Ingredients:

  • 113g Unsalted butter
  • 100g Dark brown sugar
  • 65g Granulated sugar
  • 1 Large egg
  • 5ml Pure vanilla extract
  • 140g All purpose flour
  • 1/2 tsp Baking soda
  • 1/2 tsp Flaky sea salt
  • 170g Semi sweet chocolate chips

Instructions:

  1. Heat the oven. Set your temperature to 180°C (350°F) and place your rack in the middle position.
  2. In your 25cm skillet over low heat, melt the 113g of butter until completely liquid but not bubbling.
  3. Pour the melted butter into a large bowl and whisk in the 100g dark brown sugar and 65g granulated sugar until the mixture looks like wet sand.
  4. Whisk in the egg and 5ml vanilla extract until the mixture becomes glossy and smooth.
  5. In a separate small bowl, stir together the 140g flour, 1/2 tsp baking soda, and 1/2 tsp sea salt.
  6. Gradually stir the dry ingredients into the wet mixture until just a few streaks of flour remain.
  7. Gently stir in 170g of chocolate chips.
  8. Wipe your skillet clean (it should still have a light coating of butter) and press the dough evenly into the bottom.
  9. Place in the oven for 18-20 minutes until the edges are golden brown and starting to pull away from the sides.
  10. Remove from the oven and let it sit in the skillet for at least 10 minutes. The center will firm up as it cools.
