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!

  • 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.

    I was looking for a recipe to use up my massive harvest of zucchini and ended up on this one. These are absolutely amazing! I peeled the zucchini and shredded it really fine, used about a cup and a half of it since it was so fine. They turned out delightful. Served with some vanilla icecream. My 3 year old and anti-veggie friend both loved them!!

    Well to be honest my child’s hate any treat with zucchini in it ( mine usually go to the pigs) but this year I decided to grow patty pan squash. I wanted to do something sweet with it instead of savoury and I stumbled across this recipe. Because patty pan is way less wet than zucchini I had to add a little water to give it the right consistency for pouring. The bake time was right on and I seriously whipped these up at 10:30pm so that my daughter and I would have a nice treat to go with our work lunches. My youngest said they were the best brownies she has ever had! The only thing I might try next time is some walnut incorporated into batter. So perfect and I will make again. Just curious if it freezes well! Thank you so much!

  3. Made those! Added an egg and 1/4 c milk because of dryness! Unbelievable! Cut into larger pieces, topped with whip as a dessert. Awesome to freeze

    Recipe is good depending on what you’re looking for. I love a dense, chewy brownie, and this is definitely more cakey than anything else, which is great if you love that, but not if you don’t. They taste nice, can’t even tell the veggie is in there. Next time I might try significantly lowering or leaving out the leavening agent and see what happens 🙂

    This is good, but not what i was expecting. This is cake. Not brownies. Not rich or fudgy. It’s a light cake. Needs more cocoa powder and a couple eggs.

    These are AMAZING! I think I would grate the Zucchini on one size smaller on the grater – but I couldn’t believe how moist and delicious it turned out!

    I have enough Zucchini left for another batch, and this one I will make with the Black Cocoa (that you used for your Oreo’s) for a friend who LOVES dark chocolate – I bet they turn out awesome as well!

    1. OOPS…the Oreo recipe was from Acre Homestead – who featured your recipe!!! (you can find Becky on YouTube if you are interested!)

    These are excellent and everyone I share them with loves them. The only thing tho is they take longer to bake than the recipe states. It’s not my oven, I checked that. I will definitely be making these for years to come.

  8. I’ve never left a comment on a recipe before until now. These brownies were the best brownies I’ve ever tasted in my life! Cake, brownie-what ever you want to call it. Absolutley delicious! Thanks for this recipe.

    These are amazing! I read one review that suggested adding one egg and 1/4 cup milk, I followed that rec and boom So YUMMY!
    I did put mine in a 7× 11 pan,they needed a good 45 minutes to bake, center was a tad googy but still tasty.

    Will def add this to my collection of go to dessert recipes.

    I love this recipe! Since there is only my husband and myself, I cut the recipe in half and I add 1 egg to the batter. It’s great that way. If I were to make the whole recipe I would add 2 eggs. That’s just me. . .

  12. I am so glad you shared this recipe. I made it yesterday. My family loved them! So delicious, best brownies I have tasted. Followed your recipe and they came looking just like the photo you posted. Thank you.

    I don’t normally comment on recipes but this one is one to beat! I added 1 egg and 1/4 cup of milk as recommended by the comments for a more dense moist texture. Great for beginners as well- didn’t have a mixer so I used my hands and a spatula to combine the ingredients. Turned out awesome! Will definitely be making again!

  14. These are delicious! I used 1 cup instead of 1-1/2 cups of sugar and it was plenty sweet. I also added an egg. Thank you Maria for sharing your yummy recipe.

    I’ve made these approx 100 times over the past few years. I love telling people about them, seeing the look of skepticism in their faces upon hearing they have zucchini in them, and then seeing the look of confusion and delight on their faces when they take a bite.

    A+ recipe!

    These are the best Brownies of any kind! I don’t even tell people about the zucchini to give them an opportunity to say they taste it. One tip that I do have is to squeeze the zucchini and save the juice. If the batter seems too dry, add some of it until desired consistency. I find that some zucchini are watery and the batter can be too thin. I LOVE ❤️ THIS RECIPE.!

    Perfect. Added 1 cup chopped walnuts. So good. More cake like than my regular ones but super tasty. It’s a keeper.

    These brownies are delicious! Not only do they taste normal, but you can’t even see the zucchini, if you have picky little ones.
    In some reviews, I read that the brownies were cakey, so I did like suggested and reduced the baking soda to 1 tsp. They turned out great! They definitely are lighter and less dense than most brownies, so if you like chewy brownies, maybe reduce the baking soda even more to 3/4 tsp or 1/2 tsp.

    This is an easy and delicious recipe! I was skeptical at first when I first saw the consistency of the batter! It looked dry, it moistened up when the zucchini was added but very thick. I wasn’t sure this was going to come out looking like the photos!! I was wrong! These are moist and delicious!! No need for adding anything else! I’m glad I trusted the recipe as is! Enjoy!

    Really good. Replaced the oil with unsweetened applesauce. Worked out great. Gooey. We heated it up and put vanilla ice cream on top. It was almost like a lava cake!

    Thank you for the zucchini brownie recipe. It was delicious and my family and friends loved them! My family loves nuts in brownies so I put 2 cups of walnuts in it! Big hit!!!
    Can’t wait to try more of your wonderful recipes!

  22. I have been making these for at least a decade. Everyone always loves them and can’t believe they are vegan (I use vegan ingredients). 😉
    Thank you for a great amazing recipe that quickly became a family favorite! <3

  23. These brownies are delicious and sooo beautifully moist (even the edges)!!
    I reduced the sugar by one third and didn’t have enough chocolate chips for the mixture so just sprinkled a handful on top and it still came out great. The kids keep coming back for more! Simple, easy recipe, especially with my thermomix to do the grating and mixing. As a busy mum of six I’ll definitely be coming back to this recipe when I have excess zucchini! Thankyou for sharing it

    These are SO great! I make them often as they take almost no time to put together and it is a great way to use up an abundance of zucchini from the garden. I made these not long ago for a group of young adults in their 20s and four of the six of them asked for the recipe. Delicious and not dry. The perfect brownie.
