For the chewiest texture, pull the cookies when the centers still look a touch soft; they’ll finish setting as they cool. If your kitchen is warm, chill the portioned dough balls for 20 minutes before baking to control spread. Dough balls can be frozen for up to 2 months; bake from frozen, adding 1 to 2 minutes to the bake time. Store baked cookies airtight at room temperature for 3 to 4 days.
