Melt the chocolate in a heatproof bowl over a pan of simmering water then leave to cool for 10 minutes.
Beat the egg yolks, sweetener and rum into the cooled chocolate.
Whisk the egg whites until just stiff but not too dry then fold into the chocolate.
Transfer the mixture into small serving glasses (shot glasses are ideal) and chill for 1 hour or until set.
