I needed a really good version, and this one from Epicurious is it: Preheat oven at 350. In a mixer bowl, mix 14 tbsp cold, chopped butter, 1/2 cup dark brown sugar, 1/2 cup light brown sugar, 3/4 cup white sugar, and let it all mix. (Could have also used 1 cup dark brown sugar). Increase the mixer speed to medium and cream for about 7-8 minutes (actually time this). Add 2 tbsp milk, 1 tsp vanilla and 1 egg and mix for 2 more minutes. Add 1/4 tsp each baking powder, baking soda and table salt. Add 2 cups of A.P. flour and mix until combined. Run your knife through 1 pack (10 oz) semisweet chocolate chunks (from TJs), and fold into the dough. Scoop the cookies 2-3 inches apart on a foil lined cookie tray, and bake for 10-12 minutes (turn the sheet once during baking). Once the edges are slightly brown, they're done. Do not over bake. For some of them, I also sprinkled some fleur de sel on some of them, and they tasted really good.
