Zucchini Recipes

Everyone is always looking for zucchini recipes during the summer months when zucchini is out of control, myself included.  Our good friends gave us a zucchini the size of a baseball bat from their garden. I am trying to come up with creative ways to use our humongous zucchini. I love making my favorite zucchini breads, chocolate and lemon, but I wanted to try something new. Last night, we needed a dessert to take to a party, so I made chocolate chip zucchini brownies. Yes, dessert is always needed, especially when zucchini brownies are involved. They are SO good and one of my favorite summer desserts.

Magic Zucchini Brownies

I love baking with zucchini. You start with a green vegetable and end with a decadent dessert. I kind of feel like a magician because people are always so surprised when they find out zucchini is involved. Zucchini really is a magic ingredient. Zucchini makes these brownies extra special.

When I pull a warm pan of brownies out of the oven everyone always gathers around for a taste because they don’t look like zucchini brownies, they look like a pan of fudgy, chocolaty brownies! Everyone lines up for a taste! They are always blown away because these brownies are perfection! They are so rich and delicious!

A few tips for making zucchini brownies:

  • You can use a large or small zucchini, the size doesn’t matter. I know a lot of people like to use overgrown zucchini for baking and that is just fine. Don’t let those big zucchini go to waste.
  • Shred the zucchini with a cheese grater or food processor. I never peel the zucchini.
  • I don’t squeeze out the moisture in the zucchini for this recipe. You want the brownies to be moist. If your zucchini is extra watery, you can squeeze it out a little in a paper towel, but don’t get rid of all of the moisture.
  • The mixture will look dry when you start and that is ok. It will be just fine after you add in the zucchini. Just be patient:)
  • Stir in 1 cup of the chocolate chips into the batter and save ¼ cup for sprinkling on top. The chocolate chips make the brownies even more chocolaty, which is a very good thing!
  • This recipe makes a 9×13-inch pan, which makes this brownie recipe a great one to share!
  • Pro tip-cut the brownies with a plastic knife after they have cooled. A plastic knife is magic and doesn’t make a lot of crumbs.

If you are still looking for ways to use up your garden zucchini, give these chocolate chip zucchini brownies a try! They are a favorite at our house!

  • 1 1/2 cups granulated sugar
  • 1/2 cup canola oil or vegetable oil
  • 2 cups all-purpose flour
  • 1/4 cup unsweetened cocoa
  • 2 cups shredded zucchini don't squeeze out the moisture
  • 2 teaspoons vanilla extract
  • 1 teaspoon salt
  • 1 1/2 teaspoons baking soda
  • 1 1/4 cups semi-sweet chocolate chips divided


  • Preheat oven to 350 degrees F. Grease an 9x13 baking pan with cooking spray, set aside.
  • In a stand mixer, combine sugar, oil, and flour, combine until mixture resembles wet sand. It will be dry looking and that is ok. While mixing, on low, add cocoa, shredded zucchini, vanilla extract, salt and baking soda. Mix until well combined. The mixture will moisten once the zucchini is added. Stir in one cup of the chocolate chips.
  • Pour brownie batter into prepared pan and sprinkle with remaining chocolate chips. Bake for 28-32 minutes or until a toothpick comes out clean and the brownies are set.
  • Cool completely on a wire rack. Cut brownies into squares and serve.

    These are incredible! I’ve made them twice now, and probably making them again this weekend. So fudgy, chocolatey, and you can’t even tell there’s a veggie in there! I do have to bake them about 5-10 minutes longer than the directions say, but that’s about how long normal brownies take anyway.

    These brownies are EVERYTHING! They earn rave reviews from everyone who tries them 🙂

    I do substitute half an avocado for half the oil and add 1/2 cup of chopped walnuts (and adjust for high altitude–9000 feet above sea level), but the recipe is wonderful as written!


  3. These are AMAZING!!!!! Kind of cake-ish, but definitely a brownie. I made for a picnic, and received SO many compliments.

  4. 5 stars
    These brownies quickly became my favorite this summer! So simple to make but seriously delicious and not too heavy! I already shared the recipe with my mom and best friend, both of which made it with good results!

    This recipe is the best ever brownie recipe!! AND it’s Vegan!!! (if you use vegan chocolate chips). My whole family loves this zucchini brownie recipe. We’ve made it dozens of times! And a great alternative to brownies for people who are vegan!

    This was so good! I definitely recommend this recipe to anyone interested in investigating zucchini in baked goods. I have to say my batter came out a bit dry. I ended up adding 1 and a bit tablespoons of water and some more oil (I used olive) but apart from that it was delicious.

    First time baking with zucchini, and definitely not the last time! These turned out so moist and delicious! Definitely going to give the other zucchini recipes a try!

      These moist chocolatey brownies are delicious and hide the zucchini perfectly—couldn’t tell it was an ingredient. I made them with dark chocolate chips and topped with a dollop of whipped cream. Loved these brownies, however, with or without the whipped cream.

    I couldn’t believe how well these turned out. From wet sand to something that came together so well and so fudgey! Thanks for making my mother’s day!

  9. Recipe was great; Easy to understand and assemble. Needed to increase cook time a bit. Brownies tasted delicious, a keeper!

  10. These are delicious. I added some fresh figs,replaced half of the oil with raspberry applesauce and reduced sugar by 1/4cup and they were great.

  12. I’ve made this a number of times and always use 3 cups of shred zucchini and just 1 1/4 cup sugar. I call it cake, and everyone always loves it. This is a very, very good recipe. Thanks for helping me to figure out what to do with all the summer squash (I don’t just use green zucchini, I also use yellow summer squash or patty-pan if that’s what I have on hand. And the plastic knife tip is a winner.

    Was looking for a quick dessert earlier this week and I was out of butter and eggs, but had plenty of zucchini! My zucchini didn’t have much moisture so the batter was looking a little dry, so I added about 1 tablespoon of water & it worked like a charm, they turned out so delicious I came back to make them again today!

    By far, the best brownie recipe I’ve found. I’ve shared these brownies with a few lucky folks and they always want the recipe because they’re that good. Easy to make and delicious – what more could you want?

    Flavor was wonderful. Very tasty. HOWEVER, I could not cut into squares. We ended up w/ Chocolate Zucchini ‘Crumble’ Brownies. I had to leave it in the oven 5 min longer. Still didn’t hold together. : (
    Will have to figure out what to do to make these work!?!

    This has been my go-to recipe since being inundated with LOTS and LOTS of zucchini. We love this! I had followed it “exactly” as well as made a couple of changes now. *(I add 1/4+ cup of ground flax-seed. No one notices and it’s a great & easy add-in. I also sub 1/2 the sugar with SWERVE and that is also not noticed. Reduced overall sugar to 1 & 1/4 cup.)
    Shared the recipe w/ several others. Everyone likes it!

    These are some of the best brownies I have made from scratch! Not gonna lie, I made them at first just to use up a zucchini–but I would definitely go out of my way to make these again!

    I absolutely LOVE these brownies. I make them at least once a month. I have made a few changes:
    1. I do remove a lot of the water from the zucchini. Otherwise it’s really difficult to get the middle to bake without overbaking the outside.
    2. I have begun using coconut sugar instead of granulated sugar (1:1 ration if measuring by volume).

    I think I’m going to add in some fresh mint the next time I make these, just to try out the flavor.

    Thank you for this recipe. It really is a favorite in our household and always cures my chocolate cravings!
