In a small bowl, combine the egg whites, applesauce, and almond milk and mix well. In a second bowl, combine the protein powder, oats, coconut flour, baking powder, and cinnamon. Gradually add to the egg mixture and mix just until combined. Gently fold in the diced apple.
Heat a skillet on medium heat. Drop 1 teaspoon of the coconut oil onto the hot skillet. Once melted, pour about 1/4 cup of the batter into the pan. Cook about 3 to 4 minutes, or until pancakes begin to bubble in the center. Carefully flip and cook for another 2 to 3 minutes. Once cooked, remove pancake from the pan and repeat the process until all the batter has been used. Grease the skillet with the remaining coconut oil in-between cooking the pancakes as needed.
Serve hot, if desired top with maple syrup, honey, fresh fruit, or your favorite jam!
