Cookies revived

We'll I've made a post before about perfecting my cookies. They were too flat and I researched what would do that and changed the recipe to find fluffier cookies. But talking to a friend (and fan of my cookies) he asked me why my perfect cookies needed perfecting?  Then I remembered that they once were fluffy. What changed? I got a Kitchen Aid. LOVE OF MY LIFE. but, I realized it was the source of my problem. Too much mixing. I tried my original recipe again changing only the amount of mixing. Ahhhh! That was it!  Taste and fluffiness are just like I remember. Thanks for the reminder Ryan!
