Let's not talk about moon cakes after eating them. Wheel cakes are not baked in direct contact with heat, but heated through iron molds. However, their skin is thin, although they are the same as flour.
But it's not as exquisite as moon cakes, and the insides are mostly thick red beans, cream, pickles, etc. Now there are various materials for wheel cakes.
There are many kinds, such as crispy Explosicum, pearls, and even ice cream flavors, but one thing is that the materials used for the fillings are not as expensive as those used in moon cakes.
