Baking a chocolate babka is no casual undertaking. This Eastern European favorite is worth every sugarcoated second – with a moist, deeply flavored brioche-like cake wrapped around a dark fudge filling, walnuts, and orange zest…..that’s pretty much the best way we can describe this experience.   Don’t be like Jerry and Elaine in the classic episode of Seinfeld—always go with the chocolate babka!
