Make first the layer of black chocolate, then milk chocolate, and finally white chocolate. The steps are the following for each layer:
(Start with black chocolate)
1 - Soak the 4 gelatin sheets in cold water.
2 - Whipe the 200 ml of cream. Reserve a large bowl.
3 - In a saucepan, heat the 250 ml of milk with 2 tablespoons of sugar, add the well drained gelatin and chocolate chunks. Allow to warm 10 minutes.
4 - Mix the cream with a stick, but with encircling movements, not beating, pour on top of the cookies and carry the refrigerator for at least 2 to 3 hours, until solid.

(After 2 hours you can start to cook the white chocolate layer. When it is finished wait for another 2 hours and cook the white layer)

Tips_ Make lines with a fork before adding the second and third layer to make them join together.
