Why This Recipe Works

Bananas Foster is a delicious and impressive dessert that involves flambéing bananas in rum and serving them over ice cream. For a more party-friendly dessert, we fill layers of yellow cake with bananas cooked in a rum-laced caramel. The fluffy frosting gets a generous dose of rum as well, and the cake is topped with banana slices and more of the caramel sauce, enriched with butter for extra decadence.
