Warm the milk and dissolve the chocolate and cocoa in it.
Mix the egg and yolks with the sweetener and vanilla (not frothy), then slowly pour in the warm chocolate milk.
Pour into small ramekins or heatproof glasses, stand in a roasting tin and pour hot water into the tin (bain-marie); bake for 25-30 minutes until set at the edges.
Once cool, chill for 2 hours; they keep 3 days.
