These S’mores Cookie Bars deliver all the gooey, nostalgic flavors of classic campfire s’mores in an easy, oven-baked treat. With layers of graham cracker cookie dough, melty Hershey’s chocolate, and creamy marshmallow fluff, they’re the ultimate make-ahead dessert for any occasion.

Ingredients

  • 1/2 cup (1 stick) butter, softened
  • 1/2 cup brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 3/4 cup crushed graham crackers (about 6 full sheets)
  • 3–4 full-size Hershey’s bars (or equivalent in milk chocolate)
  • 1 cup marshmallow crème (aka marshmallow fluff)

Instructions

  1. Cream butter, brown sugar, and granulated sugar in a bowl until light and fluffy. Beat in the egg and vanilla extract.
  2. Add flour, baking soda, salt, and crushed graham crackers. Mix until a soft dough forms.
  3. Divide dough in half. Press one half into a parchment-lined 8×8 or 9×9-inch baking dish. Remove and freeze this layer for the top crust.
  4. Press the remaining dough into the prepared pan. Layer with Hershey’s bars and then spread the marshmallow crème over the chocolate.
  5. Place the frozen dough layer on top as a lid.
  6. Bake at 350°F (175°C) for 25–30 minutes or until golden and set. Cool completely before slicing for clean edges.

Notes

  • Marshmallow fluff creates a smooth, gooey layer that melts better than mini marshmallows.
  • Let bars cool fully before slicing and clean the knife between cuts for neat squares.
  • Mix milk and dark chocolate for added depth of flavor.
  • Bars freeze well—separate with parchment paper before storing.
