Place the mass in a silicone mold for sticks and  put it in the freezer for 1 hour.

Meanwhile, prepare the icing by  melting all the chocolate in a bain-marie.

Then mix it  with vegetable oil. 

Chop or grind the unsalted peanuts again and  mix them with the chocolate. 

When the mass hardens, we place the bars on the rack and  cover them with the prepared chocolate coating. 

Let it  harden in the refrigerator  and we can serve.
