Gluten Free Zucchini Brownies

Zucchini Brownies are one of our treats. When I started a Gluten Free diet it was in the middle of harvest season and we had zucchini coming out of our ears. Determined to turn my favorite treat into a gluten free snack I came up with this recipe. First, you would never know these are gluten free! And second, you can't even tell these are filled with a healthy veggie. Plus the gluten free version contains whole grains so it's twice as healthy!

Gluten Free Zucchini Brownies

  • 1 1/2 c. sugar
  • 1/2 c. oil
  • 2 t. vanilla
  • 2 c. shredded zucchini
  • 1. c. brown rice flour
  • 1 c. sweet rice flour (or sticky rice flour)
  • 1 1/2 t. baking soda
  • 1 t. salt
  • 1/3 c. cocoa

Mix all together well and pour into a 9x13 greased pan. Bake for 35 mins at 350F or until a toothpick comes out clean. Once cooled you can make the frosting:


  • 6 T. butter
  • 6 T. milk
  • 1 1/2 c. sugar
  • 1/2 c. chocolate chips

On the stovetop, mix together the butter, milk, and sugar. Heat together until the mixture boils. Boil for 1 minute. Remove from heat and stir in the chocolate chips. Pour over the brownies and let it cool before you cut.

This recipe works great with both fresh zucchini and frozen shredded zucchini. Remember that if you are using frozen zucchini you may need to drain it first otherwise your brownies will end up too soupy from the extra water content.

Thanks for these! What is the reason for using sticky rice flour, and can I substitute it with other flours and xanthan gum? I’ve been looking for sugar-free/ gluten-free/ vegan baking recipes!! ๐Ÿ™‚


10 Merissa January 31, 2013 at 10:51 am

You could try it but yes you’d need to add some xanthan gum. I just like using it because it’s cheap and in my gf flour blend that I make:)

Hi! We LOVE these brownies… & the frosting is FABULOUS!! I assumed the brown rice flour was supposed to be 1 cup, but wanted to check w/you about it??

LOVE, LOVE, LOVE your blog… lots of great things!!


12 Merissa March 9, 2013 at 2:37 pm

Yes, 1 cup ๐Ÿ™‚

I would like to try this recipe – it looks awesome! I’ve never baked with cocoa before. What do I look for in the grocery store?


14 Merissa July 14, 2013 at 2:11 pm

Just make sure to look for Unsweetened Cocoa Powder. You should be able to find it with all the regular baking supplies. ๐Ÿ™‚

I made these and they turned out great! They taste just like your picture looks; super fudgy and delicious. I couldn’t find sticky rice flour so I used white rice flour instead with great results. Thanks for the recipe!!

These look amazing, can’t wait to try them! :o) Thanks, Charlie.


17 Charlotte July 27, 2014 at 7:35 pm

These look amazing! Can you recommend what I could substitute for the butter in the frosting?


18 Merissa July 27, 2014 at 8:42 pm

Hmmm, I’m not sure, I haven’t tried anything different for the frosting. You might be able to use coconut oil but it won’t set up quite the same or have quite the same flavor.

We used cane sugar, Namaste Foods “perfect flour blend”, and carob chips….. Just put it in the oven so we will see ……


20 Merissa August 25, 2014 at 7:18 pm

I hope it was good!


21 Krishna November 6, 2014 at 8:23 pm

Does this brownie need the frosting? I was thinking of doing without it. We are vegan as well. Thank you.


22 Merissa November 7, 2014 at 7:49 am

It’s good either way ๐Ÿ™‚

Hi – I came across this recipe on Pinterest and can’t wait to try it given that we’re experiencing an early bumper crop this year (it’s only late June and we’ve already harvested 15 lbs =:-s of the lovely things). I do have a question though, is it correct that this recipe contains no eggs? I made it to recipe and it’s in the oven as I type. I have my fingers crossed that no egg was correct ๐Ÿ™‚



24 Merissa June 28, 2015 at 7:51 am

That is correct ๐Ÿ™‚

I’ve made these a few times and are my go-to recipe when brownies are in need… I found tonight that mixing the batter in the food processor was significantly better than mixing by hand… I will continue to do this from now on and recommend this to others… Thanks for the great and SIMPLE recipe!
