Ingredients:

  • ½ cup (113g) unsalted butter, melted
  • ½ cup (100g) granulated sugar
  • ½ cup (110g) packed light brown sugar
  • 1 large egg
  • 2 teaspoons vanilla extract
  • 1 ¼ cups (156g) all-purpose flour
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • 1 cup (170g) semi-sweet chocolate chunks

Instructions:

  1. Preheat oven to 350°F (175°C). Grease the skillet well.
  2. Melt the butter in a microwave-safe bowl (or in a saucepan on the stovetop).
  3. In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until well combined.
  4. Beat in the egg and vanilla extract until smooth.
  5. In a separate bowl, whisk together the flour, baking soda, and salt.
  6. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
  7. Gently fold in the chocolate chunks.
  8. Cover the dough and chill in the refrigerator for at least 10 minutes. This helps prevent excessive spreading. (Optional)
  9. Press the cookie dough evenly into the prepared skillet.
  10. Bake for 25-30 minutes, or until the edges are golden brown and the center is just set.
  11. Let the skillet cookie cool in the skillet for about 10 minutes before slicing and serving.
  12. Serve warm, topped with vanilla ice cream, chocolate sauce, and a sprinkle of sea salt (if desired).
