In a medium mixing bowl, whisk together the flours, sugar, baking powder, baking soda, salt, and cinnamon. Set aside.
In a large mixing bowl, whisk together the egg white, almond milk, vanilla extract, and mashed banana. Stir dry ingredients into the wet just until moistened.
Heat a large nonstick skillet or griddle over medium heat and spray with non-stick cooking spray or spread with a little butter. When hot, spoon the batter onto the skillet by the 1/4 cupful. When bubbles appear on the surface of the batter, (about 1-2 minutes), flip pancakes and let cook for another minute or so, or until golden brown.
Serve with maple syrup, nut butter, or whatever else your taste buds desire.
