For the light-dark little stars, knead and divide a nice shortcrust pastry from flour, margarine, sugar and yolks. Knead one half of the dough with the cocoa.
Cut out stars from the light dough and cut out stars with a hole in the middle from the dark dough. Bake the stars at 180 degrees for about 7 minutes.
When they have cooled down, glue them together with red jam mixed smooth with rum to make light-dark stars.
