Heat the butter in a frying pan and add the slices of bread, one at a time. Cook for a minute or so until the underside is golden then turn and cook the other side for the same until golden. Remove from the pan and sit them on a plate and continue cooking each slice of coated bread.
Now dust the slices with the cinnamon sugar – Drizzle over melted chocolate, slice in half and serve.
