ingredients:
  • 1¾ cups unbleached all-purpose flour (8¾ ounces)
  • ½ teaspoon baking soda
  • 14 tablespoons unsalted butter
  • ½ cup granulated sugar
  • ¾ cup packed dark brown sugar
  • 1 teaspoon table salt
  • 2 teaspoons vanilla extract
  • 1 large egg
  • 1 large egg yolk
  • 1½ cups milk chocolate chunks
directions:
  1. Adjust oven rack to middle position and heat oven to 375 degrees. Line 2 large (12 x 17-inch) baking sheets with parchment paper. Whisk flour and baking soda together in medium bowl; set aside.
  2. Heat 10 tablespoons butter in 10-inch skillet over medium-high heat until melted, about 2 minutes. Continue cooking, swirling pan constantly until butter is dark golden brown and has nutty aroma, 1 to 3 minutes. Remove skillet from heat and, using heatproof spatula, transfer browned butter to large heatproof bowl. Stir remaining 4 tablespoons butter into hot butter until completely melted.
  3. Add both sugars, salt, and vanilla to bowl with butter and whisk until fully incorporated. Add egg and yolk and whisk until mixture is smooth with no sugar lumps remaining, about 30 seconds. Let mixture stand 3 minutes, then whisk for 30 seconds. Repeat process of resting and whisking 2 more times until mixture is thick, smooth, and shiny. Using rubber spatula or wooden spoon, stir in flour mixture until just combined, about 1 minute. Stir in milk chocolate chunks.
  4. Divide dough into about 20 balls, each about 1½ tablespoons. Arrange 2 inches apart on prepared baking sheets.
  5. Bake cookies 1 tray at a time until cookies are golden brown and still puffy, and edges have begun to set but centers are still soft, 10 to 12 (for slightly underbaked like in photo) minutes, rotating baking sheet halfway through baking. Transfer baking sheet to wire rack; cool cookies completely before serving.
