01 - Preheat your oven to 375°F. Line a baking sheet with parchment paper.
02 - Unroll the crescent dough and separate it into 8 triangles along the perforated lines.
03 - Place one piece of chocolate and one marshmallow at the wide end of each dough triangle.
04 - Roll up each triangle starting from the wide end, wrapping the filling inside. Pinch the edges tightly to seal.
05 - Place the rolled dough seam-side down on the prepared baking sheet, spacing them evenly.
06 - Brush the tops lightly with melted butter if using, then sprinkle crushed graham crackers evenly over all rolls.
07 - Bake for 10 to 12 minutes until the rolls are golden brown and cooked through.
08 - Let the rolls cool for 3 to 5 minutes before serving—the chocolate and marshmallow filling will be very hot.
