Use a food processor or blender to grind the oats into a fine flour.
Combine the flour, baking powder, salt, cinnamon, and nutmeg in a bowl.
In another bowl, stir together the buttermilk, yogurt, eggs, sweet potato, and maple syrup.
Stir the wet ingredients into the dry until just combined.
Spray and heat a skillet or pan over medium heat. Use a ¼ cup measuring cup to drop batter onto the skillet. Bake 4-5 minutes on each side, or until nicely browned.
Serve with pure maple syrup.
