Baba Au Rhum is a traditional French dessert that consists of a small yeast cake soaked in a rum syrup. The cake is typically light and airy, made with ingredients like flour, eggs, sugar, and butter. It is often served with whipped cream or pastry cream, enhancing its rich flavor. Originating from Eastern Europe, the dessert was popularized in France in the 19th century. The name "baba" is derived from the Polish word "baba," meaning "grandmother." The addition of rum gives the cake its distinctive taste, making it a favorite in many patisseries and restaurants.
