For chocolate chip cookies or any cookies with mix-ins

Add chocolate chips or other mix-ins to the dough (as much as you want), either while the dough is still in the mixing bowl or folded in with a spatula.

Working with about 1 tablespoon at a time, roll the dough into balls and transfer them to a baking sheet (either nonstick or parchment-lined). Press down to flatten the cookie slightly.

Bake 9 to 11 minutes, until the bottom is just starting to turn golden.

Cool the cookies on the baking sheet, on wire rack.
