Follow these simple steps to create your own Bananas Foster:

1. Melt the Butter: In a large skillet over medium heat, melt the unsalted butter.
2. Add Brown Sugar: Once the butter has melted, stir in the brown sugar until well combined.
3. Cook the Sauce: Continue to cook the mixture, stirring occasionally, until the sugar dissolves and the mixture begins to bubble.
4. Add Bananas: Gently place the sliced bananas in the skillet, ensuring they are coated with the sauce. Cook for 2-3 minutes until the bananas are heated through.
5. Stir in Vanilla and Cinnamon: Add the vanilla extract and ground cinnamon, stirring to combine.
6. Flambé the Dish: Carefully add the dark rum to the skillet and ignite the sauce using a long lighter or match. Allow the flames to burn for 1-2 minutes until they extinguish naturally.
7. Finish with Nuts: Add chopped walnuts or pecans to the mixture, if desired, and gently stir.
8. Serve Immediately: Spoon the warm banana mixture over scoops of vanilla ice cream, allowing the sauce to melt over the top.
