Keep the dough cold while working with it. Take the dough out of the fridge or freezer and let it sit to soften slightly. Roll it into sheets (I make mine about 3/16″) and then put the sheets back into the fridge for 30 minutes. This helps the dough to relax, which will help to prevent the cookies from becoming misshapen in the oven. Cut out the cookies while the dough is cold so that they keep their shape. Once the cookies are cut from the sheets, put them in the freezer to chill for another 15 minutes. At this point you can wrap the cookies up and freeze them for later or bake them if you’re ready to decorate. I wrap my cookies in sets of 8 because that’s how many I can fit onto a half sheet pan at once. It makes it easy to just grab what I need from the freezer.
