In a medium bowl, stir together the flour and
salt. Cut in the 1
cup butter until mixture is mealy. With a fork,
stir in the 2/3 cup milk
and egg yolk. Divide dough into 2 equal parts. On
a lightly floured
surface, roll out 1 piece of dough into a large
rectangle. Place on the
bottom of a 9x13 inch baking pan.
Sprinkle cereal over the crust, then layer
the apples over the
cereal. Stir together the 1 cup of white sugar,
and the 1and 1/2
teaspoons of cinnamon and the nutmeg; sprinkle
over the apple layer.
Roll out the other half of the dough and cover
everything in the pan.
Brush top crust with the reserved egg white and
sprinkle with a mixture
of 2 tablespoons sugar, and 1/2 teaspoon of
cinnamon.
Bake for 45 minutes to 1 hour in the preheated
oven. Top crust should
be lightly browned. Mix together the 1 cup of
confectioners sugar, 1 and
1/2 tablespoons of milk, and 1/2 teaspoon of
vanilla until smooth;
drizzle over bars while they are still warm.
