Clean well cooled boiled egg. We will only need the yolks. Protein can be filled with any filling and devour while you prepare the cookies.

Well. Back to the yolks. They should be thoroughly mashed to avoid lumps.

Sugar RUB with margarine (butter). /Margarine in advance, remove from refrigerator to cooking he was not "oak"./

Add to the mixture the flour and pre-grated egg yolks

Mix first with a spoon or fork (whatever you like)

Then the means at hand to put aside the ordinary people's way - a hand - kneaded dough

Light the oven. Let it warmed up. Unfortunately the temperature can not specify. My oven is not showing it : ( But this time roll the "sausages" with a length of 3-4cm and put on a pre-greased broiler. Even on the foil spread.

To bake 30-40 minutes. To be honest, my oven have dealt with this faster. When the cookie is baked, remove it from the oven and spread on a dish. Give a well to cool. Almost completely. In the meantime prepare the icing sugar and cocoa. Ideally you want a practical cold cookies first, dip in powdered sugar and then cocoa powder. To be honest, I tried to do so, but spit on all and mixed in one dish powder and cocoa and dipped the biscuits in the ready-made mix ;).

And the result here is a treat! I ate with great pleasure. God forbid to daydream while eating cookies... relatives will not remain ;). I was able to stop in time and brought friends to work to try. All were delighted! Enjoy your meal :)
