While the dough freezes, preheat your oven to 325 degrees, and line two baking sheets with parchment paper. Slice each log into cookies about 1/4-1/2 inch thick. Work through one log at a time, keeping the others chilled while you work, and place the cookies onto your baking sheet. They will not spread while baking, so they can be pretty close together. Bake for 10-12 minutes, or until the edges have just barely started to become golden brown. Cool completely, and enjoy!
