PIN IT NOW to save for later!

Zucchini Brownies - the easiest recipe for the most gooey, chocolaty, fudgy brownies full of zucchini! And NO ONE will guess!

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.

Zucchini Brownies

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.

Fudgy Zucchini Brownies

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.

Serving Size

Ingredients

For the brownies:

  • 2 cups all-purpose flour
  • 1/2 cup cocoa powder
  • 1 1/2 teaspoons baking soda
  • 1 teaspoon salt
  • 1/2 cup vegetable oil
  • 1 1/2 cups sugar
  • 2 teaspoons vanilla extract
  • 2 cups shredded zucchini 1 large or 2 small zucchinis
  • 3-5 tablespoons water
  • 1/2 cup chopped walnuts optional

For the frosting:

  • 3 tablespoons cocoa powder
  • 1/4 cup butter melted
  • 2 cups powdered sugar
  • 1/4 cup milk
  • tablespoon  vanilla extract
  • Pinch of salt

Instructions

  • Preheat oven to 350°F. Line a 9x13" 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.

  1. I made these per the recipe directions EXCEPT, I used zucchini that was previously shredded and frozen. Pre-freezing, the zucchini measured 4 cups. When thawed, it measured 2 cups so I went with it. I did drain the thawed zucchini before I mixed it in. I did not have to add any additional water. I did not add the frosting and opted for sprinkling chocolate chips on before baking.

    They turned out a little cakey because of the moisture from my thawed zucchini. They are delicious though and I’ll make them again!

  2. I have made these more times than I can count! When my mom visits this is her request – even for her birthday dessert! They are SO GOOD. It did take some trial and error and some cakey brownies, but I figured out that we just have really watery zucchini! So if others have that same situation, just squeeze them with a towel, paper towel, something to absorb some of that water. Then you’ll get that fudgy delight!

  3. I tried this recipe a couple of weeks ago that I had to make it again because it was so delicious and my family loved it. You don’t get that heavy feeling after eating these brownies like you do with eating Normal brownies… But it is equally if not more delicious

  4. OMG, these brownies are soooo good! I love a moist brownie and have eaten half the pan myself. Need to make more as I plan to share some and freeze some for my future sweet tooth. Would not even know zucchini is in there. Used a “pulling pork” motion to mix in zucchini which this time of year the zucchini was moist enough to not need any added water. I also cut the icing recipe in half and found that was enough for me. Amazing!

  5. I’ve made these brownies all summer long, because everyone Raves about them! E
    Easy recipe to follow and I didn’t change a thing.

  6. With the frosting they were a tad too sweet for us. Will cut the frosting down to a drizzle next time. Love these are super goey yummy brownies!

  7. Absolutely delicious! Only needed to add 2T water and they turned out super fudgy. This is my new go to brownie recipe

  8. My Kids loved the Brownies, they had no idea there was zucchini in them. Very easy recipe, will make again in the future .
