Ruth Wakefield popularized chocolate chip cookies at the Toll House Inn in Whitman, Massachusetts, in the late 1930s. This soft and chewy version uses the classic combination of butter, two kinds of sugar, egg, vanilla, and chocolate, with more brown sugar than granulated sugar for a tender, chewy center.
Crisp edges surround soft, chewy centers. Brown sugar gives the cookies a warm, caramel-like flavor. The 12-cookie batch makes three cookies per serving.
Tips
Beat a whole egg, then weigh out 33 g for this small batch; save the remainder for another use.
Measure the flour by spooning it into the cup and leveling it off to avoid dense cookies.
Take the cookies out while the centers still look a little soft; they will set as they cool.
