  5. Put dark chocolate in one part, white in the other and mix well until chocolate is melted. Cover with nylon foil and cool nicely. 
  6. After they cool down nicely, whisk 125 g of butter or margarine on the side and put half of the butter in the white filling, whisk well, and put the other half of the butter in the dark filling and whisk it nicely as well.
Arranging the cake
Take one strip of the sponge cake, coat it with 1/3 of white filling, then apply from the brown filling. The same is repeated with the other 2 crusts and the whole cake is coated with the brown filling. If desired, coat the whole cake with whipped cream.
