Crush the nuts to small pieces. You can use food processor or chop them yourself.
Preheat the oven to 400 F.
Measure 30g filling and 20g dough.
Gently flatten the dough, and wrap the filling in. This process is challenging because both the filling and the dough are very crumbly. First you need to squeeze the filling very hard to shape it to a ball. When you wrap the filling, it’s more like slowly pushing the dough slowly to cover filling.
Use the small moon cake mould to shape the cakes.
Bake the moon cakes under 400F for 5 minutes. Brush a thin layer of egg on the surface.
Turn the heat down to 350F, bake another 16-18 minutes until the surface turns to golden brown.
