Directions:

Preheat oven to 350°. Spray a 9"x 13" baking pan with nonstick spray. Mix the cake mix and the lemon pie filling by hand, just until the cake mix is all moistened. DO NOT use an electric mixer on this. If you use an electric mixer or over beat this, it will put too much air in it and it will rise up and out of your pan and you will have a mess. It works perfect if you just stir it by hand until it's all moist. You will notice that is gets sort of bubbly and that is normal.

Spread evenly in the baking dish and place on the center rack in your oven for approximately 25 minutes. It will just be starting to brown on the edges. Don't let it brown on the top. The full 25 minutes are usually needed.

Remove and allow to cool. Sprinkle with powdered sugar and cut in squares.
