Instructions

  1. Step 1: Melt 4 tbsp unsalted butter in a large skillet over medium heat for 1 minute until foaming but not browned.
  2. Step 2: Add 1/2 cup brown sugar and stir continuously for 3 minutes until the sugar dissolves completely and the mixture bubbles gently.
  3. Step 3: Carefully add 1/4 cup dark rum to the skillet and simmer for 2 minutes to reduce slightly and intensify the flavor.
  4. Step 4: Stir in 2 sliced ripe bananas, 1/2 tsp ground cinnamon, and 1 tsp vanilla extract. Cook for an additional 3 minutes, stirring frequently, until the bananas soften and the sauce thickens to a luscious consistency.
  5. Step 5: Remove from heat and serve warm drizzled over vanilla ice cream, pancakes, or French toast for a rich, rum-kissed dessert treat.
