Cinnamon Apple Pie Bars

Step 1
Preheat oven to 375 degrees F (190 degrees C).

Step 2
Roll 1 pie crust pastry onto a work surface; lightly roll with a rolling pin until crust is a 9×13-inch rectangle, cutting crust if needed. Press crust into the bottom of a 9×13-inch baking dish, placing leftover crust pieces in the corners.

Step 3
Whisk white sugar, flour, cinnamon, and nutmeg together in a large bowl. Toss Granny Smith apples and gala apples in sugar mixture until evenly coated. Spread apple mixture evenly over pie crust; pour remaining juices over apples.

Step 4
Roll the remaining pie crust to 9×13-inch rectangle and place over apple layer, folding edges over apples to completely cover.

Step 5
Bake in the preheated oven until crust is lightly browned, 45 to 50 minutes. Cool apple bars slightly, about 20 minutes.

Step 6
Whisk confectioners' sugar, milk, and vanilla extract together in a bowl until topping is smooth and desired consistency; drizzle over bars.
