Found this recipe here at Our Best Bites. Made it today to run around to all the people I was supposed to visit teach this month! Loved it! My notes are in bold:
2 c. flour
1/2 c. sugar
1/2 tsp. baking powder
1/2 tsp. salt
1 c. real butter, softened (no substitutions!)
1 egg, beaten
1/2 c. white sugar
1/4 c. flour
1 tsp. cinnamon
4 c. (about 3 medium) sliced, peeled baking apples (I used 4 small Gala apples)
2 c. powdered sugar
About 3 Tbsp. milk
1 tsp. almond extract (I used vanilla)
To prepare crust, mix flour, sugar, salt, and baking powder in a medium bowl. Cut in butter with a pastry blender or two knives until you have pea-sized crumbles. Gently mix in beaten egg.
Spray a 9x13 baking dish with non-stick cooking spray. Gently pat about 2/3 of the crumb mixture onto the bottom of the dish. Preheat oven to 350 and set aside.To prepare apple filling, combine flour, sugar, and cinnamon and toss with apples. Spread apples out on prepared crust. Sprinkle reserved crust mixture over apples evenly and bake in preheated oven for 40 minutes.When finished, allow to cool completely.
To prepare glaze, whisk together powdered sugar, almond extract, and enough milk to achieve desired consistency. Drizzle glaze over cooled pastry and allow to harden (you can place it in the freezer to hurry things along). Cut into bars and serve.
These really are so good!
