If you follow me on instagram in peak harvest season, you may notice I have some serious zucchini baking days. One year, the zucchini plant growing in my garden went so crazy that I had more of this green veggie than I knew what to do with. The struggle is real, and I’m trying to find new recipes to make.

Zucchini Brownies

As much as we all love Roasted Zucchini as a side dish, I had enough zucchini to serve it as a side dish for a small army. After getting our fill of  Chocolate Chip Zucchini Bread and Zucchini Banana Bread, I was in the mood for something different. Something with chocolate!

Fortunately for me, I have lots of amazing, talented foodie friends. So, today, I took a shot at making my friend Audra’s recipe for Zucchini Brownies. Be sure to stop over at her blog, The Baker Chick, for some delicious peach cobbler, churro cupcakes, and margarita bars (these are happening soon!!).

And can I tell you guys…these were the bomb. They were rich and fudgy just how a brownie should be! There’s no hint of veggie flavor at all, I promise. And the frosting on top? I couldn’t have asked for anything better, it was absolutely perfect!

The only change I made with these brownies was to sub out some of the regular sugar for brown sugar and I used canola oil in place of the coconut oil in the original. These brownies are extra chewy which I love.

Chocolate Chip Brownies Recipe

Here’s what you need for the brownies: 

  • Zucchini – Grated (See my tips below for how to grate zucchini.)
  • Granulated sugar
  • Light brown sugar – Or more granulated sugar if preferred
  • All purpose flour
  • Vanilla
  • Canola oil
  • Unsweetened cocoa powder
  • Baking soda
  • Salt

To make the chocolate frosting, you need: 

  • Butter – melted
  • Powdered sugar
  • Unsweetened cocoa powder
  • Vanilla
  • Heavy whipping cream 

How to Grate Zucchini

The first step to making chocolate brownies with zucchini is to grate the zucchini well. After washing your zucchini, cut off the stems. (Peeling is optional but not necessary.)

A food processor with a grater attachment is the easiest and fastest way to grate zucchini. Start the food processor and feed the zucchini in vertically while it’s running.

You can also grate it the old fashioned way with a big box grater: Hold the zucchini up against the grater placed over a large bowl. Run the zucchini down the side of the grater just like you would a block of cheese.

I don’t recommend using a fine microplane zester or a food processor with blades. Both will make the zucchini more pureed and watery than grated and it won’t work as well in the brownies.

Once your zucchini is grated, it’s time to bake some brownies!

How to Make Zucchini Brownies

STEP 1. Preheat oven to 350 degree F. Line a 13×9 baking dish with parchment paper. Set aside.

STEP 2. Make the brownies

In a large bowl, combine oil, sugars, and vanilla extract. Add in flour, cocoa powder, baking soda and salt. Stir together until well blended. The batter will be very dry, it’s okay!! Fold in shredded zucchini.

Depending on the moisture of your zucchini, your batter may still be slightly dry. It’s okay still. It may be moist, that’s cool too! Either way, pour the batter into the prepared baking dish.

Bake for 25-30 minutes until cooked. Remove and cool completely before frosting.

STEP 3. Make the frosting

Combine the melted butter with cocoa powder in a small bowl with a whisk. Add in powdered sugar, heavy cream and vanilla. Whisk until smooth. Spread over cooled brownies. Cut into bars and enjoy!

These Zucchini Chocolate Brownies got two thumbs up from everyone in my house. I’m so excited to have another awesome zucchini recipe to add to my list for those warm summer months when my garden is in overdrive.

Next year we’re planning on expanding our garden, but I think I will stick with ONE zucchini plant again, because clearly it loves this spot. More reason to enjoy them now!!

So here’s my question…what’s your favorite zucchini recipe? I can never have enough!

  1. These look amazing. Can’t wait to try them. Have you ever made them thicker in a 9 inch square pan? I luv thick brownies. 

  2. OMG this looked so good I had to try it and let me tell you, I am not disappointed at all! At first I was really worried because the batter was nothing but dry flour clumps, but once the zucchini was added, WOW! It smelled so nice when it was baking too. Brought some for the girls at work and got nothing but compliments and they couldn’t believe how moist it was and that you couldn’t taste the zucchini at all. If I had to rate this it would get 5/5 for taste, 5/5 for texture and 5/5 for easy.
    **it’s more cake like then brownie but absolutely delicious**

  3. Just made today and these are AMAZING! This icing might be the best chocolate icing I’ve ever made 🙂 Thanks for the fantastic recipe! It’s a winner for sure!

  4. Have you ever dozen diced zucchini for your zucchini apple crisp ?just put 3 at bags of it in the freezer . I like your recipe foe apple crisp that I am going to make today, an tomorrow the brownies.

    1. Haha! I have a zucchini Crumble recipe on the blog here: https://www.shugarysweets.com/zucchini-crumble

  5. Just took these out of the oven, they smelled soooo good I had to eat one, and I was not disappointed!  Moist, fudgey and perfect.  Love that I could put 2 cups of zucchini in them.  I added a cup of pecans, I need nuts in my brownies.  Thanks for the great recipe, it is a keeper. Now if I can just leave them to cool for the frosting………..

  6. My mind is drawing a blank this week with back-to-school and coming back from vacation.  Isn’t it nice to just make a great recipe and not stress about being creative?  These look so delicious, and I love the idea of making brownies with zucchini! 🙂 

  7. These look way fudgier than any zucchini brownies I’ve had before! I actually haven’t gotten any zucchini to bake with this year and it feels wrong – normally family and friends are dumping piles on us!

  8. Dear Aimee – these are gorgeous brownies. I could eat a plateful. I love cocoa powder in frosting. I’m a tad jealous re: your zucchini plant though. Mine is doing this year what you predict yours might next year.  Death by some horrible plant eating bug. Both plants actually. Guess it’s time for a trip to the Farmer’s Market so this black thumb can make these amazing brownies….

  9. I haven’t cooked with, baked with, or even eaten any zucchini this summer! I have no idea why…. I guess because I didn’t join a farm share this year. These brownies look INCREDIBLE!

  10. I have never baked with zucchini before but I think I better hop to it! These brownies look so delicious! Talk about delicious!

  11. I could never get sick of delicious zucchini recipes and these brownies certainly look like da bomb!  Love how fudgey and chocolately they are!  Plus I adore your substitution of brown sugar (<–YESS!)!  And that frosting?  I could eat that with a spoon!  These are a scrumptious way to use up all that extra zucchini!  LOVE IT!  Cheers!  

  12. I for one am not tired of zucchini recipes, probably because I have a ridiculous amount of them coming out of my garden daily! The brownies are a must make, although I’m pretty sure that frosting would be eaten before it made it on top of the brownies!

  13. I’m definitely not sick of zucchini recipes. Keep ‘me coming! And while you’re at it, could you send some of these brownies too, please? 😉

  14. Love how fudgy these brownies look! The perfect way to use up all of the zucchini that is available right now!

  15. Zucchini in brownies!?!?! Beyond brilliant! I’ll be over with a plate in 5 minutes =) I’ll never tire of zuke recipes and cannot wait to start my garden once we move!

  16. I definitely saw your zucchini baking shenanigans, and I LOVE IT. Keep ALL the zucchini coming! Especially when you turn them into these bad boys. I mean, there’s vegetables in there. They must be healthy right?
    Pinned!

  17. If your mind drew a blank, that is definitely rare. I remember you telling me that the baking ideas are always flowing forth!
    But hey, the baker’s block produced these brownies, so that’s amazing. They look so good!
    BTW, made a coffee granita yesterday and it reminded me of you. You’re the coffee girl!
