Ingredients
  

Cookie Dough
  • 1 cup unsalted butter softened
  • 0.75 cup light brown sugar packed
  • 0.5 cup granulated sugar
  • 1 large egg room temperature
  • 1 egg yolk room temperature
  • 2 tsp vanilla extract
  • 2.25 cups all-purpose flour spooned and leveled
  • 1.25 cups graham cracker crumbs finely ground
  • 1 tsp cornstarch
  • 1 tsp baking soda
  • 0.75 tsp salt
Filling and Mix-ins
  • 11 oz milk chocolate chopped into chunks, divided
  • 12 large marshmallows cut in half horizontally
  • 1 pinch flaky sea salt optional, for topping

Equipment

  • Stand Mixer or Hand Mixer
  • Mixing bowls
  • Baking sheets
  • Parchment paper
  • Large cookie scoop
  • Wire rack

Method
 

  1. Whisk together flour, graham cracker crumbs, cornstarch, baking soda, and salt in a medium bowl.
  2. Cream butter, brown sugar, and granulated sugar until light and fluffy (about 2-3 minutes).
  3. Beat in egg, egg yolk, and vanilla extract until just combined.
  4. Gradually mix dry ingredients into wet ingredients on low speed until a soft dough forms.
  5. Fold in about 3/4 of the chopped milk chocolate chunks.
  6. Scoop dough using a large scoop (approx 3 tbsp). Flatten each ball, place a marshmallow half in the center, and seal the dough completely around it.
  7. Chill stuffed dough balls on a baking sheet for at least 1 hour (mandatory).
  8. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
  9. Place chilled balls 3 inches apart on sheets. Press remaining chocolate chunks onto tops.
  10. Bake for 11-13 minutes until edges are golden. Centers will look soft.
  11. Cool on baking sheet for 10 minutes before transferring to a wire rack.

Notes

Chilling the dough is crucial to prevent marshmallows from melting out completely. Total time does not include chilling time.
