These Whole Wheat Zucchini Brownies are healthy brownies that are not too sweet and are perfectly fudgy brownies. Made with freshly grated zucchini, white whole wheat flour, and chocolate chips. I love adding zucchini to dessert recipes like Zucchini Chocolate Chip Cookies, or Chocolate Zucchini Bread.
Fresh zucchini is one of those vegetables that can be used in a million different ways – sweet or savory it’s perfect. In the summer months, it feels like all of my neighbors are begging me to take their extra crop off their hands and the perfect way to use them up is by making the best zucchini brownies. For this recipe for Whole Wheat Zucchini Brownies, I went full-on sweet and it turned out perfectly. The brownies are made with white whole wheat flour and sprinkled with just a little bit of powdered sugar. I’m such a sucker for that sweet little sprinkling on top. If you’re feeling frisky you could even serve it with a big scoop of ice cream or top with a rich chocolate frosting.
Don’t worry when you make these if the brownie batter seems a bit dry. Let it rest for just a minute and the zucchini will release enough moisture to make the batter just a little more wet. Trust me, it will look weird at first but totally come together in the end!

How to make Fudgy Zucchini Brownies
- Preheat your oven to 350º F degrees and spray a 9×9 pan with non-stick spray.
- In a large mixing bowl add sugar, oil, and vanilla bean paste. Stir to combine.
- Add dry ingredients, whole wheat flour, cocoa powder, baking soda, and salt to wet ingredients. Stir to combine.
- Add in the zucchini and chocolate chips and stir to combine. The mixture might look a little dry but let it sit for just a few minutes and the zucchini should release some water and make the mixture a bit more moist.
- Add the mixture (it will be thick) to the prepared baking dish, press to the sides, and smooth so that the brownies are equally distributed. Bake for about 25 minutes or until the sides of the pan are set and the center is just slightly soft. Let cool before slicing and sprinkle with powdered sugar or a fudgy frosting, if desired. Store brownies in an airtight container.
