From this set of products I got 33 cookies. :) So, in flour, add cold butter, cut into cubes, and well grind everything together with your hands into crumbs.

Add the powdered sugar and baking powder, mix.

Eggs lightly whisk until smooth. 4 tbsp set aside in a separate bowl - it will be used to cover the surface of the cookies.

The rest of the eggs add to flour mixture and knead homogeneous dough. Wrap it in cling film and refrigerate for 15 minutes.

Chocolate melt in a water bath, add milk, quickly stir and let the mixture cool slightly at room temperature.

Next, I did the next best thing. Took half of the dough from the fridge, roll it into the reservoir of 3 mm, is cut 10 circles with a diameter of 6 cm and 10 clubs - 7 see Remnants of this formation is mixed with a part of holodilnike. On smaller circle put 0.5 tsp. of chocolate.

Delicately cover it a large circle, zasiyaet edge, trying not to let the filling leak out (it's not hard). Then, for beauty, I trim the edge of the mould 7 cm make 10 cookies. Then repeat the procedure with half of the dough from the refrigerator and until the dough will not end. Why not roll out all the dough at once? Cold easier to work with. I baked in two approaches in 180 gr. 12-15 minutes, pre-covered biscuits with egg mixture.
