Bananas Foster is a dessert made from bananas and vanilla ice cream, with the sauce made from butter, brown sugar, cinnamon, dark rum, and banana liqueur. The butter, sugar and bananas are cooked, and then the alcohol is added and ignited. The bananas and sauce are then served over the ice cream. The dish is sometimes performed.

The dish was created in 1951 by Paul Blangé at Brennan's Restaurant, The Commander's Palace in New Orleans, Louisiana. It was named for Richard Foster a friend of Owen Brennan's and New Orleans Crime Commission chairman.
