Sydney cake went viral in China after train chat

A Sydney patisserie's chocolate mousse cake went viral on Chinese social media after a chance train encounter, causing demand to surge from 100 to 150 cakes daily. The unexpected popularity has led to the cake being nicknamed "old baby cake." The viral fame stemmed from a vlogger's conversation with a local woman, Margie, who raved about the cake. The vlogger's video showcasing the cake and Margie's endorsement resonated with viewers, driving them to the patisserie. The patisserie owner has temporarily stopped making the cake to focus on regular customers, but the experience has highlighted the power of human connection and cultural exchange. The vlogger and the woman have formed a friendship.
