I have used a yellow cake recipe that is absolutely gorgeous - half the time. It is an unpredictable recipe, and an extremely inefficient use of ingredients when you're baking large amounts of cake (sometimes it comes out like wet cardboard, other times, it's sticky.) I am a semi-pro baker, and can't seem to find/create a beautiful recipe for a velvety yellow cake. I want a crumb that almost melts in your mouth - velvety is the only word I can think of.
As far as white, I just haven't found the crumb I'm looking for.
If anyone has a recipe for yellow or white cake that is moist, fluffy, velvety, please let me know. I've hit a wall as far as figuring out my own, maybe someone can help to inspire??
