First, you'll need some mashed up sweet potato. You can easily peel and boil one large sweet potato and mashed it up.
In the wet ingredients, mix the sugar with the butter and eggs, slowly pour in the milk, vanilla extract. Lastly, add in the sweet potato.
Combine the dry ingredients into a bowl then slowly mix them together until combine. There may be a few lumps from the sweet potato but that's fine.
Heat the waffle iron and do not add the batter until the iron is hot and ready. Spray lightly with cooking oil then place a ladle of waffle batter in. You should get 5-6 waffles from this recipe.
Once the waffles are done.
