Cut out centers of each bread slice with a 3-inch round cutter; reserve scraps for another use. Place half of bread rounds on a lightly greased baking sheet.
Stir together cream cheese, apple, powdered sugar, and 1/8 teaspoon cinnamon until blended. Spoon 1 tablespoon apple mixture onto center of each bread round on baking sheet; top with remaining bread rounds. Crimp edges with a fork to seal; brush tops with butter.
Stir together remaining 1/8 teaspoon cinnamon and 2 tablespoons sugar; sprinkle over tops.
Bake at 400° for 8 to 10 minutes or until golden.
NOTE: Store in an airtight container in freezer. To reheat, wrap each pocket in a damp paper towel; microwave at HIGH 1 minute or until thoroughly heated.
