Cut the crusts from the bread slices. Beat the eggs loose together with the cream, milk and sugar, in a deep plate. Wallow the bread slices into the egg mixture. Let the bread lie in the mixture so it can absorb the egg mixture. Hold the mango lengthwise and cut the fruit on both sides, as closely as possible of the seed. From here, cut or scoop out the flesh out of the skin and cut the mango flesh into small cubes. Divide the mango and the shredded coconut on to two slices of bread. Cover with the other two slices of bread and press the edges together. Melt a knob of butter in a frying pan and bake the bread on both sides, over high heat, until golden brown. Dust a bit of icing sugar over the French toast and serve hot. Enjoy!
