Yes! Like regular butter, you can stash your cinnamon butter in the freezer wrapped in plastic or an airtight container for up to 6 months. Thaw in the refrigerator. If you want to be able to cut off chunks to thaw as you need them, I recommend shaping the butter into a log, wrapping it in plastic, and freezing it. Then, you can simply slice off as much as you need, leaving the rest frozen.
