  • 1 c (2 sticks, 226g) unsalted butter, room temperature
  • 3/4 c (150g) packed dark-brown sugar
  • 3/4 c (150g) granulated sugar
  • 4 large egg yolks room temperature
  • 1 tsp. pure vanilla extract
  • 2 1/4 c (281g) all-purpose flour plus more for work surface
  • 3/4 tsp. baking soda
  • 3/4 tsp. fine sea salt or table salt

  1. In a large bowl, cream together butter and both sugars on medium-high speed until light and fluffy, about 3 minutes.

  3. With hand-held mixer off, add in vanilla. Set aside.
  4. In a large bowl, whisk together flour, baking soda, and salt.
  5. With the mixer on low, add flour mixture to butter mixture; mix until just combined. Scrape down sides of bowl and mix to combine.
  6. Divide dough into three equal portions. Wrap each portion with plastic wrap and transfer to refrigerator; let chill for 30 minutes. Meanwhile, coarsely chop chocolate into thin shards. Set aside.
  7. Unwrap each portion of chilled dough and place on a lightly floured work surface. Roll approximately 1/2 inch thick.

  8. Sprinkle with half the chocolate and top of a second portion of chilled dough. Sprinkle with remaining chocolate and top with remaining portion of dough. Gently flatten with rolling pin.
  9. Prepare a 7-inch cast iron skillet with baking spray. Carefully move cookie down to skillet.
