With some skill that above pictured stock could be duplicated as a popsicle, creamsicle, or fudgesicle using premium quality goods and hand lacing the compoents together as they set up in the mold.
Gawd! Brilliant divine illumination is upon me! That pictured stock looks like a poundcake mix in butterscotch tones with the usual marble lacing. Should be easy to finely execute as a large handmade cookie. And as well a molded butt cake (I think this term could require explanation to someone hearing it the first time) properly toned and laced in with streaking. This is one place where "marblecake" has a double meaning. A "cakestock" could be made in several traditional forms in a clamshell mold. Just the sort of thing for fundraising, gunshows, mail orders, truck stops, etc. Someone with the time should look into this as a hobby commercial endeavor.
