Notes
For lighter cookies, cream until the mixture is light and fluffy, incorporating more air for leavening.

If the cookies begin to dry out, add a piece of apple or bread to the container to help them retain moisture.Cookie Making Tips
Select the right size scoop for accurate portioning. You can use a tablespoon instead if that is what you have.
Drop the cookies onto a prepared baking sheet. The baking sheet can be lined with parchment paper or a silicone mat.
Allow enough space between the cookies for spreading.
Rich cookies will spread out by themselves. However, if the cookie requires it, you can flatten the cookie dough slightly before baking to help it spread.
Allow the cookie sheets to cool between batches before adding the dough.
Cookies bake quickly, so observe to avoid overbaking. It is better to underbake slightly rather than to overbake.
