Preheat oven to 375 degrees.

Roll out pie crust on clean, floured surface. Cut out 8 3-inch circles and gently fit dough into 2 inch flouted tart pans. {Muffin tins will work equally well. Set aside.

In a small bowl, stir frozen tart cherries together with flour, sugar, salt and melted butter. Spoon mixture into pie crusts and cut out mini hearts with remaining scraps of dough. Place stars on top of each mini pie and bake 25-30 minutes or until fruit is bubbly and pie crust has browned lightly.

Cool mini pies 30 minutes before trying to remove from tins. If cherry juices have overflowed, you may want to take a toothpick and run it along the edges of the tart pans to loosen pies while still luke warm. Remove from pans and sprinkle with powdered sugar. Serve.
