Peel apples and slice in uniform slices approximately 1/4 inch thick. Using a medium size mixing bowl combine sugar, cinnamon, cloves nutmeg.
Unroll the pie crust and place on a 9"x13" baking pan or cookie sheet. Using a knife cut the pie crust to fit the pan.
Use the cut pieces of pie crust to fill in any empty voids on the cookie/baking sheet.
You can "glue" the pieces together by using a wet finger to lightly wet the crust first and then adding the cut pieces to cover the bottom of your cookie/baking sheet.
Spread the crushed corn flakes over the top of the pie crust and arrange the apples on top of the crushed corn flakes. Next, sprinkle the sugar mixture over the top of the apples.
Reserve approximately 3 tablespoons of the sugar mixture. This will be used to sprinkle on the top crust prior to baking.
Unroll the 2nd pie crust sheet and repeat the steps above to cover the apple bars.
Whisk the egg and brush over the top of the crust. Sprinkle the remaining sugar mixture over the top of crust. Bake for 50 to 60 minutes or until golden brown.
For the Glaze
Mix powder sugar, vanilla and milk together. Be careful not to add too much milk. You want the mixture to be smooth and thick enough to drizzle over the top of the bars. You do not want this mixture to be too runny.
The glaze can be drizzled over the bars after they have been removed from the oven and cooled for approximately 20 minutes.
Allow the glaze to set before servicing. Bars can be served slightly warm or completely cooled.
