  • 1/2 cup unsalted butter softened
  • 3/4 cup granulated sugar
  • 1 large egg
  • 1 tsp vanilla extract
  • 1 1/2 cup all purpose flour
  • 1/3 cup cocoa powder
  • 3/4 tsp baking soda
  • 1/2 tsp salt
  • 1 cup chocolate chunks
  • 1/2 cup mini marshmallows


  • Pre-heat oven to 350℉.
  • In a large bowl, cream butter and sugar together, then add egg and vanilla extract. Mix to combine.
  • Add flour, baking soda, cocoa powder and salt. Mix well to combine.
  • Fold in chocolate chunks.
  • Roll dough into 14-16 1.5-inch balls, press 3-4 marshmallows onto the top of each of them, then place them on cookie sheet. Make sure to secure the marshmallow well if not it would fall out during baking.
  • Bake for 9-10 minutes. Check at the 9-minute mark. Once it is done (it will still be slightly soft), let cookies sit on baking sheet for 2-3 minutes before carefully removing them and placing them onto a baking rack to cool for 10 minutes. (See Note 1)
  • Serve and enjoy!


Note 1: Avoid over-baking cookies and also remove them from hot cookie sheet after 2-3 minutes once they are out of the oven so they do not continue cooking. This is to ensure cookies stay soft and moist!
