Unlike in recipes for chewy cookies, we used more butter and less brown sugar to produce the ideal thin and crisp cookie.

Ingredients
Preparation
Step 1
Preheat the oven to 375°F, with racks in the upper and lower thirds. Line two large baking sheets with parchment paper; set aside. In a medium bowl, whisk together the flour, baking soda, and salt; set aside. In the bowl of an electric mixer fitted with the paddle attachment, beat the butter and both sugars on medium speed until light and fluffy, about 3 minutes, scraping down the sides of the bowl as needed.
Step 2
Add the vanilla, whole egg, and egg white. Beat on low speed until well combined, scraping down the sides of the bowl as needed, about 1 minute. Add flour mixture in two batches; mix until just combined. Mix in chocolate.
Step 3
Shape 2 heaping tablespoons of dough at a time into balls and place about 1 1/2 inches apart on prepared baking sheets. Bake, rotating sheets halfway through, until cookies are golden brown, about 18 minutes. Transfer parchment and cookies to a wire rack to cool completely. Cookies can be kept in an airtight container at room temperature for up to 4 days.
