Chilling the portioned dough firms the butter so the cookies spread less and get that thick New York bakery style texture; using a mix of chips and chopped chocolate creates pools and pockets for better melt and contrast. If you prefer extra-thick cookies, scoop 3 tablespoons per cookie and extend bake time by 1 to 2 minutes. For chewier centers, pull the cookies when the centers are pale and slightly domed, as carryover heat will finish them. Weighing flour prevents dry, cakey results (target about 300 grams), and cold butter helps mimic the bakery-style mixing method without a long rest. Rotate the pan halfway through for even browning, and always bake from chilled dough for best height.
