Note 1: When measuring the flour, do not press the measuring cup into the bag of flour, as overfills the measuring cup. Spoon the flour into the cup and then level. The flour should completely fill up the cup without being packed in. Measuring the flour correctly is going to give you the most success with this recipe. If the cookies are spreading too much you likely didn't add enough flour; if the cookies are cakey and too thick, you have used too much flour.
