This takes some time to prepare, but is well worth it. It also has elements of a candy-making recipe in it, so I am guessing that if you are an experienced candy-maker, then you are going to be able to finish it faster than I - this is the only kind of candy making recipe that requires knowledge about "soft boil stage" that I have used so far. So it took me about an hour to finally perfect it the first few times, so that is what I'm using for the prep time!! Cooking time is the mimimum time needed for the cookies to chill. I usually leave them in overnight, though.
