2 cup flour
200 g (or 0.5 lb) butter or margarine
3 tbsp sugar powder
1 egg white
1 pinch vanilla sugar
Warm the butter to 21 C (70 F), blend it a little, add all the other ingredients, and knead for about 5 minutes.
Then, place the dough in a confectionary bag, and make various shapes on a baking sheet.
Pre-heat an oven to 200-230 C (392-436 F), and bake the cookies for 10-15 minutes.
(Do not overcook!)
