Mix first four ingredients together. Add a little water if necessary to form a dough. Chill for 2 hours before use. After chilling, roll out to 1/16 inch and press into well-greased 10-inch tart pan. Set aside any extra pastry for later use. Mix the remaining dry ingredients well. Add apples, mix well, and spoon into pastry-lined tart pans. With any remaining pastry, cut out shapes and layer over tarts. Sprinkle with a little more cinnamon and brown sugar if desired. Bake at 350 degrees until light brown, about 40 to 45 minutes.
