These Zucchini Brownies are gluten free, dairy free, and low sugar. You would never guess that they have a hidden vegetable because they’re so rich, decadent, gooey, and with crisp edges. Everything you want in a brownie, all made with simple, nutritious ingredients!
To this day, one of my most popular recipes is for my Double Chocolate Zucchini Muffins! I meal prep these a lot because they’re a great balanced snack that tastes like a treat and they’re filled with tons of nutrients from the hidden zucchini and other ingredients. You really can’t go wrong with hiding vegetables in baked goods, especially when there’s chocolate involved so I got to work on these zucchini brownies and let me tell you, I was SHOCKED at how good they were when I first tried them!
Because everything is blended together, the zucchini is completely masked by the other ingredients but it adds to the thick consistency of the batter. These brownies have crisp edges, thick, and fudgey centers. Each bite melts in your mouth and that’s everything I want in a brownie 🙌
These are a great balanced snack or treat for any time of day. There’s fiber from the zucchini and oats, carbs from the coconut sugar and oats, healthy fats from the egg and coconut oil, and the egg adds some protein too! Make a batch to meal prep for the week so you have a treat on hand, bake for a gals night, or as a healthier treat for your kids lunches.
Why You’ll Love These
- THE perfect brownie texture – The key is to let these cool in the pan for a bit before taking them out and cutting. They continue to bake a little in the warm pan which helps firm them up and give those crispy edges!
- Low sugar – These are sweetened with coconut sugar which is a great option for a less refined, lower glycemic sweetener. You can also use monk fruit if you want to keep things completely sugar free.
- Picky eater approved – If you want a way to sneak veggies into a picky eaters diet… baking them in treats is the way to go! The zucchini is blended so smoothly with the rest of the batter, you would never guess it’s in there.
- Dietary friendly – These are gluten free, dairy free, low in sugar, and can be refined sugar free depending on what chocolate you use if you’re adding that on top.
What You’ll Need
- Zucchini
- Oats – My favorite oats are One Degree Gluten Free Sprouted Oats because they’re organic, glyphosate free, and sprouted for easier digestion.
- Egg
- Unsweetened cocoa powder – You can also use cacao powder but it might be a little bitter, just add a little more sweetener!
- Granulated sweetener – I used coconut sugar because it’s less refined and lower glycemic (aka not as much of a blood sugar spike). You can also use monkfruit sweetener if you want this to be completely sugar free.
- Coconut oil – Any neutral oil will work, I prefer coconut oil when baking.
- Chocolate chips – These are optional, but you can never have too much chocolate right?? You can use any size chocolate chips or even chop up a chocolate bar.
How To Make
- Preheat the oven to 350F and line a loaf pan with parchment paper. (Tip: Cut a piece of parchment paper that fits the width of the pan and leaves overhand on two sides. When you’re done baking, you can easily lift the brownies from the pan and don’t have to worry about them sticking!)
- Add all ingredients to the cup of a high-speed blender and blend until smooth. You might need to stop and scrape the sides, blend again a couple of times! The batter will be thick, similar to regular brownie batter.
- Pour the batter into the loaf pan and smooth the top to make sure it bakes evenly. (Tip: Before baking, add chocolate chips on top for added texture and chocolate!)
- Bake for 30 minutes until firm. Once done, take out of the oven and top with flakey sea salt to help bring out the chocolate flavor.
- Let them cool in the pan for a few minutes before lifting the parchment paper from the pan and slicing into six pieces. Enjoy!
Recommended Tools
- High-speed blender
- Parchment paper
- Loaf pan – I use a standard one pound loaf pan.
- Silicone spatula – for thicker batters like this, it’s easier to get out of the cup and smooth in the pan!
- Stainless steel measuring cups and spoons

Would this work with one cup of almond flour?
I was wondering if maple syrup sugar (simply granulated maple syrup and nothing added) would work in this recipe. I think Maple might be more sweet so maybe I’d have to decrease the amount…? Do you think it would be good in this recipe?
Hi Julie! Maple sugar would work in this recipe since it’s an easy swap for another granulated sugar. The hint of maple sounds delicious 🤩
I have made this recipe several times and put them in 4 small ramekins. I also use monk fruit sweetner. They are the best!
Ooooh I love this idea to make single-servings of them! I’m going to have to try this next time, thanks Marsha!
These ended up being incredibly wet and liquid after over an hour in the oven. Taste was great, but texture was not, would try again but draining the zucchini before adding additional ingredients.
Hi Dakota! Sorry to hear these didn’t turn out well your first try. Draining the liquid from the zucchini is a great idea in any baking recipe because they hold so much water. I recommend shredding the zucchini, placing it between paper towels, and pressing until most liquid comes out. I hope that helps with your next bake!
Is it possible that you add a weight for the Zucchini? Their size varies quite strongly regional-wise.
Hi! One medium zucchini is about 180 grams which is perfect for this recipe. I hope this helps!
I just made these and loved them! I used coconut sugar and chocolate and peanut butter chips. Yum!
Hi Pamela! I’m so glad you loved these and added your own twist 🙌 I’m going to have to try adding peanut butter chips next time, sounds amazing!
This was delicious. Even my 10yr old granddaughter loved these “brownies.” I never even told her about the zucchini!
That’s the best when you can sneak veggies in and nobody would ever know 💁♀️ So happy she liked them too!
I made these brownies and everyone loved them! Used my food processor- super easy!
Yay! Glad you love these as much as I do!
