Chocolate Chip Cookie
A butter cookie studded with chunks of chocolate that hold their shape instead of melting into the dough, crisp at the edge and soft in the middle.

Where it comes from
It was invented at the Toll House Inn in Massachusetts in the 1930s, when baker Ruth Wakefield chopped a chocolate bar into her cookie dough; whether she expected the pieces to melt or hold their shape is disputed.
What cooks argue about
Bakers argue over chilling the dough for a day, which deepens flavor and controls spread, against baking it right away for convenience and a softer, less caramelized cookie.
