But without solid chocolate bars used to fill them, I substituted with faux  Nutella for what was basically a krantz (aka babka). The activity of this dough was a stunner.  I rolled it up jelly roll style, then cut and braided, loaded it into paper molds and baked…Vavoom, here's what I got with a cup of coffee.
