 I grew up with tin skull holly cookies, but did you know? You can also use a Dutch oven. Here's what you're going to do. Put your cookies in layers, in between each layer, add a piece of parchment, when you get to the very top, put a piece of bread. This will go stale instead of the cookies. Put your top on. Everything will last for about a month, but I don't think your cookies will make it that long.
