1 sheet (1/2 package) puff pastry
2/3 cup brown sugar
1 teaspoon cinnamon
1 teaspoon corn starch
2 large apples
1 tablespoon lemon juice
1/4 cup powdered sugar (optional)
Thaw 1 sheet of puff pastry (1/2 package) according to package directions. Preheat oven to 400 degrees F. On a lightly floured work surface, unfold one sheet of pastry. Cut the pastry in half, creating two rectangles. Place the dough on a baking sheet lined with parchment paper, or a baking sheet sprayed lightly with cooking spray. In a small bowl, combine brown sugar, cinnamon, and corn starch. Prepare apples by peeling and removing the core, then slice apples thinly.
Put apple slices in a bowl and toss with lemon juice. Then, add the cinnamon/sugar mixture to the apples. Stir to coat. Arrange apple slices on both pieces of puff pastry dough like shingles, leaving about 1/4 inch of dough exposed on all sides. Bake tarts in preheated oven for 20 minutes. Sprinkle with sifted powdered sugar, as desired. Enjoy warm, or at room temperature. Serve with fresh whipped cream, or vanilla ice cream. Makes 2 tarts.
