Összetevők és helyettesítések
Let’s see what you need to make these fudgy brownies.

- Reszelt cukkini – Grate and drain the zucchini. Baking with grated zucchini requires discarding all the zucchini water, or your brownies will be too wet. Read the paragraph below about how to drain water from grated zucchini perfectly.
- Juharszirup – Use maple syrup or any unrefined liquid sweetener like coconut nectar, agave syrup, or brown rice syrup. Sugar-free maple-flavored syrup also works for this recipe.
- Kókuszdió or unrefined cane sugar. You can use any crystal sugar or sweetener you like. So if you want a sugar-free alternative, use erythritol or allulose.
- Mandulaliszt – Use ultra-fine mandulaliszt for best results. Almond meal is coarse, and it won’t absorb the moisture as well in the recipe. Also, if you like, you can use gluten-free oat flour can be used as a replacement for almond flour, but the brownies will be slightly drier.
- Mogyoróvaj – Use a fresh, runny jar of mogyoróvaj with no added sugar and oil on top. Using an old jar of peanut butter where the nut butter has dried out will result in a dry, less fudgy brownie. You can also use fresh runny almond butter or tahini for a paleo-vegan brownie recipe.
- Kakaópor – I prefer using édesítetlen kakaópor.
- Kókuszolaj – you can use refined or unrefined kókuszolaj.
- Flax Egg – A flax egg is a natural vegan egg made of water and a flaxseed meal. It allows the brownie batter to hold well without using eggs from animal sources. It’s quite easy to make a flax egg. Bring one tablespoon of flaxseed meal, brown or golden, into a bowl and whisk with 3 tablespoons of hot water. Set aside for 15 minutes until it forms a gooey egg-like texture. Use it as an egg in your zucchini brownie recipe.
- Vaníliakivonat – to add flavors.
- Só – to enhance the flavors of the chocolate.
- Baking Soda – or use double the baking powder if preferred. This makes the texture a tad airier.
How To Make Vegan Zucchini Brownies
It’s an easy vegan zucchini brownie recipe made in 1 bowl. However, there’s one important trick to make the best zucchini brownie recipe. The water content in zucchini is so high that if you don’t drain your grated zucchini of their liquid, the brownies won’t hold. It sounds easy, but it can be challenging to squeeze out all the zucchini water by hand.
- First, I recommend choosing a clean towel. Any tea towel will do. Then, place the grated zucchini into the center of the towel and gather the corners of the towel.

- Twist the towel to squeeze the grated zucchini into a ball, and keep twisting as hard as you can until no more zucchini water comes out.

- Finally, measure the grated zucchini required by the recipe. Note that for 1 cup of grated zucchini, you should get around 1/4 cup of water that you can discard or use later for a smoothie or to flavor a curry. Transfer it to a large mixing bowl.
- Prepare the flax egg in another bowl by combining the flaxmeal (1 tablespoon) with water (3 tablespoons) in a bowl. Set it aside for 15 minutes until it forms a sticky, gooey texture resembling an egg.
- Preheat the oven to 350°F (180°C). You can either line a 9-inch x 5-inch baking tray with parchment paper or a 9-inch x 9-inch square brownie pan. Read my tips below for the baking time because it won’t cook as fast.

- In the large mixing bowl with grated zucchini, add the runny peanut butter, flax egg, vanilla, maple syrup, and coconut sugar.

- Combine the ingredients until the batter is consistent, liquid and shiny.

- Pour the cocoa powder, baking soda, salt, and melted coconut oil (not hot, just liquid). Stir until the cocoa powder is well integrated into the other ingredients.

- Add the almond flour and stir until it becomes thick and difficult to combine.

- Transfer the vegan zucchini brownie batter to the prepared pan of your choice.

- Bake the brownies for 30 minutes at 350°F (180°C) until the top and sides start to crackles and a toothpick or skewer inserted in the center comes out clean of crumbs or with just a few. Adjust the baking time to the side of the pan with my tips below.
- Like with all brownie recipes, it is crucial to cool down brownies in two steps. First in the pan and then on a cooling rack. The first step takes 10 to 12 minutes. The second step takes 30 minutes at least. This 2-step cooling process allows the brownie texture to form gently, getting firm and crispy outside and moist inside.
Tips for Perfect Brownies
- Friss mogyoróvaj – Whether you choose to use peanut butter, almond butter, or sunflower seed butter in this recipe, the key to success is to use a fresh jar. In fact, old peanut butter gets dry and hard. As a result, it creates dry and crumbly brownies. That is why I recommend using a freshly opened jar with that little layer of oil on top. Stir the jar to combine the oil with the peanut butter and then measure. Also, make sure you are using peanut butter with no added sugar and no added oil. These two potential additives in peanut butter also impact the taste and texture of your zucchini brownies.
- Sütési idő – The brownie’s baking time depends significantly on the baking dish’s size. The 30 minutes recommended in this recipe is for a 9-inch x 6-inch brownie pan. If you are using a larger pan, your brownie will be thinner and bake faster. If the pan is smaller, your brownie will be thicker and require more baking to set.
- Cool Brownies – My trick is to pop the lukewarm brownie in the fridge for 10 minutes to give it an extra fudgy texture. If you love super fudgy brownies, then try this! You will be impressed by the result!

Yes, you can absolutely freeze these chocolate zucchini brownies as long as you freeze them individually.
First, make sure the brownies are at room temperature, at least out of the oven for 3 hours or overnight. Then cut the brownie into bars. A good serving is 16 bars for this recipe.
Finally, freeze each portion in an airtight box, leaving 1 thumb of space between each.
Don’t overlap or stick the brownie bars together, or they will be difficult to defrost individually.
You can defrost them on a plate on the counter at room temperature 3 hours before serving. You can also rewarm the frozen brownie for 2-3 minutes in the oven at 215°F (100°C).
No, you don’t feel the zucchini at all in this recipe. You won’t feel the zucchini flavor or the zucchini texture.
So now, you might be wondering why you should add zucchini to a brownie mix?
Zucchini are adding moisture and create an ultra-fudgy texture in brownie recipes.
The purpose of adding zucchini into a brownie mix is not only to sneak vegetables into your desserts but, first and foremost, to create the fudgiest, moist chocolate brownie on earth!
This happens if you didn’t squeeze out all the water from the grated zucchini. To fix that, add 1 or 2 extra tablespoons of almond four or oat flour to the batter. Remember that the batter must be thick and sticky, not runny or liquid.
This can happen because there are:
– Too much water left from the zucchini in the batter.
– A too-short baking time.
– Not enough cooling down.
To fix that, place the brownies for 10 minutes in the freezer!
The quick burst of cold on the lukewarm brownie will set the brownie batter and fix your problem.
Remove from the freezer after 10 minutes, slice, and store in the fridge or at room temperature.

Vegán cukkini brownie
Hozzávalók
Flax egg
- 1 evőkanál Lenmag liszt - + 3 tablespoons lukewarm water
Manó
- 1 csésze Cukkini - finely grated, drained from their juice in a clean towel, (about 2 large zucchini, skin on, end trimmed)
- ½ csésze Mogyoróvaj (sózatlan) - runny, no added sugar
- 1 teáskanál Vanília
- ¼ csésze Juharszirup - or agave syrup or rice syrup
- ½ csésze Kókuszdió - or unrefined cane sugar of choice

- ½ csésze Mandulaliszt - see note for options
- ½ teáskanál Szódabikarbóna
- ½ teáskanál Só
- 2 evőkanál Kókuszolaj
Utasítás
- Preheat the oven to 350°F (180°C). Line a 9-inch x 5-inch baking tray with parchment paper. You can also use a 9-inch x 9-inch square brownie pan, but the recipe will cook faster, and the brownie will be thinner. Set aside.
Step 1: Prepare the flax egg
- In a small mixing bowl, stir 1 tablespoon of flax meal with 3 tablespoons of hot water. Set aside 15 perc until gooey and an egg-like texture appears. Use in step 3 when the recipe calls for flaxseed egg.
Step 2: Prepare the grated zucchini
- Finely grate 2 large zucchini, skin on, with their ends trimmed, with the thinner grater option on your hand grater, or using the thinner grating blade of your food processor.
- Bring all the grated zucchini into the center of a clean towel. Gather the extremities of the towel and twist to encase the zucchini into the towel and form a ball.
- Twist as hard as you can until ALL the zucchini water is removed. This is extremely important or too much water will make the brownie too moist and fragile.
- Measure 1 cup of packed, drained, grated zucchini and transfer into a large mixing bowl.
Step 3: Make the brownie batter
- In the same mixing bowl, add runny peanut butter, flax egg (the one made in step 1), vanilla, maple syrup, and coconut sugar.
- Stir the ingredients together until consistent. It is liquid and shiny.
- Stir in the unsweetened cocoa powder, baking soda, salt, and melted coconut oil, making sure all the cocoa is incorporated, and no lumps are left.
- Now, stir in almond flour. The batter is getting thick and more difficult to stir. It is what you want.
- Transfer the brownie batter into the prepared baking pan.
- Sütjük 30 perc or until the top and sides are set, crackle, and a skewer inserted in the center of the brownie comes out clean or with few crumbs. Note that if you are using a wider pan, your brownie will bake faster. On the other side, a smaller pan will take longer to bake.
- Remove the pan from the oven and cool down in the pan for 12 perc.
- Use a knife to loosen the sides of the brownies in the pan then use the parchment paper pieces to lift the brownie from the pan to a cooling rack.
- Cool for 30 perc, then, to make it easier to slice and to make it even fudgier, pop it 30 perc in the fridge! I know it sounds left field, but this will set the brownie to perfection, slice without breaking, and the fudgy texture will be enhanced.

- Swap almond flour for the same amount of oat flour or sunflower seed flour or sesame flour.
- Replace peanut butter with sunflower seed butter, the same amount, use fresh seed or nut butter, runny and drippy!















Carine, your recipe is most delicious!
And, very forgiving.
I forgot the egg and coconut oil: it still came out mucho yummy.
I added grated coconut on top and push them into the batter because I was concerned it might burn during baking.
I used two third stevia and one maple for the amount of maple syrup requested.
Used less cocoa powder.
Covered it with a thin layer of grated chocolate. I wanted to use my microplane grater to get chocolate shaves but it came out powdery.
Ate it with fresh raspberries and creme fraiche: ouh la la… sooo good!
Köszönöm
Annyira örülök, hogy ezt hallom!
I already sent my text about what is the fronting on the top of the brownies made out of?
It’s not a frosting but a simple drizzle of melted dark chocolate.
Really good, I didn’t use any of the sweeteners (coconut sugar, maple syrup, etc) and it was still great. I did add an extra flax egg and 1/4 cup carob powder though, and think I might add some dates next time too. Thank you so much for this recipe, I never realised zucchini could be in brownies!
These are soooooooo good! Kid approved, I’ve already made them several times and this will be my go to recipe for brownies.
Köszönöm!
Awesome recipe!! Thank you so much…I subbed plant based egg powder for flax egg and olive oil for coconut oil…turned out great….will be making it again! Also, cooling in fridge did make them more fudgy..
Why do we have to shred two zucchini for one cup? I have about two cups of shredded zucchini left over. Also, the parchment paper burned. Not sure I will make this recipe again.
I used 2 zucchini, but as I explain in the recipe, you need one cup. So feel free to shred zucchini until you have that one cup… Parchment paper burning is hardly because of the recipe, it is more likely due to cheap parchment paper!
Made your brownies and they were delish and incredibly satisfying… thank you very much for sharing ❤️
Köszönöm!!!!
Delicious! We subbed egg for flax because our son has a flaxseed allergy and also added mini chocolate chips too. It turned out delicious! A little more like moist chocolatey cake, but really good flavor and gooey. Love the healthy flour and sugar choices!! Thanks for a yummy treat!
Texture and taste are both, incredibly satisfying. Thank you!
Definitely want to make these but can I cut out one of the sugar options? It’s just way too much sweetness. I’d be happy to add more flax or cacao?
It should work if you add more flaxmeal as a binder, it’s hard to tell you how much as I didn’t try this option yet.
