In a large bowl mix together the dry ingredients. In another bowl mash banana and mix in pumpkin pie mix through vanilla. Add the wet ingredients to the dry and mix thoroughly. Heat a pan or griddle over medium heat. Spray with cooking spray and pour batter on to form thin pancakes. Cook until golden brown on the bottom, flip and repeat with the other side.
Serve hot topped with powdered sugar, real maple syrup, chopped nuts, fruit or Greek yogurt.
