You don't have to make a croquembouche with caramel, although it is the most traditional, when I made one i put custard in the choux and stuck it together using cardboard and silver foil and chocolate as children tend to prefer that.
It is also a great alternative for people who have never made it before as it is easier to put together as chocolate really hardens up in the fridge.
