I tend to combine two or more recipes together. So, my favorite chocolate chip cookie is a combination of the Toll House Recipe and Alton Brown's recipe. I do not melt the butter first. And, I reduced the amount of flour and omitted the milk. The ingredients are: 1 c butter 1 c brown sugar 1/2 c sugar 1 egg 1 egg yolk 1 tsp vanilla 2 c ap flour 1 tsp baking soda 1/2 tsp salt 1 1/2 c chocolate chips Very soft and chewy. Best eaten same day. However, for the cafe I wanted a cookie that would stay soft longer. So, I added back the 1/4 c flour and added 2 tbsp corn syrup (instead of milk). The ingredients are: 1 c butter 1 c brown sugar 1/2 c sugar 1 egg 1 egg yolk 2 tbsp corn syrup 1 tsp vanilla 2 1/4 c ap flour 1 tsp baking soda 1/2 tsp salt 1 1/2 c chocolate chips These stay chewy for longer. I also scoop these into balls, freeze and then bag them. So I usually bake them from frozen and they do fine.
