Beat the Tiramisù dessert base in a mixer for approximately 3 minutes. Transfer to a piping bag.
Pipe three-quarters of the way into individual moulds and tap to remove any air bubbles.
Prepare the coffee syrup by combining the coffee, sugar, and water. Soak the ladyfinger biscuits in the syrup and place on top of the tiramisù. Freeze for at least 3 hours. Remove from the moulds and set aside in the fridge.
Prepare the mixture for the finishing touches: combine the Tiramisù dessert base, the liquid coffee, and the milk.
When time to serve, pour the liquid mixture in the center of the dessert.
The coffee may be replaced by chicory!
