Preheat the oven to 425℉. Line a few baking sheets with parchment paper.
Lightly dust a clean work surface with flour. Add the puff pastry sheets onto the work surface and lightly dust them with flour. Roll each sheet of puff pastry into a square and so that they are slightly thinner than they originally were.
Cut each sheet of puff pastry into 4 squares so you have a total of 8. Pipe 1½ to 2 tablespoons of the cream cheese mixture onto the center of the square, making sure to leave a ½ inch border around it. Spoon 1½ to 2 tablespoons of the cherry filling on top of the cream cheese mixture.
Take one corner of the puff pastry and fold it up and over until it meets the opposite corner, making a triangle. Using your fingers, gently press down on the edges. Then use the tips of a fork to crimp all along the edges to seal the seam. Transfer the turnover onto the lined baking sheet. Repeat this process to make the remaining turnovers. Space then turnovers 1½ inches apart on the baking sheet.
Beat together the egg and milk until combined to create an egg wash. Use a pastry brush to coat the tops of the turnovers with the egg wash. Cut 3 slits onto the tops of all the turnovers so they can vent while baking. Sprinkle the raw sugar onto the tops of the turnovers. Bake them in the over for 23-24 minutes until golden brown. Allow the turnovers to cool for a bit then enjoy!
