Seal up the bundle, roll it back and forth a couple times to smooth it out so one side isn't flat from resting on the counter, and place it in the freezer to chill for about 15-20 minutes. You just need the dough to firm up a bit so it is easier to roll into a bunch of little balls.
Line two baking sheets with parchment paper or silpats. Remove the logs and using a sharp knife slice 1/2 inch slices of dough. If you prefer flatten cookies you can simply place the rounds of dough on the prepared baking sheets. If you want a rounder cookie (this is what I did for most of mine) roll the sliced cookie dough between your hands to make a small ball and place on the the prepared baking sheet.
