Snowskin mooncakes with purple sweet potato and cream cheese filling

Most Chinese festivals revolve around food and Mid-Autumn Festival is no exception . Mooncake is a must during this festival here in Hongkong . Baked mooncake with salted egg yolk filling is still popular as ever but the snowskin version which is similar to mochi  is a much lighter alternative . The crust is made from glutinous rice flour or a combination of flours and should be kept frozen .

In this recipe , I divided the snowskin dough into 3 portions and added matcha powder and purple sweet potato powder and leave one portion as is for flavour and colour variations . The flavour of matcha tastes wonderful so as the sweet potato , the plain snowskin is a great canvas for other flavours . I was planning to add cocoa powder but I already tried it when I made my 2nd batch of snowskin a week ago so I left it out on this 3rd batch .

The crust of this mooncake is a cooked/steamed dough and pretty easy to make . The dough is sticky but easy enough to handle as long as you use plastic gloves , if that's not available , use a plastic wrap to roll each piece . I saw the filling recipe on my Facebook feed weeks ago and decided to try it . I tweaked the recipe a bit , added cream cheese and reduced the oil to half . The filling was so delicious I had to stop myself from eating it all , it tastes a bit like sweet potato ice cream , the added cream cheese is the culprit, I think đŸ˜€
