Combine flour, vegan brown sugar, baking powder and salt in medium bowl.
In a separate bowl combine oats, soy milk or water, egg replacer and applesauce. Whisk until smooth.
Pour wet ingredients over dry. Whisk together. Add protein powder and whisk again. Add more soy milk or water until desired consistency is reached.
Spray non-stick pan with cooking spray over medium high heat. Pour about 1/3 cup of mixture onto pan. Flip when the top starts to bubble, or after a minute or two. Cook until both sides are evenly browned.
The mixture should make 2 stacks of 3 medium/large pancakes. Spoon out some applesauce over each pancake in stack. Sprinkle entire plate generously with desired amount of cinnamon.
Note: These pancakes may be slightly gooier on the inside than normal because of the protein powder. Tastes great though!!
