Golden-edged, soft and chewy chocolate chip cookies with bakery-style height and gooey centers.
2 1/4 cups all-purpose flour 1 tsp baking soda 1/2 tsp fine salt 3/4 cup unsalted butter, melted and cooled 5 min 3/4 cup packed light brown sugar 1/2 cup granulated sugar 1 large egg 1 large egg yolk 2 tsp pure vanilla extract 1 1/2 to 2 cups semi-sweet chocolate chips or chopped chunks Flaky sea salt, optional
1. Preheat oven and line baking sheets. Whisk flour, baking soda, salt. Whisk melted butter with sugars. Whisk in egg, yolk, vanilla. Fold in dry ingredients. Fold in chocolate chips. Scoop tall mounds on parchment. Bake until edges golden, centers just set. Cool briefly on pan, then rack. Finish with sea salt, optional.
For extra chew, keep brown sugar higher than white. Scoop taller portions to avoid flat cookies. Chill portions briefly if dough feels loose. Mix chips and chopped bars for varied pools. Store airtight; rewarm to refresh texture.
