Combine sweet potato and melted butter in a large bowl. Add the flour and mix
Roll dough out and using a biscuit cutter cut out the biscuits.
Place on a baking tray lined with baking paper.
Bake in the oven until biscuits are just beginning to brown, about 20 minutes.
To prepare the mashed sweet potato - peel the sweet potato, chop into pieces and cook in water on the hotplates/stove, steam in a steamer or cook in the microwave. Once cooked (soft when tested with a skewer), use a potato masher or fork to mash/squash the potato to as smooth as you can get it.
