Place an egg roll wrapper on a clean surface in a diamond shape and place 2 pieces chocolate, about 1 tablespoon of graham crackers crumbs, and 2 marshmallows.
Fold up bottom half and tightly fold in sides. Gently roll, then seal fold with a couple drops of water. Repeat until all egg roll wrappers are used.
In a large skillet over medium heat, heat oil (it should reach 1″ up the side of pan) until it starts to bubble. Add egg rolls and fry until golden, 1 minute per side. Transfer to a paper towel-lined plate and season with cinnamon sugar immediately.
Serve with melted chocolate, if using.
