Mix 4 tablespoons of milk, pudding powder and sugar. Bring the rest of the milk to the boil, set aside. Add the pudding powder. Bring to the boil while stirring. Take a brown cake aside.
Break the rest of the cake several times and stir into the pudding. Pour into cold rinsed moulds (approx. 200 ml content). Chill for about 4 hours and turn out onto dessert plates. Whip cream and vanilla sugar until stiff.
Pour into a piping bag with a small star-shaped spout. Decorate the dessert with cream all around. Serve decorated with halved almonds, remaining finely crumbled cake and lemon balm.
