Yes, we have for years. It started very basic and small, and is now a large, artistic creation.
We would never eat the house though, so I can't give you any suggestions for that.
Technically you could eat everything on it, but we use royal icing to bind it which contains raw eggs. Plus, to make the house more sturdy we bake it extra long until it is dry and hard.
It is a lot of fun and a great family tradition for us.
