Forget the flora, nourish yourself! This cookie combines coffee grounds with all sorts of random snacks, savory and sweet, to form one large eco-treat.
The recipe for such a cookie was floating all about the internet a while ago so you can easily make it yourself if you can't get to Milk Bar.
I was glad to be able to buy one from the source and save some partially hydrogenated cottonseed oil-- because we wouldn't want that to go to waste.
