Nothing like a basic cookie dough recipe, a rolling pin and some cookie cutters for an hour of quiet fun. This recipe was also useful because it used an egg yolk but no white. And I have plenty of recipes that use egg whites but not the yolks!
100g soft butter
1 egg yolk
225g plain flour
about 2 tbsps of milk
Cream butter and sugar then beat in the egg yolk. Add flour and mix well. Stir in enough milk to make a smooth dough. Roll out thinly on a floured surface and cut out cookie shapes. Lay them on a lined or greased tray and bake at 180 degrees celcius and bake for 10 - 15 minutes or until just golden. Ice when cold if you like. A good bikkie for dipping into a hot drink.
