If you are wanting to try cake mixes then I would suggest mixing one can of pop with the mix. Clear soda if it is a white cake mix like Vanilla and pepsi with chocolate cake mix. I've never heard of water alone though. The pop is in substitue of eggs, oil and water.
i know there are sevral water only mixes you buy in bulk fro sysco or other food services, they are TERRIBLE. no amount of doctoring give these a good taste or texture. and they get hard super fast, i am talking rock hard . we use the water only bases to do display cakes that are carved that we have trouble making out of foam. HTH
I have some that I get from my local supplier. It only asks for water and oil. I use it when I want to create dummy cakes or practice stuff for sculpting. I know Dawn make some, but I've been working through a 50 lb bag for so long, I can't recall the manufacturer!
I got two free Just Add Water mix at a food show in May. It was HORRIBLE. Dry and crumby. It had no taste. I doctored the 2nd one and it was a waste of pudding and sour cream. Yuck. My advice is to stick to the traditional mixes.
