Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.

Microwave butter for 40 seconds until mostly melted, then whisk until smooth.

Stir in granulated and brown sugar. Mix well.

Add vanilla and egg. Stir until combined.

Add flour, baking soda, and salt. Mix until soft dough forms.

Fold in chocolate chips, marshmallows, and graham cracker crumbs.

Scoop dough (about 3 tablespoons per cookie) onto baking sheet, 2 inches apart.

Bake for 10–15 minutes until edges are golden and centers look slightly underbaked.

Cool on baking sheet for a few minutes, then transfer to a wire rack.

Top with extra marshmallows before baking for a gooier finish.

Use dark chocolate chips for a richer taste.

Add chopped pecans or walnuts for crunch.

Drizzle with melted chocolate for presentation.
