Place chocolate bars on slightly rolled out dough, exactly in the middle. Then trim the corners of the dough to form a cross with a chocolate center.
On the sides, make cuts in the form of strips about 2 cm wide. It is better to make them at an angle, from the chocolate to the edge of the dough. Sprinkle the chocolate with nuts.
Fold the top and bottom edges of the dough over the chocolate and nuts, and fold the side lines into a spikelet, folding one strip over the other so that the structure does not fall apart.
Beat the egg and brush the top of the roll with it. The dessert is almost ready. Place it in the oven preheated to 170 ℃ for 20-25 minutes until golden brown.
