Put the margarine, sugar, vanilla sugar and the egg in a bowl and stir. Then sift the flour, cornstarch and baking powder, add smaller amounts and stir in.
Finally add the milk so that the dough becomes smoother and of course don`t forget the chocolate sprinkles.
Cut the biscuits with two teaspoons and place them on the baking sheet, leaving enough space as the dough will spread a little while baking. Then bake at 175 degrees for about 10-15 minutes.
Whether you want sprinkles, rasps or drops is up to you. Also tastes great warm with a glass of milk.
