In the 80s of the last century, the young Ma Wenwen followed his father to sell retort cakes all over Xi'an. By 1990, when his father was ill, Ma Wenwen took over the business of retort cakes and set up a stall at the intersection of Sajinqiao Road and Lianhu Road. Around 2017, the stall attracted widespread attention from online media and became famous. The retort cakes here are rich in ingredients and have a sweet taste, which is suitable for first-time diners. The full jujube paste is wrapped with kidney beans, candied dates and other small ingredients, and the taste is obvious. Glutinous rice is steamed until soft, sticky and chewy, but it is easy to get greasy if you eat too much, so it is recommended to prepare a drink to moisten your mouth.

There is no secret to the success of Fat Man Retort Cake, but the long-term persistence and hands-on efforts of the stall owners, even if they are simple to make, have been well received by a large number of diners. At present, the business of Fat Dump Cake is booming, and there is an endless stream of diners who have made a special trip to visit, but the stall owner has not yet expanded his business, and only sells one bucket of Dump Cake every day, which is sold out and no longer replenished, at 5 yuan per serving. The stall time is roughly between 6:00 and 8:00 in the morning, so be sure to eat early.
