Yes, this fudge freezes and thaws well — it will stay fresh for probably a good year — nothing really to go bad, here.
the thing with freezing chocolate, though, is that the sugar blooms, sometimes, causing the chocolate to turn white. This happens if any moisture gets in the package. My suggestion would be to freeze the chocolate in one big piece, and then use a vacuum seal bag or press and seal — and then wrap it tightly.
I hope this helps a bit!
