The black-and-white portraits near the bottom of the box are, of course, Betty Crocker, and one of several generals named Mills (You do
realize the Betty Crocker is married to Gen. Mills, right?)
More seriously, it occurs to me that if you're really looking for something "closest to home made," i.e., to what ordinary civilians make for themselves, at home, then you probably do want any mix, and you probably want either canned frosting, or a dense, non-whipped, cold-process, all-butter BC, made from the recipe that's been on the back of the powdered sugar box since before most of us were born. Because most ordinary civilians don't make complex hot-process or meringue-based BCs, or use rolled fondant, or use ganache, or exotic bakery fillings. Oh, and if it's a sheet cake, well, for a true home made look, feel, and taste, it should be served in-pan. Or if it's a layer cake, the cakes should be de-panned, put together bottom-to-bottom, unsplit and unleveled, on an ordinary dinner plate, with the aforementioned cold-process BC as a filling, then frosted with no extraordinary effort made to hide the seam between the two layers, and with the top left proudly domed.
