Melt the chocolate pieces , either in a heatproof bowl over simmering water until melted and smooth , or in the microwave , in short busts .i stirring after each burst until melted and smooth .

Using electric mixers and a clean bowl , beat the cream until soft peaks form .

In another bowl , Using an eclectic mixer , beat the eggs and sugar together in a bowl for 5 minutes , or until thick , pale and increased in size .

Beat the melted chocolate into the egg mixture then transfer to a digger bowl if needed .

Gently fold the prepared whipped cream into the melted chocolate mixture until just combined .

Once mousse has set , remove from the refrigerator and spoon into piping bag and pipe into each individual ice cream cone evenly until full . You can spoon the mousse mixture into the ice cream cones if you prefer .

Garnish with sprinkles , flaked chocolate , cream , anything you desire or just as they are is just as good . Enjoy . :-) .

NOTE : if you want to make it kid friendly , then leave out the rum . :-) .
