These dessert bars are just like apple pie, but in bar form. Frosted apple bars have a rich, buttery crust with a sweet cinnamon apple filling and a powdered sugar frosting on top.
In a large mixing bowl, combine the 2 1/2 cups all-purpose flour and 1/2 teaspoon salt. Cut in the 1 cup shortening until crumbly.
Add in the 1 large egg yolk and 2/3 cup milk; dough will be soft.
Divide dough in 1/2 and roll out into two 10” x 15 “ rectangles between two sheets of parchment or waxed paper. Press one half into the bottom and partway up the sides of an uncreased 10"x”15” jelly roll pan.
In a medium sized mixing bowl, stir together the 6 cups thinly sliced apples, 1/2 cup granulated sugar , 1 Tablespoon fresh lemon juice and 2 teaspoons ground cinnamon. Spread evenly over bottom crust.
Place the remaining dough on top of the apples and press the dough on the sides into the bottom dough to seal. Cut several slits in the top dough using a sharp knife.
Bake at 350℉ for 55-60 minutes, or until dough is golden and apples are bubbly. Cool pan on wire rack.
Once cool, combine the 2 cups powdered sugar and 3 Tablespoons water and spread on the top crust. Once set, cut into bars.
