Melt the butter in a non-stick frying pan over a low-medium heat. Meanwhile, add the banana, egg, flour and baking powder to a blender and blitz for 20 seconds.
Pour three little puddles straight from the blender into the frying pan. Cook for 1 min or until the tops start to bubble, then flip with a fork or a fish slice and cook for 20-30 seconds more. Repeat with the rest of the mixture to make three more pancakes.
Serve the pancakes with chopped strawberries or banana and a splash of maple syrup, if you like.
