Once you’ve made the dough for slice-and-bake cookies, turn it out onto a sheet of wax paper, and shape it into a log.
Wrap the log in wax paper and form a compact roll, twisting the ends of the paper securely. Freeze the dough 2 to 3 hours or until very firm.
To cut the dough into slices, unwrap the dough and cut it into thin slices using either dental floss or a very sharp knife. Place a strand of floss under the log and pull it up over the dough. Cross the ends over as if you were going to tie a knot. Pull tightly to cut the dough. You may need to let the dough soften slightly if you’re using dental floss, but cutting with the floss helps keep the round shape of each slice instead of flattening it out on one side.
If you’re using a knife to cut the slices, use a sharp one, and coat both sides of the knife with cooking spray. This will help you get a nice, clean slice without the dough sticking to the knife. As you slice, rotate the log of dough so that it does not completely flatten out on one side.
Place the slices of dough on a greased baking sheet bake according to recipe directions.
When the cookies are done, gently transfer them from the baking sheet to a cooling rack.
