So maybe it's not the production method you working industrial designers have been searching for, but at some point you must have asked yourself: How do they get those printed-looking colored patterns onto individual pieces of chocolate? And how the hell do they get those delicious nuts and gross, creamy jellies into the center of a piece of chocolate that has no parting line on the equator?

Trusty Core77 is here with the answer, friends. And the answer is edible transfer sheets, polycarbonate molds, magnets and a heat gun. First let's look at how they transfer printed patterns onto chocolate:

If it wasn't obvious from the video, the shiny metal sheet he slides the edible transfer sheet onto in the beginning is magnetic. There are magnets embedded in the polycarbonate mold, which holds it fast to the sheet; thus none of the viscous chocolate leaks out while it's "accepting" the colored imprint.

As for how they get stuff into the middle of individual chocolate pieces, this next video starts out using the same pattern trick, then reveals the molding technique:

I started to type "If only plastic could be made to behave that way," but then I realized no client has ever asked a designer to get that disgusting creamy jelly inside an injection-molded part.
