How to make
Beat the mascarpone cream, sugar and vanilla with a mixer. Melt the chocolate in a water bath.
In a blender, crumble the cocoa biscuits into crumbs. In a cake form, begin to lay out a row of plain biscuits, dipping each one briefly in milk, put 1/3 of the cream with mascarpone on top, then on top of the cream put the crumbs of the cocoa biscuits and pour on 3 spoons of melted chocolate.
Make the second row in the same way. On the third - put the mascarpone cream and cocoa biscuits but before pouring on the liquid chocolate, sprinkle with sliced almonds for a decorative look.
