Oh my god, I find the thin mints utterly irresistable. That's why they are never ever allowed in my house again. Not as long as I live alone, anyway. Don't like any of their other cookies, but the thin mints... are... divine.
I found some homemade knockoffs a while back that are pretty delicious too, almost as good, and the advantage is that you can make a tiny batch and cut back on the preservatives, if you're baking inclined like I am. I can't post the recipe though, with too few posts. I will when I can, though!
Here's the recipe!
