Preheat oven to 400 degrees. Thaw 1 sheet of puff pastry until pliable.
Cut puff pastry sheet in half (lengthwise).
Spread cream cheese on one puff pastry sheet.
Spread blueberry jam on top of cream cheese.
Lay the other puff pastry on top of the blueberry jam/cream cheese mixture so that the mixture is sandwiched between the puff pastry sheets.
Using a sharp knife, cut puff pastry into 6 even strips (cut the long side so you have long strips rather than short strips).
Twist each strip and roll into swirls, making sure to tuck the ends under the swirls so it stays intact while baking.
Brush each with egg wash (one egg beaten with 1 tsp water).
Place on a parchment paper lined baking sheet. Bake at 400 degrees for 25 minutes or until golden brown and pastry is cooked through.
Let cool. Using a sugar duster or mesh strainer, sprinkle each with powdered sugar.
Serve and enjoy!
