Saving your cannabis food

Are there ways to save cannabis food. I've mad a lot of things but I always eat them quick or sell 'em all. Can I make a batch of butter/brownies/firecrackers/etc. and save them? Would I just put them in a freezer in a light proof case?
P.S. If there is another thread like this please remove this one and PM me the link to the other. Thanks

I know I put some brownies in the freezer as well as cookies and they lasted. But I also read somewhere that the change in temperatures can break down the THC. Which I also could believe becuase I had another batch of brownies in the freezer but they thawed out two times and then froze again due to not finishing them. But the last time, I dont think they affected me at all for the half gram that was in them each.

I would say dont defrost unless you plan on eating and not keeping it that long. The quicker you can eat and enjoy them the better.
