ROOM TEMPERATUREWhen storing cupcakes at room temperature, make sure to store them in an airtight container and a cool, dry, and dark place. Store the cupcakes out of direct sunlight and make sure they are not exposed to any excessive moisture.
REFRIGERATORThe simplest answer is to store the cupcakes in an airtight container. This will help prevent the cupcakes from drying out and protect them from the moisture inside of the fridge. And, the colder temperatures will also slow the deterioration of these cakes.
