Preheat the grill to medium heat.

Get two 12- inch pieces of aluminum foil and brush the center with some of the melted butter.

Then brush all sides of the shortcakes with butter and place 3 cakes on each 12-inch square of aluminum foil . Place two of the 12 pieces of chocolate into the well of each shortcake shell.

Crushed a piece of graham cracker over each cake. Top each with mini marshmallows.

Place the prepared foil sheets topped with the cakes on the grill . Close the cover and cook until the marshmallows are browned and toasted, about 5 minutes.

Remove from the grill, place on a plate and drizzle with the chocolate sauce.
