Zucchini Brownies

5 from 25 votes

These ultra rich and fudgy dark chocolate zucchini brownies taste so much like regular chocolate brownies that you’d absolutely never guess there’s an entire cup of zucchini packed into the recipe!

Zucchini Brownies Recipe

If you’ve never tried making zucchini brownies, they are a must try.

The zucchini allows you to add moisture and softness without all the extra fat, cutting back on the oil and calories while secretly packing the brownies with nutrition at the same time.

Brownies that are healthy and don’t taste healthy?? It’s the BEST of both worlds!

The brownies go really well with almond milk or with this Whipped Coffee Recipe.

Healthy Zucchini Brownie Batter

Vegan zucchini brownie ingredients

The recipe is made up of traditional brownie ingredients, including cocoa powder, flour, sugar, and optional mini chocolate chips.

Vitamin packed zucchini stands in for much of the oil, adding extra moisture and nutrition without all the fat and calories. Or make them oil free by using almond butter.

If you prefer sugar free brownies with almond flour, try the keto brownies listed below.

These can be plain or frosted with Chocolate Cream Cheese Frosting.

How to make zucchini brownies

Start by gathering the brownie ingredients and shredding the zucchini (see below).

Preheat the oven to 350 F. Line an 8×8 pan with parchment paper, or grease the bottom and sides of the pan. Set aside.

Combine the dry ingredients in a large mixing bowl, and stir very well. Add wet ingredients, including the zucchini, and stir to form a batter.

Smooth the brownie batter into the prepared pan, and bake on the oven’s center rack. For ultra fudgy brownies, my favorite trick is to remove the underdone brownies after 15 minutes, let them cool, then refrigerate overnight so they firm up without being overcooked or cakey. If you’re in a rush or do prefer cake-like brownies instead of fudge-like ones, bake for 20 minutes or until fully cooked.

The brownies (like many baked goods) are much sweeter and richer the next day, with a better brownie texture. So let them sit a day before serving… if you can wait!

How to shred zucchini:

The recipe calls for one cup of zucchini, which is about one or two zucchini, depending on the size. I usually buy three just to be on the safe side, and because leftovers can always be used up in this Coconut Curry Recipe.

The easiest way to shred a zucchini is not with a grater, but with a food processor. Chop the vegetable into medium pieces, then pulse until finely grated, stopping a few times to scrape down the sides of the machine if needed.

Measure out the one cup after processing, not before. While some recipes tell you to do so, I didn’t bother to blot out excess moisture here.

    Oh. My. Gosh. I have been looking ALL DAY for a healthy zucchini brownie recipe. What a freaking coincidence. This looks the BEST out of all of them. I was going to try your other coconut flour brownie recipe, but I think I’ll give this one a try first. Two dumb questions: Can I sub date paste/bananas/fruit source for the sugar? I have no sweet tooth and would like to keep it that way by not using added sweeteners, zero calorie or not. Also, are these fudgy with a shiny crinkle top or cakey? Most fudge brownies call for less flour and more fat, these are the opposite. Again,I am just so stoked that you HAPPENED to post this today! Will be trying no matter what. I’ve never had a recipe fail from your site yet:)

    • CCK Media Team says

      Hi! Sorry we really don’t know how subbing anything for the sugar will change the taste/texture so can’t say. The brownies are more cakey, whereas Katie’s vegan brownies or keto brownies are more fudgy. The 5 ingredient brownies are also more fudgy. Be sure to report back if you try them!

    • Sandra says

      Holly, I look for healthy recipes, too, and this is not a healthy recipe. Flour and sugar are UNhealthy ingredients, and so is oil if you use that option, and most chocolate chips have sugar. So, go elsewhere for healthy. I bet they taste good, though.

      • Michelle says

        It’s a dessert site, Sandra. Why are you seeking out a dessert site if you are avoiding sugar (even unrefined, which Katie said can be used here)? Literally the blog title says Chocolate so I’m betting you knew you’d find chocolate recipes on here. There’s also nothing wrong with whole grain flour. Health is subjective and you can avoid flour if you wish (Katie has a Keto brownie recipe too) but that doesn’t mean everyone on here finds it unhealthy too. I am here because I try to eat high fiber, lots of vegetables, low calorie, and enjoy some lower sugar desserts that still do use sugar because I think that’s healthier than fake sugar substitutes. This zucchini brownie recipe checks all those boxes for me.

        • Sandra says

          Once in a while, she will have a dessert recipe that is somewhat healthy, and at least healthiER than some others. She also has recipes that are not desserts–as you point out–so I suppose I’m here for the same reasons you are, then, for the recipes that are not desserts and for finding a few that might actually be healthy. So why your question about ME being here? As if I shouldn’t be. Anyhow, I was replying to Holly, who said she was seeking a healthy brownie recipe, and I was letting her know that this one is not healthy.

          • Hannah says

            I am pretty sure no one needs you to point out to them that sugar isn’t healthy and that chocolate has sugar. It sounds like you just want to troll other readers and give input where no one asked.

          • Lily says

            Sandra, isn’t a “healthy brownie” an oxymoron? Brownies are always going to be “unhealthy”, though these are a great deal less unhealthy than a traditional brownie. A traditional brownie is at least 3 times as calorie dense, therefore I would definitely consider these a healthy option in comparison. It’s a sweet for goodness sake! They’re to be eaten in moderation. Loosen up a bit. I think your obsession with foods being as healthy as possible is more unhealthy, there’s absolutely nothing wrong with treating yourself every now and then.

            These brownies are fab. I’ve made several batches now, my friends and family are very grateful. They’re so quick and easy to make, foolproof. I’ve been baking them for the full 20 mins and they are a bit delicate, I’ll give the fudgy option a go!

          • Lily says

            I forgot to mention, I’ve also been adding a couple of teaspoons of instant coffee to the mix- though this isn’t for everyone!

    Making these today! They look UNREAL and fudgy and just what I was looking for and didn’t even know it. I’ve never had a zucchini brownie but am so excited to try them!

    • Sandra says

      Sorry to disappoint you, Hannah, but I am not a troll. I do not do that. I give my honest opinion sometimes in comments, just like you do. But some people can’t handle other people’s opinions, and if not in agreement with theirs, unjustifiably accuse them of being a troll. As for giving input where no one asked, that’s what a comment section is for. And no one asked you to give input on my comment that was to someone else, not you, but you butted in, so perhaps you are the troll here? And you know what, some people really do need to know that sugar isn’t healthy.

      • Hannah says

        Maybe if you allowed more chocolate and brownies into your life, you would be a happier person and not try to bring others down. I won’t reply again or even check back to see if you reply again, because I don’t think it’s nice to turn the comment section here so negative. I do wish you well, genuinely.

        • Sandra says

          If you don’t think it’s nice to turn the comment section into something negative, then why did you do it? I made a reply, to someone else, not you, that the recipe is not healthy. For some unknown reason, that bothered you and you felt the need to butt in. Why? And saying a recipe is not healthy is not bringing anyone down, so don’t be trying to read something into a comment that is just not there. People should be able to leave comments without others feeling the need to jump in and jump on them and make accusations if they have a different opinion. Perhaps you would be a happier person if you would quit letting other people’s comments bother you so much.

            I’m going to eat three zucchini brownies in Sandra’s place. They look amazing Katie! Absolutely the best email I got all day 🙂

    YES I AM SO HAPPY TO SEE THESE! I have three zucchini on my counter right now and I know just what I will do with them 🙂

    • CCK Media Team says

      Thank you so much for the suggestion. We are going to do this from now on, putting a link to the blog post right above the ingredients in the email. (We’ll also look to see if we can figure out how to add the print button right to the email.)

    Today I’m checking out your zucchini brownies. Awesome, can’t wait to try, what with zucchinis abounding in the garden currently!! I asked for the the photo to print out on the recipe because they look so darned delectable… but the photo doesn’t print. So sad.

    • CCK Media Team says

      Hi! We hope you like them! Sorry we are not sure how to include something like that. I think Katie chose not to have it in order to save ink for readers.

  5. Sarah says

    A friend gave me an overgrown zucchini from her garden and these were the first things I made! Delicious. What are thoughts on making these in muffin tins and freezing? I’m thinking maybe ~12min baking time, but not sure how they’d do on a thaw and reheat (i.e. would the zucchini make them mushy)?
