These easy zucchini brownies come out rich and chocolatey and stay moist for days (although they don’t last that long in my house). They’re topped with a quick and easy homemade 1 minute frosting for a perfect dessert!
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.
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 *

One of my favorite zucchini recipes.
I have tried lots of zucchini cake/ brownies recipes and this is the one my family begs me to make!
So good. Moist, rich. We use it for birthdays.
I just took out of the oven what I thought was going to be brownies. it was just liquid. recipe calls for three cups sugar. That is not correct. I looked at other recipes and they call for half that.
I am really upset by all the ingredients I will throw out. I have been cooking a lot of years so its not that I can’t cook or follow directions. How many more have used the three cups of sugar.?
This recipe calls for 1 ½ cups of sugar in the brownies, not 3 cups. As written, I’ve made this countless times and it does work well for most readers. Hope that helps.
I have done this recipe for over 7 years I guess and still is our favorite. I can’t thank you enough for sharing this great recipe.
can I use box brownie mix and add zucchini and follow your recipe
I have never tried a boxed brownie mix so I can’t say for sure. Maybe another reader has and can offer some guidance.
This is the best chocolate cake ! The family wants it every week
brownies are really good and moist
icing is too sweet I might just put cup of chocolate chips on warm brownies
next time instead of making the frosting
I love melting chocolate chips on top of my brownies too, Carol!
Main page says 3 c sugar and when clicking on recipe it says 1 1/2 c-ugh! I always make these and just assumed the recipe was correct when I googled it. Just an FYI to fix
Hi Cindy, Thanks for letting us know! The recipe card lists 1 ½ cups of sugar (which is the correct amount). I hope that helps.
These brownies are delicious!!
