I have been tasked with making my father's 65th birthday cake, and he has requested German Chocolate Cake. I have seen a Rose Levy Berenbaum version, an Inside-out Epicurous recipe that gets a lot of good reviews, and a Davide Leibovitz recipe (though it has rum which I hate). Does anyone have any suggestions as to which one to try, or another one instead? He doesn't like things to be overly sweet, so the cake part of the recipe can't be too sweet, especially since I want it to contrast with the sweeter coconut topping/filling. Thanks!
