How to make
Mash the biscuits. Melt the butter, add 1/2 tbsp coffee. Add the mixture to the biscuits and stir until homogeneous.
Put it in a form with a cake ring, press it toward the bottom and place it in the fridge. Pour 12 tbsp cold water over the gelatin and leave it to swell.
Dissolve it in a water bath and mix with the remaining coffee. Beat the mascarpone with the powdered sugar and yoghurt. Add the coffee with the gelatin and stir everything very carefully.
Pour this mixture over the biscuit layer and leave it in the fridge for 8 hours to harden completely. Before serving, grate the chocolate coarsely and sprinkle it over the cake.
