I know you probably already have what you are looking for, but try this! My mom used to make the kind of frosting you are describing, and I can make it - but it is a pain. I stumbled across 2 different recipes last year that are easy to do, and mimic the recipe perfectly (I even fooled my oldest brother - who had a passion for mom's version). I'm not sure if I can put them in here because of copy write protection, but here is how to find them: Pillsbury.com - search for Chocolate Cherry Bars - the frosting is divine! (I double it for a 9x13) in Google type in "grandma pearl's flaky chocolate icing southern plate" and you will find the recipe ( this is the one that fooled my brother, but the Pillsbury one is easier to make). The Southern Plate Cookbook is definitely worth buying - she has many recipes that are reminiscent of old recipes (try the Old Fashioned Peanut Butter Icing - version of the Flaky Chocolate Icing - yum!) Happy cooking!
