COMBINE all the ingredients except ko fun in a mixing bowl. Add the ko fun last and mix well. Make into equal portions of 110g balls to be used as filling.
Flour your hands lightly and wrap pastry dough over filling. Seal the edges. Lightly dust the mooncake mould with flour. Place each portion into the mould. Press slightly then level with the flat of your palm. Give the mould five hard knocks to dislodge the mooncake.
Place mooncake on a lightly greased tray and bake in a preheated oven at 180ºC for 10 minutes. Remove mooncake from the oven, leave aside for 2 mins. Brush egg glaze over it and bake at 180ºC for another 8 mins or until golden brown.
