Preheat a non-stick skillet over medium-low heat.

In a large mixing bowl, combine flour, baking powder, cinnamon, and sugar (if using).

In a separate bowl, beat egg whites.

Add applesauce to the egg whites and whisk.

Slowly add milk to the applesauce mixture and whisk well.

Stir the flour mixture into the wet ingredients.

Whisk until just combined; do not overmix.

Drop 1/4 cupfuls of batter onto the heated skillet.

Grill until bubbles form on the surface.

Turn the pancakes and grill until lightly brown.

Serve with honey and hot coffee.
