Ingredients

Scale
  • 1 cup (225g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 1 cup (220g) packed light brown sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 2 ½ cups (315g) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ½ teaspoon peppermint extract (optional)
  • 1 cup (175g) semi-sweet chocolate chips
  • ½ cup (90g) milk chocolate chips
  • Green sanding sugar or sprinkles for garnish (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease your 10-12 inch cast iron skillet with butter or non-stick spray.
  2. In a large bowl, beat 1 cup softened unsalted butter with 1 cup granulated sugar and 1 cup light brown sugar until fluffy and pale, about 3-4 minutes using an electric mixer or vigorous whisking.
  3. Beat in 2 large eggs, one at a time, then stir in 1 teaspoon vanilla extract and ½ teaspoon peppermint extract.
  4. In a medium bowl, whisk together 2 ½ cups all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt.
  5. Gradually fold the dry ingredients into the wet mixture using a rubber spatula until just combined.
  6. Fold in 1 cup semi-sweet and ½ cup milk chocolate chips, saving a handful to sprinkle on top.
  7. Spread batter evenly in the skillet. Sprinkle reserved chocolate chips on top and lightly press them into the batter.
  8. Use a butter knife or skewer to gently swirl the chocolate chips on top.
  9. Bake for 25-30 minutes, starting to check at 22 minutes. Bars should be golden around edges but still slightly soft in the center.
  10. Let the skillet bars cool in the pan for 15 minutes before slicing.
  11. Sprinkle with green sanding sugar or sprinkles if desired, then cut into squares and serve.

Notes

Rotate the skillet halfway through baking if bars bake unevenly. Use room temperature eggs and softened butter for best texture. Swirl chocolate chips on top to maintain gooey pockets. Prepare batter ahead and refrigerate up to 24 hours, bring to room temperature before baking. Let bars cool 15 minutes before slicing to keep chocolate gooey.
