All right, this will probably gross some folks out, but, one thing I lke to eat is just straight whole wheat flour mixed with anough water to make a kind of stiff dough. It's basically what you would make a chapati or tortilla with if you use no leavening agent. You can add a little oil to it if you like, whether for flavor or for calories. Actually, I got the idea from the traditional Tibetan staple of tsampa, which is barley flour, mixed with tea that is laced with Yak butter. I simplified it, and not having Barley flour, used whole wheat. I've always loved to eat bread dough and cookie dough, so I like your idea of the muffin mix - kinda like pudding, in a way.
