To add to Ann's post, I have this book too. All recipes use a commercial cake mix as the base of the recipe.
Here is the link http://www.cakemixdoctor.com/books/the-cake-mix-doctor-bakes-gluten-free/
The cookbook author, Ann Byrn, includes her 3 favorites, her kids' 3 favorites and her firends' 3 favorites on the website. Kinda interesting.
Bob's Red Mill site has recipes based on their GF Yellow Cake Mix
http://www.bobsredmill.com/gf-vanilla-cake-mix.html
Under their Recipes tab, a scratch recipe by Carol Fenster is posted as well as many more 'scratch' recipes.
I hope this helps those with the questions.
