Preheat the oven to 170 C / Gas 3.
In a large bowl, whisk the egg whites until stiff.
In a double boiler, over just simmering water, whisk together the egg yolks, sugar and vanilla until pale. Fold the yolk mixture into the stiff egg whites.
Combine the flour, baking powder and salt. Sift the flour into the wet mixture and gently fold together in a 'figure eight' motion. Do not over-stir, but ensure there are no lumps of flour.
Tip the mixture into a small cake tin, and place the cake tin in a larger baking dish or roasting tin. Fill the larger tin with hot water so that it comes halfway up the sides of the cake tin. Bake in the preheated oven for 10 to 20 minutes, or until the cake tests done with a skewer.
