  • 1/2 cup unsalted butter
  • 1 1/2 cups granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 2/3 cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 15 large marshmallows , halved

For the frosting:

  • 1/2 cup butter , softened
  • 2 Tablespoons unsweetened cocoa powder
  • 2 1/2 Tablespoons milk
  • 2 cups powdered sugar
  • 1 teaspoon vanilla extract


  • Preheat oven to 350 degrees. Line a cookie sheet with parchment paper.
  • Add the butter and sugar to a mixing bowl and cream together until light and fluffy, about 3 minutes. Add eggs and vanilla and mix well. 
  • In a separate bowl, combine the flour, cocoa powder, baking soda, and salt. Add to the bowl with the creamed butter mixture and stir just until combined. 
  • Scoop the dough by rounded tablespoons onto your cookie sheet. Bake for 8 minutes. Remove from oven and top with a marshmallow half (cut-size down). Return to oven for 2 minutes. 
  • Allow to cool completely while you make the frosting.

For the frosting:

  • Add butter to a mixing bowl and beat with electric mixers for 1 minute. Add the cocoa powder and milk and mix to combine. Add powdered sugar and mix for at least 2-3 minutes or until smooth. Mix in vanilla. Add more powdered sugar if needed.
  • Once cookies have cooled, cover the tops of the marshmallow and cookie with frosting.
  • Store leftovers in an airtight container, or freeze for later.


My Great-Aunt always added a walnut on top at the end. You could also add crushed peppermint candy, to make them festive for Christmas.
Storing and Freezing Instructions:
Once cookies have cooled completely, store them in an airtight container on the counter for 3-4 days.  To freeze place them in a freezer safe bag or container and freeze for 2-3 months.
