Prep: Turn on your oven broiler and make sure it is set to high. Line a baking sheet with a piece of parchment paper.
Separate the Oreos from each other and place half of them on a large baking sheet (with the cream side facing up).
Cut the marshmallows in half and place one half on each of the cookies on the baking sheet.
Top each marshmallow with two squares of Hershey chocolate and top with the remaining cookies.
Bake: Place the baking sheet in the oven and allow the s’mores to cook for about 5 minutes, or until the marshmallow begin to brown.
Remove the baking sheet from the oven and use a spatula to transfer the s’mores to a cooling rack. Allow the s’mores to cool for about 10 minutes. Serve and enjoy!
