You guys, I've made a lot of cookies in my 29 years and many a chocolate chip cookie. This one is a recent find (thanks, Hailey!) and I will be baking these for years to come.
WARNING: They do require some planning head. I didn't refrigerate the dough as long as it said and they still turned out awesomely delicious. Next time I will let it chill as directed. Also, I don't ever sift my dry ingredients. Ever. My cookies always turn out just fine.
