Preheat oven to 375 degrees.
Boil sweet potatoes in salted water in a pot for 10-15 minutes or until you can stick a fork in the center.
Drain and cool.
Grate the potatoes into a bowl.
Place the flours, panko and cinnamon in a bowl and stir to combine.
In a small bowl, add egg and whisk.

Roll the tot in whisked egg, then the flour/panko mixture.
Place onto a sprayed baking sheet and coat evenly with cooking spray.
Bake for 15 minutes or until golden.
