Whisk the eggs in a small bowl.
In another bowl, lightly mash the bananas with a fork. Add the egg, baking powder, vanilla or cinnamon, then combine.
Heat a little oil in a heavy-based frying pan or pancake pan over medium heat. Add approx. 2 Tbsps of the batter and make a circular shape with the spoon and tilting the pan. When the top looks set ( after about a minute or so) flip it over and cook for another minute. Try to make about 3-4 pancakes at a time. The batter should be enough to make about 8-10 pancakes (in two batches).
Serve warm, topped with maple syrup, yogurt and/or fruit compote (if you like).
