*Sweet bean paste : A number of pastes are common fillings found in Chinese desserts. Although red bean paste, made from azuki beans, is the most common worldwide, there are regional and original preferences for bean paste made from Mung bean as well as known throughout history.
*Jujube paste : A sweet paste made from the ripe fruits of the jujube plant. The paste is dark red in colour, a little fruity/smoky in flavour and slightly sour in taste. Depending on the quality of the paste, jujube paste may be confused with red bean paste, which is sometimes used as a filler.

Traditional mooncake vary widely depending on the region where the mooncake is produced. While most regions produce traditional mooncakes with many types of fillings, they usually only make their mooncake from one type of crust or another. Although vegetarian mooncakes may use vegetable oil, many mooncakes use lard in their recipes for a better taste. There are three types of mooncake crust used in Chinese cuisine:
*Chewy: This crust has a reddish-brown tone and glossy sheen. It is the most common type of crust used on -style mooncakes. It is also the most commonly seen type of mooncake in North America and many western countries. Chewy mooncake crusts are made using a combination of thick sugar syrup, lye water, flour, and oil, thus giving this crust its rich taste and a chewy yet tender texture. Chewiness can be increased further by adding maltose syrup to the mixture.
**The dough is also baked into fish or piglet shapes and sold at mooncake bakeries as a chewy snack. They often come individually packaged in small plastic baskets, to symbolize fish being caught or piglets being bound for sale.
*Flaky: Flaky crusts are most indicative of Suzhou-style mooncakes. The dough is made by rolling together alternating layers of oily dough and flour that has been in oil. This crust has a very similar texture to the likes of puff pastry.
*Tender: Mooncakes from certain provinces of China and Taiwan are often made to be tender rather than flaky or chewy. The texture of this type of mooncake crust is similar to the likes of the shortcrust pastry used in Western pie crusts or tart shells. Tender crusts are made mainly of a homogenous mix of sugar, oil, flour, and water. This type of crust is also commonly used in other type of Chinese pastries, such as the egg tart.
There are many regional variants of the mooncake. Types of traditional mooncakes include:

Modern mooncakes differ mainly from traditional types most vividly in the type of fillings that are offered. For instance, mooncakes containing taro paste and pineapple, which were considered novelty items at their time of invention have in recent years become commonplace items. In addition, ingredients such as coffee, chocolate, nuts , fruits , vegetables , ham, and even lychees have been added to give a modern twist to the traditional recipes.
Snowy mooncakes first appeared on the market in the early 1980's. These non-baked, chilled mooncakes were initially filled with traditional fillings such as lotus seed, red bean, or mung bean paste. However, the launch of a truffle snow-skin mooncake in 1994 by Raffles Hotel in Singapore, triggered a wave of modern mooncakes. H?agen-Dazs quickly followed on from this innovation, and were one of the first to create an ice-cream mooncake, with a choice of either the "traditional," snow-skin, or white, milk, and dark chocolate crusts. Moon Cakes have lately become Americanized very much in the United States. Instead of a filling of egg yolk, you can have them filled with marshmallows or chocolate.
Following this bit of lateral thinking, it was obvious these non-baked mooncakes could be filled with pretty much anything that could be made into a paste. An explosion of new flavours appeared and spanned the range from:
* cream cheese
* green tea
* ice cream
White kidney bean paste or plain ice-cream are usually used as a base of flavours such as green tea, coffee, or ginseng, which are not thick enough or cannot be usually in large enough quantities to be a filling on their own.
Modern varieties of mooncakes are also different from their traditional counterparts in that their crusts typically do not require baking. However, they require refrigerating. There are two main varieties of modern mooncake crusts:
*Glutinous rice: A crust with texture similar to that of a mochi. These moon cakes are know colloquially as "''snow-skin mooncakes''" or "''ice-skin mooncakes''" .
*Jelly: A crust made of gelling mixtures such as agar, gelatin, or konjac and flavoured with a wide variety of fruit flavourings.
To adapt to today’s health-conscious lifestyle, many bakeries offer miniature mooncakes and fat-free mooncakes. Some are made of yogurt, , and fat-free ice-cream. Even high-fibre low-sugar mooncakes have made their appearance. To be competitive, bakers boast about how little sugar and oil they use in their mooncakes. Customers can pick and choose the size and filling that suits their taste and diet. For added hygiene, each cake is often wrapped in airtight plastic, accompanied by a tiny food preserver packet. The new version is well-accepted among young people in China.

Mooncakes were used as a medium by the revolutionaries in their espionage effort to secretly distribute letters in order to overthrow the rulers of China in the Yuan dynasty. The idea is said to be conceived by Zhu Yuanzhang and his advisor , who circulated a rumor that a deadly plague was spreading and the only way to prevent it was to eat the special mooncakes. This prompted the quick distribution of the mooncakes, which were used to hide a secret message coordinating the Han Chinese revolt on the 15th day of the eighth lunar month.
Another method of hiding the message was printed in the surface of mooncakes as a simple puzzle or mosaic. In order to read the encrypted message, each of the 4 mooncakes packaged together must be cut into 4 parts each. The 16 pieces of mooncake, must then be pieced together in such a fashion that the secret messages can be read. The pieces of mooncake are then eaten to destroy the message.
