Notes
What can I use instead of popsicle molds?Disposable cups like Dixie cups or an ice cube tray with larger slots can work well. Once they are made and frozen, run the bottom and sides of the container(s) under hot water. This will help the popsicle release from the mold.Storage TipsKeep your homemade popsicles fresh and frost-free with these storage tips:
Store them in the freezer for up to a month.
To avoid freezer burn, store them outside the molds in an airtight container that is freezer-safe.
