Allow to cool briefly and then lift them off, one at a time. At this point they will be pliable and bend. Lay them one at a time over the handle of a wooden spoon and roll it around it. They will set hard very quickly. As you go along, should the remaining biscuits have firmed too much to roll, just return them briefly to the oven.
You can eat them as they are — they are excellent, for example, with ice-cream — or fill them with whipped cream.
