Mix the egg and sugar in a bowl. Add the flour, baking powder and salt and mix to a smooth batter with the coconut milk. Leave to stand for 10 minutes.
Meanwhile peel the bananas and cut each one into 4-5 pieces.
Heat the oil in a frying pan, a wok or a deep-fryer. The oil is hot enough when bubbles form on the handle of a wooden spoon held in the oil. Coat the banana pieces in batter and fry in the hot oil over a medium heat for 3-4 minutes until golden brown.
Drain on paper towel. Put into bowls, pour a little honey over and serve hot.
