Knead a shortcrust pastry from flour, butter, egg, coffee and sugar and chill for 1 hour.
In the meantime, chop the couverture. Bring the cream to the boil and remove from the stove. Add the couverture and stir until smooth. Let cool down.
Cut round biscuits out of the dough and bake at 175 ° C for about 10-12 minutes.
After cooling, spread the spreadable couverture cream, except for 4 tablespoons, on half of the biscuits and top with the remaining biscuits. Put the rest of the cream in the middle of the biscuits and cover with mocha beans. Dust with cocoa.
