Day 4: S'more Puff Pastry

As requested on Instagram, this is my tutorial on my S'more puff pastry. I know I need a better name, so I'm taking suggestions. Super easy dessert:
Ingredients:
1 Frozen Puff Pastry
Chocolate of your choice
Butter (2-3 TBS)
Marshmallow or Peeps
Egg (for egg wash)
400 Degree oven (Said 425 in the video, sorry) for about 20 minutes until golden brown.
Top it with some powdered sugar.
