Step 1

To brown the butter, place it in a small saucepan and cook it over medium heat. Swirl occasionally for 8-10 minutes until the butter becomes foamy and fragrant with little brown flecks throughout. Once it turns brown and smells nutty, remove it from the heat and pour it into a large heat-proof bowl. Let the butter cool down for a couple of minutes.

Step 2

Preheat your oven to 175°C (350°F).

Step 3

Place the skillet with the brown butter back over low heat and stir in the brown sugar and granulated sugar. Mix until well combined and let it cool for a few minutes.

Step 4

Mix the eggs and vanilla extract well into the brown butter and sugar mixture.

Step 5

Sprinkle the all-purpose flour, baking soda, and salt over the wet ingredients in the skillet. Stir until just combined, being careful not to overmix.

Step 6

Gently fold the chocolate chips into the cookie dough until evenly distributed throughout the skillet. Press the cookie dough evenly around the skillet.

Step 7

Place the skillet in the preheated oven and bake for 25-30 minutes or until the edges are golden brown and crisp and the centre is slightly gooey.

Step 8

Allow the cookie skillet to cool for a few minutes before slicing. This will help the cookie set slightly while maintaining its gooey centre. Optional: Sprinkle with sea salt.

Step 9

Serve with a scoop of your favourite ice-cream.
