Step 1

Preheat the oven to 350°F

Step 2

Heat the butter in a small saucepan until it turns an amber color and smells nutty

Step 3

For a deeper flavored cookie, we let it get dark brown

Step 4

Transfer the brown butter to a small heatproof bowl and set aside to cool to room temperature, about 15 minutes

Step 5

Meanwhile, mix together the flour, baking soda and salt in a medium bowl

Step 6

In a large bowl, mix together the brown sugar and granulated sugar with the cooled brown butter until well incorporated and slightly fluffy

Step 7

Add the vanilla and mix

Step 8

Add the eggs and mix until the mixture is fluffy and turns a lighter brown color

Step 9

Pour the dry ingredients into the wet ones and mix until just incorporated

Step 10

Don’t overmix—flour streaks are okay

Step 11

Add the dark chocolate and chocolate chips and mix JUST until they are incorporated

Step 12

Let the dough sit, covered, at room temperature or in the fridge, for at least 30 minutes

Step 13

It can also be stored in the fridge overnight

Step 14

Spoon the dough onto baking sheets, leaving adequate space in between

Step 15

We usually portion out 3 tablespoons per cookie, which yields 10 to 12, but you can make them any size you like

Step 16

Bake until golden brown around the edges with slightly underbaked centers, about 10 to 12 minutes, assuming they are about 3 tablespoons each

Step 17

If you prefer a crisper cookie, bake them longer

Step 18

Once the cookies are out of the oven, top each one with 2 to 3 dark chocolate chunks and let melt (about 2 minutes)

Step 19

Generously sprinkle the cookies with sea salt and let sit for about 20 minutes before serving

Step 20

This will allow the cookie to firm up, yet still be warm, resulting in a crunchy exterior and chewy, soft interior

Step 21

Note: To fully stop the baking process and firm up the cookies faster, after salting the tops, carefully transfer them with a spatula to a clean baking sheet or platter and freeze for 10 minutes

Step 22

Let sit at room temperature for 5 minutes, then enjoy!
