Zucchini brownies are a healthier recipe for brownies, and these are the BEST zucchini brownies ever! They’re ooey, gooey, and SUPER fudgy brownies. And NO one will know they have zucchini inside!
Yes, it is another zucchini recipe. I know, you’re probably yelling at the computer chanting “No more zucchini…NO MORE ZUCCHINI…”
Think of how I feel? At one point I think I had seven ginormous ones in my crisper drawer. Unfortunately, two didn’t make it through. When you get a pile of veggies that just keeps growing…things get forgotten underneath.
Alas, only one is left. I haven’t had to buy zucchini for dinner in over a month. In another few weeks, I’ll be grumbling at the prices and wishing I wasn’t having to buy it to make these zucchini brownies again.
Because, my friends, I will be making these zucchini brownies again. They are delightfully fudgy, due in part to the chocolate frosting on top.
Have tons of zucchini? Make Zucchini Bread!
These brownies are addicting and so good. They’re gooey, fudgy, and super chocolaty…and they have zucchini in them. So they’re healthy brownies. Practically a vegetable.
I promise you though – NO ONE will guess there is zucchini in this homemade brownies recipe. They taste like the most decadent brownies ever…and it just so happens they’re a vegetable.
#You’reWelcome.
When you make the recipe you’re going to think something is strange, because there are no eggs in it. Yes, that’s right, a brownie without eggs. Also, there’s no butter in the brownies, so if you skip the frosting these are vegan brownies.
(Don’t skip the frosting. More on that later.)
The recipe calls for water as an additional binder to the zucchini. How much water you add will vary depending on your zucchini. If you have a very wet zucchini, you may not need as much water. Add a tablespoon at a time and stop adding once the mixture JUST comes together and is no longer powdery. It is a very thick dough, almost like cookie dough. This batter is not a traditional brownie batter consistency.
Just go with it.
Let’s talk about frosting. My Grandma (my mom’s mom) used to make the best vanilla frosting. It was smooth and soft and got kind of crunchy after sitting on the cake. Problem was, my Grandma never measured. So no one was really sure how she made her wonderful frosting. Then I made these brownies and I think I’ve figured out her secret: melted butter. I can’t wait to experiment more to see if I can make the frosting from my memories.
Now you pretty much know the secret to the ooey gooey chocolate frosting. It’s cocoa, melted butter, milk, salt, and vanilla. No mixer even needed, just use a whisk! Pour it over the cooled brownies and let it semi-set. This frosting stays gooey and wet with a teeny hardening on the top.
I could drink the stuff.
I call these zucchini brownies “fork brownies”, because they’re so gooey you need a fork. #worthit
I hope you enjoy these as much as I do! I apologize in advance if you end up spending to much at the grocery store because you’ve run out of zucchini in your garden. They are that good.
Zucchini Brownies
Ingredients
For the brownies:
- 2 cups (248g) all-purpose flour
- ½ cup (40g) unsweetened cocoa powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- ½ cup (118g) vegetable oil
- 1 ½ cups (300g) granulated sugar
- 2 teaspoons vanilla extract
- 2 cups shredded zucchini 1 large or 2 small zucchinis
- 3-5 tablespoons (15-75ml) water
- ½ cup chopped walnuts optional
For the frosting:
- 3 tablespoons (15g) unsweetened cocoa powder
- ¼ cup (59ml) unsalted butter melted
- 2 cups powdered sugar
- ¼ cup (59ml) milk
- 1 teaspoon vanilla extract
- Pinch of salt
Instructions
- Preheat oven to 350°F. Line a 9×13″ baking pan with foil and spray with cooking spray. Set aside.
- In a medium bowl, whisk together flour, cocoa, baking soda, and salt. Set aside.
- Using an electric mixer fitted with a paddle attachment, mix together the oil, sugar, and vanilla until well combined. Add the dry ingredients and stir. Fold in the zucchini. Let the mixture sit for a few minutes so the batter can absorb the moisture from the zucchini. Then, if your mixture is still very powdery, add up to 5 tablespoons water (start with 1 tablespoon and work up from there, stirring well after each addition). The batter will be very thick but shouldn’t be powdery. (It partially depends on how wet your zucchini is!) Add walnuts, if desired. You may need to use your hands to work the water in instead of a spoon. The dough is super thick, like cookie dough. Do not add too much water! Spread in prepared pan.
- Bake 25-30 minutes until the brownies spring back when gently touched.
- To make the frosting: Whisk butter, cocoa, salt, and powdered sugar. Whisk in milk and vanilla. Spread over cooled brownies. Cut into squares and chill to semi-set. The frosting hardens slightly on the top but stays wet and gooey underneath.
- These brownies are best stored in an airtight container and eaten within 2 days. Chill them to make them last an extra day. They’re what I call “fork” brownies because they are so gooey.
- *NOTE* People have been saying these brownies are cakey. Every time I’ve made them they turn out super fudgy like in the photos. The problem is how much water you add. It’s hard to say how much to add because every time I’ve made these I’ve added a different amount. It really does depend on your zucchini. The batter will be very thick and need help spreading in the pan. If your batter is at all liquidy or thin you’re going to get a more cakey brownie.

I have gone gluten free and I just now did not have the time to read the rest of the comments but do you know of any one that has tryed A good mix of gluten free flour for these??
I made these delicious brownies for my 2 yr. old grandson and instead of the icing I sprinkled mini chocolate chips over them with chopped walnuts and even my daughter didn’t complain about him eating them since he’s getting his “veggies”. I have shredded a ton of zucchini so he can have them all winter.
I made them yesterday and added no water They were great! My icing was a little runny but they were moist and very tasty
I spooned mine in, probably with a very light hand (I have a big scoop but I usually shake it into the measuring cup). Yes, I agree that it’s easy to accidentally pack it! I always like knowing what the recipe author intended 🙂 And maybe people pack zucchini in more or less too! Regardless, the water in the zucchini probably does make the biggest difference. I wonder if you could just add a little more flour till it’s the right texture?
And OH MY WORD these were a.maz.ing. Mine were definitely a little on the cake-y side, but with the frosting and with a scoop of vanilla ice cream it was the best cake I’ve had in years! So now I can use the same recipe for cake and brownies and just adjust how much liquid I use–HA! My daughter has to stay away from dairy and eggs and you have no idea how hard I’ve tried to find an egg-free brownie. I even ended up with charcoal pucks once. 😉 These were *divine* and I’m about to go just plant some zucchini so I can stock the freezer for the winter! Thanks again 🙂
I’m thrilled that this was easily made dairy-free and doesn’t call for an egg AND uses up zucchini! They’re in the oven right now. The batter was amazing. Can’t wait to try the baked version 😉
I was thinking, I bet one of the reasons people need different amounts of water is that everyone measures a cup of flour differently. So the people who are a little heavier-handed may need to add water; people who don’t pack the flour in might actually not have enough flour and just the zucchini might make the batter too watery. Do you spoon the flour into the measuring cup or scoop with the cup itself?
Diana, I love you. LOL The flour thing…it’s often an issue! I recommend spooning, not scooping, but scooping is okay as long as it’s not packed. I think a lot of people don’t realize you don’t pack flour, and that when they scoop, they’re actually packing it. The water is also dependent on the zucchini – some is wetter than others!
