces will have a slightly more noticeable flavor and texture in a finished cake or bread recipe. (Farm kids tend to want that!)
-Some recipes ask that the zucchini is pressed well with a clean towel to soak up excess moisture or to prevent whatever your baking from getting too soggy. Pay close attention to the recipe that you are making with zucchini as the level of moisture they provide is important. For instance, in this recipe, the zucchini is the main source of moisture and should NOT be drained!
Double Chocolate Zucchini Brownies
This recipe is going to test any experienced bakers boundaries as it does not act like a normal brownie.
The batter is DRY. Extremely dry. Until you add the zucchini that is! Assemble the batter according to the recipe instructions and then let it rest for 5 minutes. Stir again and you will see how much moisture the zucchini adds!
I added semi-sweet chocolate chunks to this batch to make the double chocolate. You can add milk chocolate chips, peanut butter chips, white chocolate chips, or no chips! They are so good and so rich the extra flavor is not necessary. (But can be fun!) If you do use chocolate morsels instead of chunks, be sure to use 1 1/2 cups instead of 1 1/4. Reserve a few for the top too!
As you can see, the zucchini bits practically disappear into the glorious chocolate layers. If you don’t tell people, they will never know you added a full 3 cups of this abundant vegetable!
Eggless Brownies
You will notice that there are no eggs or butter added to this recipe. They are absolutely not needed! These Zucchini Brownies bake up beautifully (almost cake-like) and do not need the added air and flavor that eggs usually add. This is a great recipe for vegan friends!
Another bonus? This recipe can be made in 1 bowl!

These turned out good but I would call this a chocolate cake, NOT brownie. Staff at work seemed to like it 🙂
I like
These were amazing! I think mine must have been a bit more undercooked from what others are commenting because mine came out very brownie like. We refrigerated ours and it made them even more delectable!!!! I actually wonder if maybe they were a bit undercooked? They were moiste and even kind of fudgy in the middle after being in the fridge. AMAZING! My husband and kids loved them and I’m taking them to work tomorrow! (And a 2nd pan for the family) a great way to use those giant overgrown zucchini!
They must have been cooked perfectly because mine always turn out that same as yours did!! 🙂 So glad you all enjoyed them!
Can I use frozen zucchini in this recipe? Freezing zucchini makes it watery once thawed.
I have not ever used it frozen so can’t speak to it effectiveness.
Live this recipe! Can’t wait to try it.😊
Any nutritional facts for these
These brownied are DIVINE!!! I had a ton of overgrown zucchini and was looking for a new recipe. This is my go-to brownie recipe now! Thank you for posting this yummy recipe and the zuchhini chocolate cake recipe–both are fabulous!!!
This gonna be good! Loved the texture during prep. I’ve never baked a brownie in my 68 years of life. Zucchini is from the garden and all will be ready for our little Logsden Community Harvest Auction and get together! Thank you for the inspiration. I have four minutes left until removal from the oven!
I have never commented on any recipe before. But THESE!
Even my 1 year old who is turning into such a picky eater loved them. They are even better than regular brownies in my opinion.
Love it Gina!!
Hi, my coworker made your brownies and they are AMAZING! I am not typically one for alternative food options but I LOVED these. With that being said, my boyfriend may be gluten intolerant and I wondered if I could substitute rice flour or corn flour to make these for him?
Just fabulous!!!! Will be making again.
Not good…weird texture…not recommended. Husband says I tried to make pudding in the oven…sorry…won’t make this one again
I don’t like Zucchini… it will be good if I did not use it??
Followed the recipe exactly, and came out with some of the most delectable brownies I’ve tasted. They have a very rich chocolate flavor, and are extremely moist. The zucchini is almost completely undetectable if you grate it finely as the recipe suggests. Will definitely be adding this gem to my arsenal. Thank you for sharing, Amanda!
I made this today and munching it right now. So yummy, moist and chocolatey. I used Lakanto Monks Fruit sweetener in place of sugar and used half Mochico and half APF. Chewy and yummy. It was still a bit too moist after baking it 50 minutes so I let it cool first then I put it in the ref to firm up. It worked. Love it!!!
