Gluten Free Sweet Potato Brownies

Gluten Free Sweet Potato Brownies

These fudgy vegan and gluten free sweet potato brownies are best eaten cold, just out of the fridge. The icing on top and the chocolate chips inside give it a slight crunchy texture. And since there is coconut oil in both the brownie dough and the icing, it tastes a bit like a Bounty!

About the ingredients

I used white sweet potato but you can use any type. Some are just softer than others but it’s going to end up being mashed anyways!

Medjool dates are always my go-to dates since I discovered them. I love their soft texture and sweet taste, it’s like eating a candy. If you’re using other dates, like Deglet Noor, which are smaller and less sweet, add a couple more and one tablespoon brown sugar.

I put sliced roasted almonds, if you are allergic or simply don’t like these, they can be substituted with any other nuts – crushed, roasted, caramelized…-, shredded coconut, or double the amount of chocolate chips!

Despite its name, buckwheat flour is gluten free. The protein it contains is of very high quality and it’s also a good source of fiber.

A few tips before starting

There are some things you can prep a day ahead : cook and mash the sweet potato, toast the almonds and soak the dates if too dry. Also, don’t forget to put the coconut cream can in the fridge.

If you don’t have a good food processor like me, you can use one to two tablespoons of the dates water to blend them. I also noticed that it’s easier to blend the dates with my hand blender than with the stand blender.

The dough is pretty thick, use your hands to incorporate the almonds and chocolate chips into it.

I used a 6 inch x 3.5 inch – 15 cm x 9 cm ceramic dish. I didn’t grease it but if you use an aluminum dish, it’s better you do so or use parchment paper.

For the whipped coconut cream, don’t forget to put the coconut cream can in the fridge the day before. This way, the fat part is going to get hard and will be easier to separate from the water.

I find the texture of the brownie is nicer when eaten cold, just out of the fridge. Plus you get a bit of a crunch from the chocolate chips, the almonds and the icing. You can also freeze it!
