In fact, the cooking cakes sold in Wu Dalang are solid steamed buns instead of sesame cakes. "Water Margin" wrote that when Pan Jinlian had not hooked up with Ximen Qing, Wu Dalang got up early every day to stir up a load of cooked cooking cakes and went out to sell them. Before leaving home, Wu Song once told his brother Wu Dalang: You should stay outside and go home early; Originally, I made ten cages for cooking cakes, and I only need to make five cages in the future. The "fan cage" mentioned here is the steamer. Thus, the cooking cakes sold in Wu Dalang are steamed, so cooking cakes are definitely not baked wheat cakes, but steamed bread.
