This hot chocolate lives up to its name. It is deeply rich and chocolatey without being cloyingly sweet. And it is so thick and creamy, you’ll be tempted to eat it with a spoon.

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.

This drink is so rich, it should be served in espresso cups. If you like, top it with a dollop of whipped cream.

And whatever you do, make sure there are leftovers. Cover and refrigerate them overnight. By morning they will have been transformed into chocolate mousse.
