The best classic, chewy chocolate chip cookies have a few secrets. Number one: Instead of using chips, use a mixture of milk, semisweet, and dark chocolate chunks. Allowing the dough to rest overnight or longer for a more nuanced, toffee-like flavor is the second option. Finally, to ensure consistent cookie sizes, use an ice cream scooper. That's everything! With these minor adjustments, the outcome is a textured cookie that is soft and gooey on the inside. Absolutely fantastic!
