The easiest way to make banana pancakes is to just blitz an over ripe banana with your measured milk and egg and make as the usual Pancake recipe
If you wish to make them a little lighter due to the banana pop in a little extra vinegar and sugar (both to counter act each others tartness to sweetness).
Feeling a bit fancy add a sprinkle of cinnamon as well to the batter. Or top with cinnamon sugar instead of ice cream and maple or chocolate syrup. Also nice with just butter.
