Place chocolate into the Thermomix bowl. Melt 7 minutes/40/speed 1. Scrape bowl occasionally to ensure chocolate is beneath the blades.
Add condensed milk, EVOO and vanilla and blend 20 sec/speed 6. Scrape bowl and repeat. Set aside.
Without cleaning the bowl, place cream into bowl and whip 15-30 sec/Butterfly/speed 4 or until the cream is holding soft peaks.
Remove the Butterfly and place the milk mixture back into the bowl and blend 3 sec/speed 6.
Fold through with a spatula and pour into your Ice Cream Churner.
Alternatively, if you don't have a churner, pour mixture directly into an insulated container and freeze for at least 4 hours.
