Heat the milk and stir in the mascarpone and vanilla extract until you won't see any lumps.
When the milk boils, turn off the heat and stir in the white chocolate.
Let the mixture stand for 5 minutes, then stir again.
Put the hot pan in a bowl of cold water so it cools quickly.
Put the ice cream base in the refrigerator and make sure that it cools down completely.
Whisk the cold mixture 2 minutes with the mixer and pour into a plastic container with lid and put in the freezer
Stir every 30 minutes with a fork, until the ice cream is hard.
NOTES
If you have an ice cream machine pour the cooled chocolate mixture in the ice cream machine and put it on for 30 minutes. Scoop the ice in a freezing box and put it in the freezer for another hour.
substitute full milk for skinny milk to get fewer calories.
Tasty: chop 50 grams extra white chocolate and mix that with the mascarpone mixture when it has cooled in the refrigerator ( and before the mixture is poured into the ice machine)
Serve with chopped walnuts and chocolate sauce. Or with caramel sauce and fresh fruit.
