Summarize the following:
This can take anywhere from 5 to 15 minutes, depending on how hot the chocolate was when the spoons were dipped in it and how thick that layer is. If you want to add any toppings to the spoons, do that before you place them in the refrigerator, or the chocolate on your spoons may not hold them together. To prevent the chocolate from melting, be sure to store the spoons in a cool cupboard or in the fridge. You can store them in the freezer, but the chocolate may crack and dry out if it is left for more than a few weeks unsealed. If sealed, the chocolate should last for up to a year. Keep the spoons in a sealed container if you choose to store them in the freeze to keep the chocolate from drying out.

Summary:
Refrigerate the chocolate spoons until the chocolate hardens completely. Store the chocolate spoons in the fridge or a cool, dry place.
