How To Bake Preheat oven to 400 degrees. In a small bowl, stir together the graham cracker crumbs and sugar. Brush the tops of the frozen biscuits with the melted butter then add a tablespoon spoonful of the graham cracker sugar mixture on top. Bake the biscuits according to package specifications. Remove from oven and let them cool slightly. To assemble, split open the warm biscuits and place a piece of chocolate on the bottom half of each biscuit. Skewer each marshmallow and toast with a kitchen torch or on your stove-top if you have a gas burner. Place 1-2 toasted marshmallows on top of the chocolate and sandwich with the biscuit tops. Serve immediately and enjoy! Note: If you don’t have a gas burner or torch, you can place the marshmallows on the chocolate and place under the broiler until they’re toasted.
