The shelf life of cakesicles can vary depending on the specific ingredients used and how they are stored. Here are some general guidelines on how long cakesicles can last: Freshly Made Cakesicles can be enjoyed at their best for about 2 to 3 days when stored properly. To extend their shelf life, you can store cakesicles in an airtight container in the refrigerator they can last for up to 1 week. For longer-term storage, cakesicles can be frozen. Place them in an airtight container or wrap each individually in plastic wrap, and then place them in the freezer. When properly stored in the freezer, cakesicles can last for up to 2 to 3 months.
