Sift all dry ingredients together to ensure uniformity. Combine the egg, vanilla, milk & oil. Add to dry ingredients. Add the banana to the ingredients and mix well. Cook on heated griddle or skillet. Once the top is bubbly and the underside is brown turn over once. Once the bottom is brown remove from heat and top with favorite syrup or topping. Note: Due to the amount of bananas in the mix the pancakes will take longer to thoroughly cook than a normal pancake.
