Mix flour, baking soda, cold butter, spices, sugar and yogurt and form a dough. Put the dough in a large square oven dish. Bake 30 minutes at 200 degrees Celsius. In the meantime, cut and build a house from cardboard paper and use it as an example. Allow the biscuit to cool down but not completely, it should still be soft. Cut with the help of the cardboard 2 roof plates, 4 walls and a chimney. From one of the walls, cut a door and window. Make a "glue" from powdered sugar and water and glue the parts together. For decoration, glue the M&M's to the house. Put some cotton in the chimney as smoke.

I was inspired by a very big cookie house which was made by the cook of the Intercontinental Hotel Tashkent and on display every year at Christmas. The making of this house is very time consuming. However it is simple and children will love it.

The Worldcook site has also a page for Christmas cookies.

Make a dough from flour, soft butter, egg, sugar and vanilla sugar. Form from these trilobites (they look like ancient cockroaches) with the help of a fork as you like them. Put raisins for eyes. Bake 15 minutes at 180 degrees Celsius. Allow them to cool off during 30 minutes. Melt the chocolate with the cream and dip in the back end of the animals.

When I was looking for some information on trilobites (very interesting subject!) for my son Victor, I came across this recipe on the website of Professor Hart and slightly adapted it. Scary!
