- With the rack in the lowest position, preheat the oven to 400°F (200 °C). Line a baking sheet with parchment paper.
- On a lightly floured surface, roll out the puff pastry into a 10-inch (25 cm) square. With a fork, prick the entire surface of the dough. Place the dough on the baking sheet.
- Spread the cream on the entire surface of the dough. Cover with the apple slices. Sprinkle with the chives and top with the cheese slices.
- Bake for about 20 minutes or until the cheese is golden brown. Let cool. Cut and serve as hors-d’oeuvres or an appetizer.
Substitute the cheddar with the cheese of your choice, to taste.
