I'm a big fan of the cake bible, for a few of my favorite cakes, maybe two or three. The absolutely best perfect all american chocolate butter cake, or the white chocolate whisper cake, and its white chocolate cream cheese buttercream.
I don;t like a lot of the other recipes i;ve tried in it, though. I think i would recommend the book for these two and for some of the ganache recipes and frostings, and for the amazing raspberry reduction and some of the wedding cake construction methods.
Oh, and also, the author will actually help you and give recommendations and advice if you write to her on her blog. She is very knowledgeable and helpful and made it possible for me to make a 6 layer 3 tier chocolate wedding cake with raspberry-chocolate ganache, white chocolate cream cheese buttercream crumb coat and home made fondant frosting, in the 100 degree heat without air conditioning in my kitchen, and transporting to the place outdoors where the wedding was, and it came out amazingly well!
For a beginner (and i don;t know how much of a beginner you are, but i;m not a beginner and continue to use it) i very much like (now don;t kill me here...) the old, 1950 (not later) version of the betty crocker cookbook (a new reedition of the old version has come out, i hate the new version, full of stupid short cuts that don;t really save time but ruin flavor but the re-edition of the old version is the same as the old one and is good.). I have made about 3/4 of the cakes in there and no one has ever (ever!) come out bad. If i want a simple yellow cake, an applesauce cake, gingerbread, spice cake, angelfood cake,sponge cake, etc etc etc, i turn to that. You can;t go wrong. Don;t confuse betty crocker cookbook with cake mixes. It's done with a test kitchen, using different flours, making all the kinds of mistakes peoiple tend to mkae, so the recipes are truly foolproof.
I also have a particular affection for the book by Barbara Maher, called simply "cakes" - it has the best sacher torte, the best dobostorte, the best carrot cake, the best tarte tatin, etc etc, that i ever had. I don;t like her later book "ultimate cakes" - the dobostorte filling is much less interesting, and other things are not as good. But "Cakes" is really worth having. It;s not showy and has no color pictures o0r anything, but is full of great recipes (a particularly great nut cake/bread that you eat with cheese, really unusual things)
