Mix the wet ingredients (cooked sweet potato, coconut oil, warm water, vanilla, eggs, honey and apple-cider vinegar) together in a food processor. Process until mixed well. It should be a dough-like consistency, with no sweet potato pieces visible.
Mix the dry ingredients together in a mixing bowl, then add the wet ingredients to the dry ingredients. Mix until well combined, but do not over-mix.
Put some olive or coconut oil on your hands and roll the dough into small balls. Two spoons can also be used – scoop some dough onto one spoon and scrape the dough off with the other into a glass baking dish.
Bake for 40 minutes until golden on top.
