Aunt Beeb's Chess Bars

I had never eaten a chess bar until I married my husband. His aunt's chess bars are a holiday tradition. I've never made them and I'm not sure why since they are so out of this world tasty. Yesterday, one of my co-workers was lamenting that she wanted to make these for a Halloween party but could not find her recipe. Luckily, I had Aunt Beeb's so I was able to hook her up. And she's almost 100% sure this one is the same as hers. I guess great cooks cook alike!
