Melt the chocolate in a small pan over a bigger pot with boiling water.
Beat the mascarpone until fluffy.
Add the melted chocolate to the mascarpone and stir well.
Take 1 biscuit and cover with mascarpone-chocolate cream. Place another biscuit on top of it.
Repeat this step until you get 12 biscuit sandwiches.
Take 1 sandwich and soak for 1 second in the hot cocoa.
Cover one side with cream and set aside.
Soak another biscuit sandwich in cocoa and stick it to the previous one on the creamy side.
Place this "brick" on a plate.
Keep soaking biscuit sandwiches and adding them to the salami until there is no pair left.
Use the remaining cream to cover the salami using a spatula.
Place the roasted peanuts on half of a large piece of parchment paper.
Fold the other half and use a rolling pin to crush the peanuts.
Sprinkle the pieces over the salami.
Refrigerate for at least one hour before serving.
