Peel the sweet potato and cook in the microwave until soft, about 5 minutes on HIGH power.
While the potato cooks, combine the oats, stevia, cinnamon, baking powder, and salt into a food processor. Process until the oats have turned into the consistency of flour, and everything is well mixed.
Core and dice your apple, set aside.
Heat a greased griddle or pan to medium high heat.
Once the potato is cooked through, add it to the food processor. Also add the almond milk, vanilla and egg whites.
Process until well combined, and a batter is formed.
Stir in the diced apples.
Drop batter by 1/4 cup spoonfuls, and cook very slowly to ensure that the middle cooks as well.
Cook until golden brown on both sides (5-7 minutes a side) flipping once.
