Split the croissants. Stuff each one with a couple of slices of crispy smoked bacon and some sliced banana. Whisk the eggs, milk and maple syrup. Dunk the croissants into the mixture, pressing them under the liquid until it’s all been absorbed.
Heat a knob of butter in a large frying pan. Cook the filled croissants for 3-4 mins on each side, pressing down with a fish slice to make sure the whole surface touches the pan. When cooked through, dust with icing sugar and serve with maple syrup.
