  • 12 tablespoons butter softened
  • 1 cup brown sugar
  • 1/2 cup granulated sugar
  • 1 egg
  • 1 egg yolk
  • 1 1/2 teaspoons vanilla extract
  • 1 teaspoon baking soda
  • 2 teaspoons corn starch
  • 1/2 teaspoon salt
  • 2 cups all purpose flour
  • 1 cup graham cracker crumbs
  • 1 cup marshmallow bits
  • 6 regular sized Hershey's Milk Chocolate Bars coarsely chopped, divided use
  • 3/4 cup miniature marshmallows


  • Place the butter, brown sugar and granulated sugar in the bowl of a mixer. Beat until light and fluffy.
  • Add the egg, egg yolk and vanilla to the bowl and beat until well combined.
  • Add the baking soda, corn starch, salt, all purpose flour and graham cracker crumbs to the bowl. Stir on low speed until combined.
  • Add the marshmallow bits and approximately 2/3 of the Hershey bars to the bowl. Beat for 20 seconds or until just combined.
  • Cover the bowl of dough and let it chill for an hour.
  • Preheat the oven to 350 degrees F. Line a sheet pan with parchment paper or a nonstick baking mat. 
  • Roll 1 inch balls of dough and place them 2 inches apart on the prepared pan. You will have to work in batches.
  • Bake for 8-10 minutes or until edges are set. Remove the cookies from the oven and quickly press a few pieces of chocolate and miniature marshmallows into the tops.
  • Repeat with remaining cookie dough. Let cool, then serve, or store in an airtight container for up to 3 days.
