Prepare the pastry cream two hours in advance.
Pre-heat oven to 375F / 190C. Line a baking sheet with parchment paper.
Roll out the puff pastry, divide it in half lengthwise. Cover one half with the pastry cream and top with the pitted halved cherries. Place the remaining half pastry on top and seal the edges well.
Brush the top of the pastry with milk. Bake for 35-45 minutes or until golden. Cool to warmish, dust with powdered sugar and serve. Enjoy!
