In a medium saucepan, melt the butter over medium heat, then bring it to a boil. Once it starts boiling, swirl the pan constantly until the butter passes foamy phase and becomes a deep amber color. Remove from the heat, and allow the butter to cool slightly. Transfer the butter to a mixing bowl.1 cup (2 sticks, 226 g) unsalted butter
In a large mixing bowl, whisk together the flour, baking soda, and salt. Set aside. 2 ½ cups (300 g) all-purpose flour 1 teaspoon baking soda 1 teaspoon fin sea salt
To the butter, add the brown sugar, granulated sugar and whisk to combine. Then add in the eggs, vanilla and milk and stir to combine. 1 cup (213 g) packed light brown sugar ½ cup (100 g) granulated sugar 2 large eggs 2 teaspoons vanilla extract 1 Tablespoon milk
Add in the dry ingredients. Stir using a wooden spoon or spatula until the dough comes together and the ingredients are evenly incorporated. Stir in the chocolate chips. Cover and chill the dough for at least 1 hour. 2 cups (340 g) semi-sweet chocolate chips
Position a rack in the center of the oven and preheat the oven to 350°F(180℃). Line a baking sheet with parchment paper.
Using a medium (2-tablespoon) cookie scoop, drop the dough 2 inches apart on the baking sheet.
Bake for 10 to 12 minutes until the edges are lightly golden and tops are puffy but set.
Allow the cookies to cool for 5 minutes on the baking sheet, then transfer them to a wire rack to cool completely. If desired sprinkle a small amount of flaked sea salt on top of the cookies as they are cooling. Store airtight at room temperature for up to 3 days flaked sea salt
