Notes
Check out info before recipe for more tips, tricks, and information!To measure flour, lightly spoon it into a dry measuring cup, then use a knife (or something else with a straight edge) to level off the top. Do not scoop the measuring cup into the flour ... you'll end up packing the flour, and the cookies will turn out dry.As you mix the cookies, make sure to stop occasionally to scrape down the mixer's bowl and paddle with a spatula.
