  • 2 sheets frozen puff pastry, thawed according to package directions
  • 1 cup marshmallow fluff, divided
  • 3 milk chocolate candy bars (1.55 ounces each), divided
  • 1 large egg, beaten


  • 1 tablespoon butter, melted
  • ½ teaspoon cinnamon
  • 1 teaspoon brown sugar
  • 2 teaspoons graham cracker crumbs, approximately ½ sheet


  1. Preheat the oven to 400°F and line a large baking sheet with parchment paper.

  2. Lay puff pastries on a flat surface and cut each sheet into 9 squares, for a total of 18 squares between both sheets.

  3. Place nine puff pastry squares on the lined baking sheet. Reserve the other nine.

  4. Divide the chocolate evenly between the nine squares. I placed three sections from the chocolate bars on each of the nine puff pastry squares. (Reserve the 9 remaining chocolate sections for melting and drizzling later.)

  5. Top with about 2 tablespoons of marshmallow fluff.

  6. Using your finger or a pastry brush, wet the edges of the filled puff pastry squares with water and top with the reserved puff pastry squares. Use a fork to crimp and seal the edges.

  7. Use a pastry brush to brush the beaten egg on the outside edges of the pastry.

  8. Bake for 15- 18 minutes, or until golden.


  1. Meanwhile, in a small bowl, combine cinnamon, sugar, and crushed graham cracker. Set aside.

  2. After the s'mores are done baking, working one at a time, brush the pastry with the melted butter, and then sprinkle the graham cracker mixture on top. (Be sure to work one at a time or the butter will seep into the pastry, resulting in the graham cracker topping not sticking.) Repeat with the remaining pastries.

  3. Finally, melt the remaining pieces of chocolate in a piping bag or zipped plastic bag in the microwave in 15-second increments until liquid.

  4. Cut off the tip of the bag (or corner of the plastic bag) and drizzle the melted chocolate over the pastries. Serve warm.
