Rich, fudgy, and deeply chocolatey — these Vegan Sweet Potato Brownies are naturally sweetened, gluten-free, and secretly good for you. No flour, no refined sugar, no eggs — just one bowl and simple ingredients for a brownie that tastes indulgent but is made from real food.
I started making these brownies when I was craving something chocolatey but wanted to sneak in a bit more nutrition — sweet potato does exactly that, giving these brownies their signature fudgy texture without needing any flour or eggs. The first time I brought them to a gathering, nobody could believe there was sweet potato hiding in there. Now they’re one of my most-requested treats, even among friends who aren’t vegan.
These brownies are rich, decedent, chocolatey, flour free, gluten free, with no refined sugars- what is not to like?! They are the perfect guilt-free treat to satisfy any chocolate cravings you may have. These brownies have been requested many times by my dairy/ egg-eating friends who say they think they taste better than any non-vegan brownies they have tried! Try serving with dairy-free vanilla ice-cream, vegan cream (like oat cream) and dark chocolate sauce for an extra treat!
Ingredients
- Sweet Potato– This is the key ingredient that makes these brownies moist and fudgy! They are also a great egg replacement in certain recipes. I peel and boil the potatoes in medium sized piece then blend them in a food processor to make them super smooth. Alternatively, you can bake the potatoes in the oven and scoop out the middle, but ensure they are baked through and completely soft in the centre.
- Maple Syrup– My favourite sweetener due to it being rich in antioxidants and minerals! I used 100% pure maple syrup. It also adds to the brownies’ gooeyness!
- Peanut butter– I love the flavour of peanut butter, but this can easily be substituted with almond butter. I do like to use ‘crunchy’ peanut butter to add some texture to brownies, and with no added sugar or salt.
- Cocoa Powder– For the rich, chocolate flavour, use unsweetened cocoa powder. I often used ‘Hersheys’ cocoa powder, or another good quality brand.
- Oat flour– I LOVE using oat flour as a substitute for all-purpose flour due to it being naturally gluten free, high in fibre and packed with nutrients. I make my own oat flour by blending rolled oats well in a food processor.
If you love a rich chocolate fix, you’ll also want to try my Vegan Avocado Chocolate Mousse — another sneaky-healthy dessert that never fails to impress.
FAQs
Not at all — the sweet potato adds moisture and fudginess, but the cocoa powder and maple syrup keep the flavour rich and chocolatey.
Yes — swap the peanut butter for sunflower seed butter or tahini for a nut-free version.
Store in an airtight container in the fridge for up to 5 days, or at room temperature for 2 days.
Yes — they freeze beautifully for up to 3 months. Slice before freezing so you can grab a piece straight from the freezer.
Maple syrup gives the best texture, but agave or date syrup will also work as a substitute.
