Directions

1. Cut each sheet of puff pastry into six equal pieces. Roll each one out slightly to create a 3x3-inch square.
2. Break each graham cracker into 4 pieces and each chocolate bar into 4 pieces as well. Using one piece of puff pastry at a time: lay a graham cracker piece on one half of the pastry.
3. Add a tablespoon of peanut butter.
4. Add a piece of chocolate.
5. Add 3 to 4 mini marshmallows.
6. Wet the edges of the pastry with water so it will stick together.
7. Fold the top half of the pastry over the other ingredients and use a fork to press the edges together and seal the ingredients inside.
8. Carefully place each pastry on a parchment-lined baking sheet.
9. Crack the egg into a small bowl and add a tablespoon of water; whisk the egg and water together. This creates the egg wash for the pastry.
10. Brush the egg wash on each pastry (make sure that you brush along the edges, too).
11. Bake in a 400-degree oven for 12 to 15 minutes or until the pastries are golden brown.
12. Melt the butter in a small saucepan and add 1 cup of mini marshmallows. Heat and stir until the marshmallows are completely melted. Place the marshmallows in a pastry bag and pipe in a zig-zag pattern over the top of the pastries. Place the mini chocolate chips in the marshmallow piping.
