Bake in the oven for 13-14 minutes. When they are in the oven, they should bubble up. They are almost done when the bubbling begins to slow down and there should be a slight crispness to the edges. If you pull them out of the oven too soon, they will be chewy and won't harden. If you pull them out too late, they will be burnt/hard and you won't be able to shape them.
Once out of the oven, let them sit for 1 - 1 ½ minutes. They should be cool enough to handle with your hands, but don't wait too long otherwise they will harden and you won't be able to shape them. You also can't touch them too soon because you will burn your hands, and they won't set enough and will break apart. I suggest doing only a few at a time - this way you have enough time to shape the ones you baked before they harden.
You can either shape them into baskets by using mini bowls or small tart pans. Or, you can form them to look like a cannoli using cannoli tubes or wrapping them around a pencil, the handle of a wooden spoon, etc.
Repeat this process with the rest of the dough. Let the biscuits sit at room temperature or in the fridge while they harden completely.
