With a stand up mixer or hand held mixer, beat together the heavy whipping cream and vanilla extract until the cream is whipped and can form soft peaks.

Place the bananas in a blender or food processor and blend them until pureed and smooth.

In a separate bowl, stir together the sweetened condensed and the pureed bananas.

Then gently fold in the whipped cream into the sweetened condensed milk mixture.  Then gently fold in the walnuts and chocolate chunks.

Spread the mixture into a loaf pan and freeze for at least 4 hours until firm.

Serve and enjoy!  The ice cream will keep covered in the freezer for up to 1 month.
