Snow Skin Mooncake with Mung Bean Filling by My Kitchen Snippets. Mid autumn celebration is just around the corner and I’ve seen so many bloggers posting mooncakes. I too get excited and eager to try my hand in making Snow skin mooncake or also known as crystal mooncake. Since I still have a packet of cooked glutinous rice flour in my pantry I decided to make some last week. I just love the moulds that Ann helps me to purchase from Singapore. Don’t you think they are very pretty?
