For the caramel Nana Ice Cream, first prepare the caramel sauce. To do this, lightly caramelize the sugar, add the butter and foam it, then pour in the whipped cream. Reduce a little and then let it cool down a bit.
Finely mix the bananas with 2 tablespoons of caramel sauce. If necessary, add milk for a creamier consistency.
Coarsely chop the caramel candies. Sprinkle caramel Nana Ice Cream with caramel pieces and chopped nuts.
Peel the bananas for the Caramel Nana Ice Cream the day before, roughly slice and freeze.
