Notes
Chilling the dough is required or the cookies will spread and flatten during baking. To freeze the dough for later, scoop cookie dough onto a baking sheet and freeze for one hour before transfering the dough to a freezer safe bag and freezing for up to 3 months. Bake directly from the freezer (do not thaw), adding 1-2 minutes to the bake time as needed.
