Servings 9 Large Cookies


  • 1 stick salted butter softened
  • 1/2 cup light brown sugar packed
  • 1/4 cup sugar
  • 1 egg large
  • 1 tsp vanilla extract pure
  • 1 cup + 3 tbsp flour all purpose
  • 1/2 "heaping" tsp baking soda (or approximately 3/4 tsp)
  • 1/2 tsp salt
  • 1 cup chocolate chips semisweet
  • 7 sheets graham crackers finely crushed
  • 9 marshmallows regular sized


  • Line a cookie sheet pan with parchment paper (or lightly grease your cookie sheet).

Make the dough

  • In a medium bowl beat butter, brown sugar, and sugar with hand held mixer until blended well.
  • Add the egg and vanilla and beat until creamy and fluffy.
  • Add the flour, baking soda, and salt. Mix on low until just combined.
  • Stir in the chocolate chips and graham cracker crumbs.

Assemble the S'mores Cookies

  • Take one marshmallow and mold approximately 1/4 cup cookie dough around it. Place it on a freezer safe plate.
  • Repeat with the rest of the dough and marshmallows.
  • Place the dough balls into the freezer for 10 minutes and then transfer onto a parchment paper lined (or lightly greased) cookie sheet.
  • Meanwhile, preheat the oven to 375 degrees.


  • Bake 9-13 minutes until edges are lightly browned, the top is just starting to brown, and center is still gooey.
  • Take the cookies out of the oven and allow them to sit on the baking sheet to finish baking for at least 10 minutes.


Store in an airtight container for up to 2 days. I suggest heating them up in the microwave for about 15 second before eating. Enjoy!
