I used the recipe posted by Yochana. You can get the recipe here
Actually after baking the mooncakes, you got to wait for a few days for the oil to come out and the skin becomes softer so that the moonies will taste better. But the boys couldn't wait and ate a few of my hello kitty moonies at one go. You can see the cut-up moonies and the pastry is still a little dry as it was freshly baked.
