Melt 2/3 of the chocolate au bain marie. 
Once melted add the remaining chocolate and stir until it's all melted. 

Make with a spatula long broad stripes on a baking sheet (as long as the mold you will put the ice in).
Let it harden in the freezer for a couple of minutes.

Beat the condensed milk with the cream in the KitchenAid for approx. 10 minutes on high speed. 

Put plastic foil in a long cake mold. Then start layering, starting with a layer of cream, then a stripe of chocolate and so on and finish with a layer of cream.

Put in the freezer for minimum 4 hours or make it a day in advance.

When serving, finish with some melted chocolate on top and cacao. 

I am so happy I've made this classic Viennetta for the very first time! Since forever I can remember this has been a tradition in our family. From eating it at my grand-parents place, to my parents place to me making it myself now. How proud my grand-mother would have been. 

This one's for her! 

Buon Appetito & Merry Christmas!
