Mix milk and cream powder in the high mixing bowl with the whisks of the hand mixer only at the lowest setting. Then whisk at highest setting for 3 minutes until creamy. Stir in 3 tablespoons of liqueur
Whip the cream until stiff and allow the vanilla sugar to trickle in. Add about 3/4 to the Baileys cream. Pour everything into four dessert glasses
Sprinkle half of each sponge finger with the remaining liqueur. Put 3 sponge fingers vertically into the Baileys cream. Chill for about 30 minutes
Spread the rest of the cream on the Baileys cream. Possibly decorate with candied nuts and mint
The Baileys cream is also a great dessert for the party. To make it, sprinkle the biscuits with liqueur in a large flat dish, cover with cream and whipped cream. This way it is even faster and takes less space in the fridge and on the buffet
