For years I have used the same chocolate chip cookie recipe because it was so GOOD! Somehow I must have lost the recipe and it turns out that is a good thing. I found a new recipe that tastes even better, but I have to admit I was a little hesitant to try it because it called for a couple of things I'd never tried in any cookie recipe. The recipe called for melting the butter and also for bittersweet chocolate chips. I have to tell you I think I have a new favorite recipe! Click here to try the recipe from America's Test Kitchen.
