Slice the bananas in three slices lengthwise, then cut in halves.
Melt the butter in a skillet or frying pan, add brown sugar (you
may also add 1/2 teaspoon cinnamon if desired) and cook over low heat, stirring into a thick paste. Add vanilla and banana liqueur and stir well. Cook about 3 minutes. Add banana slices and cook over medium heat, basting well with the sugar and butter mixture. Cook about five minutes. (Mixture will bubble while cooking.)

Heat the rum in a metal cup, ignite, and pour over bananas. (Run
will have faint blue flame in cup and will flame up when poured
over the bananas.) Stir well to blend, then serve mixture with
pieces of bananas over vanilla ice cream.

Note: Be careful while handling the flaming rum.
