Ingredients:

  • 2 cups (240g) all-purpose flour
  • 1 tsp (5g) baking soda
  • 1/2 tsp (2.5g) salt
  • 3/4 cup (170g) unsalted butter, softened
  • 1 cup (200g) brown sugar, packed
  • 1/2 cup (100g) granulated sugar
  • 1 large egg
  • 1 tsp (5ml) vanilla extract
  • 1 cup (150g) mini marshmallows
  • 1 cup (150g) chocolate chips (semi-sweet preferred)
  • 1/2 cup (50g) graham cracker crumbs

Instructions:

  1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
  2. In a bowl, whisk together flour, baking soda, and salt. Set aside.
  3. In a separate bowl, cream together softened butter, brown sugar, and granulated sugar until light and fluffy.
  4. Add the egg and vanilla extract, mixing until well combined.
  5. Gradually add the dry ingredients to the wet ingredients, mixing just until incorporated.
  6. Fold in mini marshmallows, chocolate chips, and graham cracker crumbs.
  7. If the dough is too soft, chill in the refrigerator for about 15 minutes.
  8. Scoop the dough onto the prepared baking sheet, forming a large cookie shape or press it into a single large circle, about 1 inch thick.
  9. Bake in the preheated oven for 25-30 minutes or until the edges are golden brown and the center is set but still soft.
  10. Allow to cool for a few minutes on the baking sheet before transferring it to a wire rack to cool completely.
  11. Slice into wedges or squares and serve warm.
