Blend the biscuits in a food processor to a fine powder. Add sugar, coconut and melted butter. Mix and add milk. Put the whole mass into the blender again and mix until you get a uniform mass.
Take out the mass and shape it into a form of salami. Wrap in food foil and put in the fridge for half an hour.
Melt the chocolate in a water bath, add butter and oil and combine together.
Take out "the salami", cover it with the prepared chocolate and let it harden. Cut into slices and serve. Enjoy!
