This is how I went about making them, but you could change the filling to suit your liking.
Once they have cooled, cut each puff in half to form crispy pastry cups.
For the filling, fold together 4 tablespoons of nutella with 4 table spoons of nestle caramel fill (found near the condensed milk in supermarkets). Fill each cup with the mixture before spooning on some whipped cream just to cover the chocolate caramel centre. To finish, drizzle some melted chocolate over the whole batch of cream puffs and transfer them to a serving plate.
Warning: I cannot guarantee you won't be feeling sick after just one bite...
