How to Make It
Preheat oven to 425°. Cut puff pastry into 4 equal squares and place on a rimmed baking sheet lined with parchment.
Peel, quarter, and thinly slice apple. In a bowl, sprinkle apple with sugars and cinnamon, tossing to coat, then add cherries.
Place an equal amount of apple mixture in center of each square of dough. Pull 1 corner of dough over mixture to meet opposite corner and form a triangle, then press to seal the 2 corners together, leaving sides open. Bake until golden brown, about 15 minutes.
