Store these fudgesicles in the freezer until serving. They should last for up to 6 months, although I recommend eating them within 3 months to avoid crystallization that can take place in popsicles that are frozen for long periods. Here are my preferred methods of storage that you can try when freezing your fudgesicles: 1. Store them in an airtight Ziploc bag with sheets of parchment paper between them to keep them from sticking to one another. 2. Store them in these super convenient Plastic Popsicle Bags or Wax Paper Sleeves, which can then be stored in an airtight Ziploc bag or container.
