When you are making this, it's easier to work on cardboard. Soak the chocolate writing pens in hot water to soften.
Arrange 5 pieces of wafers for the floor, and glue with the chocolate pen. Stand 4 wafers up on each side of the floor. Glue with the pen one by one.
When all the walls are up, arrange the wafers for the roof. Place them so that the roof extends out past the walls a bit, then glue to secure.
Lay the cigarette russe on the roof one by one. Alternately use one large one, then two small ones. Glue them well to secure.
Stick the door and put the windows on the other 3 walls. Let it sit in somewhere cool or in the fridge to harden.
Transfer to a decorative plate, sprinkle on powdered sugar for snow, and it's done!
If you use different sweets, you can make many different versions of it, so try it out. Make sure you glue the cookies well!! When you want to keep it, wrap it with plastic wrap all over, then it will last for about 3 days.
