In a large mixing bowl, mix dry ingredients well.
Blend banana, milk and coconut oil (or alternately, mash banana with a fork and mix all wet ingredients together).
Combine wet and dry ingredients and whisk well.
Heat a teaspoon of oil in a large non-stick frying pan (I use number 5 on an electric stove). When hot, spoon a ladle-full (eg. 1/4 cup) of batter onto the frying pan.
Cook until pancake surface is bubbled and the edges appear dry (two minutes or so). Carefully flip pancakes and cook until browned on the underside, around one more minute.
Serve with your favourite pancake accompaniments.
