I just received this recipe in an email newsletter. This recipe is for a chocolate flavored cookie bar, but it reminds me of a recipe using a cake mix and a similar method that was lemon flavored. So I have not tried this yet, but I expect it to live up to it's title. And I'm hoping to re-create the gooey, tangy lemon bars I used to make from a cake mix with a crumbly topping for after school snacks.
