Bring water to a boil. While the water heats, peel sweet potatoes. Cut them into fairly large pieces that will fit in your food processor for grating. Cook them for approximately 10 minutes. If you’re planning to grate them by hand, leave them whole and cook about 15 minutes. Drain and cool them. If you plan to bake these right away, preheat oven to 375 degrees.
While potatoes are cooling, make the coating mixture. Combine the dry ingredients in a food processor or blender and process until mixed. Melt butter in a microwave safe bowl. Pour dry coating ingredients into the bowl and mix with the butter. Set the coating mixture aside.
Grate potatoes. (I found it easiest to use the food processor). Scrape the grated potatoes into a bowl. Add cinnamon and sugar and mash it into the potatoes. It won’t be exactly like mashed potatoes. It will be a lumpy mixture that you can form with your hands. If you’re saving the mixture for the next day, just put it in a sealed container in the refrigerator.
Use about 1 tablespoon sweet potato mixture to form each tot. Shape the mixture into rounded oblong shapes about 1 inch long. Roll the tots in the coating.
Spray a baking sheet with non-stick spray. Place tots on the sheet and bake at 375 degrees for 20 minutes. Take them out, turn them over and bake another 15-20 minutes.
