Preheat your oven to 375 F.
Open up the croissant dinner rolls (store-bought), and add in the crushed graham crackers, chocolate chips, and one marshmallow.
Securely wrap all the ingredients with the croissant dinner rolls, especially the edges to prevent the ingredients from oozing out.
Place all the assembled croissant dinner rolls on a baking sheet lined with parchment paper.
Bake for about 12-15 minutes.
Drizzle with your desired amount of hot fudge sauce and top with graham crackers and chocolate chips.
