Ingredients:
- 1 cup (225g) unsalted butter
- 3/4 cup (150g) brown sugar, packed
- 1/2 cup (100g) granulated white sugar
- 1 large egg (50g)
- 2 tsp (10ml) pure vanilla extract
- 2 1/4 cups (280g) all-purpose flour
- 1 tsp (5g) baking soda
- 1/2 tsp (3g) sea salt
- 2 cups (340g) semi-sweet chocolate chips
Instructions:
- Brown the butter in a saucepan over medium heat until it foams, turns a deep amber color, and smells nutty.
- Pour the browned butter into a bowl and let it cool for 5 minutes to prevent the eggs from scrambling.
- Cream together the cooled browned butter and both sugars until the mixture is thick and glossy.
- Beat in the egg and vanilla extract until fully emulsified.
- Slowly fold in the flour, baking soda, and salt using a spatula, stopping immediately when white streaks disappear to avoid over-mixing.
- Fold in the semi-sweet chocolate chips.
- Press the dough evenly into an ungreased 10-inch cast iron skillet.
- Bake at 350°F (175°C) for 20–25 minutes until the edges are golden brown and set, but the center still jiggles slightly when the pan is shaken.
