Mix the coffee beans with milk in a large bowl, cover and leave to cool overnight. The next day, pour 400 ml coffee-milk through a sieve into a pot, add 100 g cream and bring to the boil. Remove the pot from the heat, add the pudding powder with a whisk, stirring continuously, and continue stirring for about 1 minute. Let the pudding stand for about 3 minutes, stir vigorously again and fill into 4 cups or bowls. Let it cool down.
Biscuits crumble. Chop chocolate. Whip 100 g cream until creamy, spread as blobs on the pudding, sprinkle with cookie crumbs and chocolate.
