How long does a gingerbread house last?

Gingerbread houses can last for several weeks if they are properly stored in a cool, dry place. To extend their shelf life, gingerbread houses can be wrapped in plastic wrap or placed in an airtight container. If the gingerbread house is going to be displayed, it is important to keep it away from direct sunlight, as this can cause the frosting to melt and the gingerbread to become stale.
