While one batch of cookies is baking I prepare the next batch on parchment paper or foil. As soon as a batch is removed from a cookie sheet, the next batch, on the paper, is slid onto the sheet and goes right in the oven. Speeds up things a lot!
I make several batches of cookie dough, different kinds, one right after the other, without washing the mixer or measuring utensils. Saves a lot of time. Then I can bake the cookies or refrigerate some of the dough and bake them at my leisure.
