Thin out the Nutella a little, either by placing in a bowl over a pot of boiling water or microwave.
In a large bowl whip the cream until stiff peaks appear.
Add a little whipped cream to the sweetened condensed milk mixture to make it easier to combine, then fold it into the remaining whipped cream.
Fold in chocolate chips, then pour into a loaf pan approximately 8 inches (20x10 cm). Pour the thinned out cooled Nutella on top and with the tip of a knife mix it into cream mixture. Cover with plastic wrap and freeze for 8-10 hours until firm or even over night. Enjoy!
Notes
How to store Homemade Ice Cream
Homemade ice cream / gelato should be kept in the freezer, in an airtight container. Apparently glass or stainless steel are the best containers to use. It will keep for up to 2 weeks in the freezer.
