Mrs Sabin's Kiddie Tarts

Preheat oven to 375°F (190°C). Open crescent rolls and flatten on a floured surface. Sprinkle half of the dough pieces with 1 teaspoon brown sugar each. Place 1 teaspoon of the butter in the center of each and cover with 1 tablespoon apple pie filling. Sprinkle with another 1/2 teaspoon brown sugar and 1/4 teaspoon of the cinnamon. Place a second piece of dough on top of each tart and press edges together. Brush each tart with 1 teaspoon melted butter. Bake for 12 to 15 minutes or until golden brown.
