3 ingredient lemon squares

Popsicles may be the ultimate epitome of summer, but anything citrus comes in at a close second.  I was thinking lemons...and easy enough for the kids to do.  Hence the lemon squares. 

All you need are a 13x9 pan, greased, a box of angel food cake, a can of lemon pie filling, and some powdered sugar.

It's so easy even little Johnny thought he should lend a hand.

 How to:

1.  Mix cake mix and lemon filling in a bowl.  Pour into pan. 

2.  Bake at 350 for 20 minutes.

3.  Sprinkle powdered sugar and let cool before serving.
