Zucchini in brownies?

Yes. You heard me. Now before you turn around and run away screaming that you don’t enjoy your vegetables in a brownie hang with me here. Firstly, you don’t even taste the zucchini in the brownies. Secondly, the zucchini is the secret ingredient to making an ultra moist decadent brownie that is so fudgy. Thirdly, you get to sneak in an extra serving of vegetables while having your dessert! I really mean it when I say that these are the best zucchini brownies from scratch!

These zucchini brownies are honestly better and easier than boxed brownies. They are homemade and all you have to do is throw all the ingredients in a bowl and mix it up and bake. There are no fancy steps or equipment ( I hate cleaning up so I make sure all my recipes are super simple hehe). Plus you get the added bonus of them being low-calorie and more nutritious than traditional brownie recipes.

Low calorie brownies?

Zucchini brownies are not only more nutritious than traditional varieties as they have no-butter, less fats and no-flour! Lower in calorie and high fibre, 5 of these brownies are the equivalent to one Starbucks brownie! I like to stick to a regular Starbucks coffee and bring my own brownies 😉

If you’re looking for more low-calorie brownie recipes, my fudge Nutella brownies or brownie bites are also some delicious healthy brownie recipes!

Oat flour- I like to make my own oat flour by blending rolled oats in a high speed blender to form a flour like consistency!

Grated Zucchini- Be sure to drain your zucchini of excess liquid! I like to dab my grated zucchini with a paper towel to get excess liquid off

Cocoa powder-A key ingredient to any chocolate brownie recipe

Granulated sweetener of choice-I like to use monk fruit sweetener, but any granulated sugar will work! If you do not want the brownie recipe to be refined sugar free, normal cane sugar works great as well!

Milk of choice– I like to use almond milk ( as i am slightly lactose intolerant!). You could use any milk of choice preferred. Cows milk works well too!

Chocolate chips (melted) I melt my chocolate chips in the microwave in 20 second intervals and stir in-between!

Egg You could replace this with a flax egg if you’re vegan. A flax egg is made by mixing 1 tablespoon flax seed powder with 3 tablespoons water.

Vanilla extract-You can replace this with vanilla essence but vanilla extract just adds that extra flavour to it!

    Hey hey!

    Thank you for your recipe!

    A quick suggestion, since most of the other ingredients had gram measurements, it would have been nice if the zucchini one did as well.

    It was a bit unclear to me if it was 1/2 pre-drained or drained… End result is I think I put in a bit less zucchini and they were a bit dry.

    Will definitely try with more zucchini next time 🙂

    Thank you!

      Thank you so much for the suggestion! 🙂 I have no idea how i forgot to add the gram measurement for the zucchini! But it is 100g after draining 🙂
      So sorry about this, and thank you for bringing it to my attention

    These brownies came out so good! I also added a little bit of vegan cream cheese to the frosting recipe and it tasted good

    • Wholesome_lee

      I am so happy to hear! Sounds delicious to add the vegan cream cheese- must try! x

  3. Nabila

    Are there substitutes for granulated sweetener, like honey? If so, how much would you recommend we put in?

    • Wholesome_lee

      You could use honey if preferred 🙂 I would use the same amount x
