If you look at my guides..guilty. I have a slight affection for s'mores
Thaw out two sheets of puff pastry. Cut along the folds to make three long strips
Cut the three strips into halves to make six rectangles
Layer on one half of the pastry: graham cracker
Spoon full of homemade marshmallow cream (from my s'mores bars) or use store bought. You can also replace the marshmallow cream with peanut butter. Then you have peanut butter s'mores.
Lightly wet your finger tips and wet the edges. Then fold over
Use a fork and press all around. Make sure it's stamped shut
Do all 12 and place on a parchment paper lined baking sheet (or use a silpat) and brush with egg wash. Which is a beaten egg with water.
Take a knife and slit tops. The steam need to get out otherwise they might burst while baking.
400, about 15 minutes
They look wonderful just like this but you could warm up a little icing and top
When I make the peanut butter kind, I warm a little marshmallow cream and place in a baggie. Snip the corner and pipe onto tops.
