The drink owes its lush body in part to a banana that is pureed into the milk and cream. If the combination of chocolate and banana doesn't work for you, just leave it out and add another 1/4 cup of heavy cream.
1 cup milk
1/2 cup heavy cream
1 soft banana
3 ounces semisweet chocolate, finely chopped
3 ounces bittersweet chocolate, finely chopped
1/2 cup marshmallow spread
In a blender, combine the milk, cream, banana, cinnamon and salt. Puree until very smooth and thick. Pour the milk mixture into a small saucepan and set over medium heat.
Warm the mixture, whisking constantly, until it just barely comes to a simmer. Add both chocolates and the marshmallow spread. Whisk until completely melted and smooth.
Ladle the hot chocolate into espresso cups. If desired, top with a dollop of whipped cream.
