Step 1

To prepare pastry, in a large mixing bowl, combine flour, sugar, salt and shortening and mix to form a stiff dough.

Step 2

Place egg yolk in a measuring cup; add enough milk to equal 2/3 cup and blend. Stir into pastry mixture. Divide dough in half; roll out one piece into a rectangle to fit a cookie sheet or jelly roll pan. Sprinkle dough with corn flakes.

Step 3

Core and peel apples, and then slice them. Place the apples on top of the corn flakes.

Step 4

In a small bowl, mix sugar, cinnamon and flour; sprinkle over apples.

Step 5

Roll out remaining pastry and place over apples; pinch edges together. Beat egg white until stiff; spread over top crust.

Step 6

Bake at 375° F for 1 hour.

Step 7

To prepare glaze, in a small bowl, combine milk and powdered sugar and blend until smooth, thin glaze forms. Drizzle glaze over top of apple bars while still warm. Enjoy!
