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 firmly to seal as much as possible to prevent leakage during baking.
05 - Place the filled rolls seam-side down on the prepared baking sheet, leaving space between each for expansion.
06 - Brush the tops lightly with melted butter if desired for added richness and to help the graham cracker topping adhere.
07 - Sprinkle the crushed graham crackers evenly over the tops of all rolls, pressing gently to ensure they stick.
08 - Bake for 10 to 12 minutes or until the crescent dough is golden brown and the filling is melted and bubbly.
09 - Let the rolls cool on the baking sheet for 3 to 5 minutes before serving. The chocolate and marshmallow filling will be extremely hot.
