Ingredients

  • 1 1/4 cups all purpose flour
  • 1 cup + 1/4 cup graham cracker crumbs
  • 1/2 teaspoon cornstarch
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup butter softened
  • 1/2 cup sugar
  • 1/2 cup light brown sugar
  • 1 egg room temperature
  • 2 teaspoons vanilla
  • 3/4 cup milk chocolate chips
  • 1 cup marshmallow fluff

Instructions

  • Preheat oven to 325º F. Add oil if needed to a 12 inch cast iron skillet
  • In a mixing bowl whisk together the flour, 1 cup of graham cracker crumbs, cornstarch, baking soda, and salt.
  • In a separate mixing bowl combine butter, sugar, brown sugar, egg, and vanilla with an electric mixer until well blended.
  • Gradually add the flour mixture to the butter mixture and mix until a soft dough is formed.
  • Press the dough into the cast iron skillet. Top with the additional graham cracker crumbs and press into the dough before baking.
  • Bake the cookie for 20-25 minutes, until golden on the edges and a toothpick comes out clean from the center of the cookie.
  • Top the warm cookie with the milk chocolate chips and spread across the top of the cookie as they melt.
  • Lastly, drop spoonfuls of marshmallow cream over the top of the cookie and melted chocolate. Place the skillet back into the warm oven for 1 minute, then spread the soft marshmallow fluff over the top. To toast the marshmallow place it under the broiler on the top rack for 1 minute. Don't leave unattended.

Notes

  • Nutrition facts are just an estimate of the ingredients listed. 
  • For the graham cracker crumbs, I prefer to make the crumbs added to the cookie finer and the 1/4 cup placed on top a little more coarse. 
  • Store in an airtight container on the countertop for up to 3 days. Do not store in the cast iron skillet. 
  • to make ahead, bake the graham cracker cookie and add the chocolate and marshmallow before serving, just use the oven to heat and melt the chocolate and marshmallow fluff
