Totally worth the beaucoup bucks and frozen noses!
Then we got back home and were on a mission to recreate it here in our own kitchen. Here's our version. Keep in mind that the better chocolate you use the more heavenly it will be!
The ingredients:

(ignore the Ferrero Rochers in there--they didn't work)
6 half-ounce pieces of a variety of your favorite chocolates
2 tsp. store bought hot chocolate mix
1-1/2 Tbs. sugar
1-1/2 cups milk
3 cups ice
Whipped cream
Chocolate shavings

Chop the chocolate into small pieces and place it in the top of a double boiler (we made one with metal bowl that fit over a sauce pan) over simmering water, stirring occasionally until melted.

Add the cocoa and sugar, stirring constantly until thoroughly blended. Remove from heat and slowly add 1/2 cup of the milk and stir until smooth.

Cool to room temperature.
In a blender place the remaining cup of milk, the room temperature chocolate mixture, and the ice.

Blend on high speed until smooth and the consistency of a frozen daiquiri.

Pour into a giant goblet (we don't own any giant goblets) and top with whipped cream and chocolate shavings. Don't drink the whole thing yourself! Makes 4 normal sized servings or two Serendipity sized ones.
Enjoy!
