In a medium saucepan, heat the milk and heavy cream over medium heat until it almost reaches a simmer. Do not let it boil!
Meanwhile, in a separate bowl, whisk the egg yolks with the sugar until light and creamy.
Gradually, while whisking constantly, add a small amount of the warm milk mixture to the egg yolk mixture to temper the eggs and prevent them from curdling.
Pour the entire mixture back into the saucepan and cook over low heat, stirring constantly, until it thickens. It's ready when it coats the back of a wooden spoon.
Remove from heat, then stir in the vanilla extract and a pinch of salt. Let it cool completely.
Puree the bananas until smooth, then add them to the cooled ice cream base and mix well.
Pour the mixture into an ice cream maker and churn according to the manufacturer's instructions.
When the ice cream is almost completely churned, add the finely chopped dark chocolate and ground walnuts, distributing them evenly.
Transfer the finished ice cream to an airtight container and freeze for at least 3 hours to reach the desired consistency.
