Apple Bars

I was going to make Grandma G's Dutch Apple Pie for dessert but was out of Canola Oil. So I made Apple Bars instead which are putzy but delicious!

Mix together like pie crust with a pastry blender or a fork:
2 1/2 cups flour
1 Tbsp. sugar
1 tsp salt
1/2 cup shortening ( I used butter flavored Crisco sticks)
1/2 cup butter
Then add: 1 egg yolk and 2/3 cup milk and stir into a pie crust like mixture. If it's too goopy, add more flour.
Divide the crust into 2 equal parts. Roll out 1/2 of the dough to fit into a jelly roll pan. Cover with 6-8 cups peeled, sliced apples (I used McIntosh) that are mixed with 1 cup sugar and 1 tsp. cinnamon.
Roll out the second 1/2 of the dough and cover the apples.
Bake 40 minutes at 375 degrees.
Frost while hot with a powdered sugar icing. Make with about 3/4 cup powdered sugar and gradually add small amounts of milk until you can drizzle it over the baked crust. That's it! Enjoy!
