All you need is an angel food cake mix and a can of lemon pie filling. Mix them together and bake in a 9x13 cake pan at 350 degrees for 20 minutes. As they are cooling, you can sprinkle with powder sugar if you wish......the recipe here don't mention to "mix the angelfood cake" according to the directions......you have to do that....I think. Mine's cooking, but there was no way it would've cooked and been any kind of cake or bar if not for the water being added.
Need to try - I've been missing lemon bars in my life... "Melt in Your Mouth Lemon Bars- STOP!!! don't pass this recipe by, lemon lover or not these bars are SO melt in your mouth you'll want to eat the whole pan. Everyone loves them! Blue ribbon winner."
