Way past my comfort zone" is funny to me @cameronwood because I bought a vacuum sealer last year and now I'll eat freezer stuff from like 2020 without a second thought. But yeah maybe don't push it that far with cookie dough, the butter gets weird eventually.
A year? You froze cookie dough for a whole year and still ate it? I wouldn't trust anything in my freezer that long... that's way past my comfort zone. I get nervous after a couple months.
