How Do You Store Glass Cookies?
Glass cookies should be stored in an airtight container at room temperature. They can be kept on the kitchen counter, in a pantry, or in a cool, dry place for up to a week. To prevent them from becoming soggy, avoid stacking them on top of each other or placing them in a humid environment. For longer storage, they can be frozen for up to 3 months. If frozen, bring them to room temperature before serving.
