Sweet Potato Brownies

Going on an elimination diet has pushed me to get creative with my baking, and these sweet potato brownies are a result of that. I’d seen recipes using sweet potatoes before but never got around to trying them. Finally, I gave it a go and came up with this vegan and gluten-free recipe. Brownies seemed like the perfect choice because they let you see how the mixture bakes—whether it stays gooey or sets properly. These brownies are cakey around the edges and soft and gooey in the middle. They’re not as rich or chocolatey as dairy-based brownies since they’re cocoa-only, but the sea salt flakes add a luxurious touch. For the flour, I used Sainsbury’s gluten-free plain flour, which worked perfectly. I opted for almond butter to keep the flavour subtle, but peanut butter would work too. And if you want to sprinkle nuts on top, I highly recommend pecans.
