This Tiramisu naked cake with mascarpone frosting is creamy, rich and has a bit of a kick! Well Tiramisu means 'pick me up' after all...
Make sure both the cheese and creme fraiche are cold when using. The creme fraiche needs to be thick in order for this frosting to not be too runny. You can replace with equal amouns of whipped double (heavy) cream if lactose is not a concern.
If the frosting becomes too runny you can rescue it by adding some gelatine. Sprinkle 1 tbsp powdered gelatine over 3 tbsp hot water and stir really well until dissolved. Allow it to cool. Mix in with the frosting and chill until it becomes firm enough to work with.
You can use Amaretto, Tia Maria or Kalhua instead of Marsala wine, although the taste will be different with each one (use your favourite).
