1 pkg. (17 1/4 oz.) frozen puff pastry sheets (2 sheets thawed)
4 golden delicious apples (about 4 oz. each) peeled, cored, thinly sliced
4 tbsp. sugar
2 tbsp. unsalted butter (1/4 stick)
Creme fraiche or vanilla ice cream, optional

Preheat oven to 425 degrees. Roll 1 pastry sheet out on floured work surface to thickness of 1/4 to 1/8 inch. Cut out two 6 inch rounds. Repeat rolling and cutting with second sheet, forming 4 round total.

Place rounds on heavy large cookie sheet, spacing apart. Using 1 apple per tart, overlap apple slices atop pastries in circles, forming flower design. Sprinkle each with 1 tablespoon sugar. Dot each with 1/2 tablespoon butter. Bake tarts until apples are tender and pastries golden brown, 25 minutes. Transfer to plates. Serve warm with ice cream or creme fraiche.
