These Vegan Zucchini Brownies are rich and fudgy, super moist and secretly healthy. They’re satisfying and nutritious too!
If you’ve never baked with zucchini (courgette) before, you must give it a go! Although it may sound a bit weird to add vegetables to a dessert, grated zucchini adds so much moisture and a wonderful depth of flavour. I’d already made Zucchini Bread and Zucchini Muffins, so decided to try my hand at some Zucchini Brownies!
The zucchini in these brownies creates a beautifully fudgy texture, adds richness and so much moisture, not to mention nutritional benefits!

I can’t wait to try this recipe! One question-is the 150 grams zucchini weighed after squeezing the water or before? Thanks!
Rhian Williams
Thank you! Weighed before squeezing out the water!

These fit the bill when I was looking for vegan, grain-free, no sugar/liquid sweetener brownies. They aren’t at all as sweet as regular brownies, so don’t expect that, but they are a great treat when working on eating clean. I baked them in individual brownie pan so I had 12 squares and wrapped each one in plastic wrap and then set into a larger freezer bag and froze them to take out one at a time when desired. They froze well. I’m doing 6 weeks grain-free sugar-free. Week 1 I wasn’t impressed with the taste but they were ok. I’m on week 5 and they taste really good to me. So part of the issue is definitely taming a sugar tooth to have a palate that appreciates cleaner foods. Thank you so much for sharing this recipe, I’m making it again soon.

Thank you so much, so glad you liked them!

These are pretty good, not very sweet. consistency has varied based on how long I soaked dates, but I like them better in week 5 of being grain free and processed sugar/honey/maple syrup/etc free than I did in week 1. So, as long as you know what to expect these meet a need for a treat that isn’t really a hit for the sweet tooth. I’ve made them more than once so that speaks volumes.
