What cocktail is made from cognac, crème de cacao, and cream?

A Brandy Alexander is a brandy-based dessert cocktail consisting of cognac, crème de cacao, and cream, that became popular during the early 20th century. It is a variation of an earlier, gin-based cocktail called simply an Alexander. The cocktail known as Alexander today may contain gin or brandy. Ice cream can be added for a "frozen Brandy Alexander".

There are many rumours about its origins. Some sources say it was created at the time of the London wedding of Princess Mary and Viscount Lascelles in 1922. Drama critic and Algonquin Round Table member Alexander Woollcott said it was named after him. Other sources say it was named after the Russian tsar Alexander II.

The drink was possibly named after Troy Alexander, a bartender at Rector's, a New York City restaurant, who created the drink in order to serve a white drink at a dinner celebrating Phoebe Snow, a character in a popular advertising campaign in the early 20th century.
