According to OurEverydayLife, “Heavy cream is good for three to four months frozen at 0 degrees Fahrenheit or less.”
Once heavy cream has defrosted, you will not be able to make whipped cream from it because jagged crystals can develop during the freezing process that may pierce fat globules. If you intend to make whipped cream from your heavy cream, sweeten and whip the cream before freezing.
Portion whipped cream into individual mounds on a wax-paper lined cookie sheet, freeze, and then remove to store in a covered plastic container until ready for use. Frozen whipped cream will keep in the freezer for one to two months.
