Whip the cream with the sugar and vanilla essence to stif peaks.
Using a fork wish the mascarpone until smooth and fold the cream in.
Add the Dutch eggnog to taste. I think I used more then the required 1,5 dl as I thought the taste was not strong enough yet but it depends on personal preference...
Dip the amaretti cookies in the coffee and put them in the bottom of 8 small glasses. If the cookies are too big break them up as needed. Add one layer of the mascarpone mixture on top of the cookies and repeat this once.
End with a layer of mascarpone and put in the fridge for at least 4 hrs or preferably overnight.
Before serving grate some white chocolate over the top
