Directions

1. Preheat waffle iron according to manufacturer's directions. In a medium bowl combine sweet potatoes, buttermilk, egg and oil. In another bowl combine pancake mix, sugar and cinnamon. Stir sweet potato mixture into dry pancake mixture. Batter will be fairly thick.
2. Coat waffle iron with nonstick cooking spray. Spoon 1/2 to 3/4 cup of the batter into waffle iron; close the lid and cook until crisp. Remove waffles and keep warm; repeat with remaining batter. Sprinkle with powdered sugar, if desired, and serve.
