Ingredients

  • 3/4 cup salted butter softened at room temperature
  • 1/4 cup granulated sugar
  • 1/2 cup brown sugar
  • 1 whole egg
  • 1 egg yolk
  • 1 teaspoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 3/4 cup graham cracker crumbs (about 5-6 sheets) plus more for the topping
  • 3/4 cup mini chocolate chips
  • 1 cup mini marshmallows frozen
  • 2 Hershey's chocolate bars cut into mini bars

For the cookie bottoms

  • 6 whole graham cracker sheets cut in half

Instructions

  • Preheat oven to 350 degree F and line baking sheets with parchment paper or silpat mats. Place mini marshmallows on a baking sheet and place in the freezer until frozen, about 10 minutes.
  • Using an electric mixer in a large bowl or in the bowl of a stand mixer, beat together the softened butter, sugars, egg, egg yolk, and vanilla extract. Beat until combined and be sure to scrape the side of the bowl.
  • Add flour, baking soda and baking powder and mix until combined. Add in the graham cracker crumbs and mini chocolate chips. Mix together until all of the ingredients are incorporated and cookie dough has formed.
  • Using a large cookie scoop (or equivalent to 4 tablespoons) to scoop cookie dough. Gently press down to slightly flatten. Add about 1 tablespoon of frozen mini marshmallows in the middle and press the sides to form a dough ball. Make sure the marshmallows are stuffed in to prevent the marshmallows from oozing out. Place each dough ball on a graham cracker square and then onto the prepared cookie sheet.
  • Add Hersheys chocolate bar pieces and graham crackers pieces on top of each cookie. Bake for 10-11 minutes or just until the edges turn a light golden brown. The cookies will be soft, let cool for a few minutes before transferring to a wire cooling rack. Enjoy!
