The Cake Mix Doctor by Anne Byrn; photographs by Anthony Loew (NY: Workman Publishing, 1999)
I have been baking from this book for many years and all the cakes (and frostings) have been wonderful. The darned good chocolate cake is a go-to recipe for me and is a hit every time. The red velvet cake (which I have also made in green and in purple) is also fabulous. (Yes, you do need that much food coloring.) Besides a wide variety of basic cakes this book also includes some regional specialties like cola cake, hummingbird cake, and gooey butter cakes.
The only problem I have with these recipes (and it isn't the book's fault) is that the cake mixes Byrn tells you to use are either with or without pudding already added and as "pudding int he mix" is no longer a thing that the cake mix companies are promoting it can be hard to find the correct kind of mix. I have used what I could find at the store (pudding or not) and the cakes have come out fine. If you like cake this is a book to have on your shelf.
