Equipment

  • Baking Sheet
  • Parchment Paper
  • Oven with broiler setting
  • Knife (for cutting marshmallows if needed)
  • Spatula or tongs

Ingredients

  • 12 Oreo cookies plus extra if you want a double-cookie sandwich
  • 6 large marshmallows
  • 1 bar Hershey’s Chocolate

Instructions

  • Preheat your oven broiler to low and line a baking sheet with parchment paper.
  • Break the chocolate bar into rectangles along the perforations.
  • Twist the Oreo cookies apart and arrange 6 Oreo cookies halves on the baking sheet.
    A baking sheet lined with parchment paper holds eight chocolate sandwich cookies with cream exposed. Glass bowls contain marshmallows and chocolate squares nearby.
  • Place two rectangles of chocolate on top of each Oreo half and then place a marshmallow over the chocolate.
    A baking sheet lined with parchment paper holds six cookie sandwiches topped with chocolate squares; a bowl of marshmallows and a plate with cookies are nearby.
  • Broil for 1–3 minutes, watching closely, until the marshmallows are puffed and lightly golden.
    Six toasted smores sit on a parchment-lined baking sheet, with a glass bowl containing three marshmallows above them on a white surface.
  • Remove from the oven and immediately top each with another Oreo cookie half, pressing gently to form a sandwich.

  • Let cool for 1–2 minutes before serving so the marshmallow sets slightly and doesn’t ooze out too much when eaten.

Notes

  • Arrange the cookies evenly on the baking sheet for consistent heating.
  • Press the top cookie on gently to avoid squeezing out all the marshmallow.
  • Serve while still slightly warm for the best texture.
  • Have the top cookie halves ready before removing the pan from the oven.
  • Line the baking sheet with parchment paper for easier cleanup.
