  1. Step 1: Preheat oven to 350°F. Grease and flour a 9x5-inch loaf pan.
  2. Step 2: In a small bowl, combine 1 cup mashed ripe bananas with 1/4 cup spiced rum and set aside to soak for 10 minutes.
  3. Step 3: In a medium bowl, whisk together 1 3/4 cups all-purpose flour, 1 tsp baking soda, and 1/2 tsp salt.
  4. Step 4: In a large bowl, beat 1/2 cup softened unsalted butter and 3/4 cup granulated sugar with an electric mixer on medium speed until light and fluffy, about 3 minutes.
  5. Step 5: Add 2 large eggs one at a time, beating well after each addition, then mix in 1 tsp vanilla extract.

  7. Step 7: Pour the batter into the prepared loaf pan and bake for 60-70 minutes until a toothpick inserted in the center comes out clean and the edges are golden brown.
  8. Step 8: Cool the bread in the pan for 15 minutes before transferring to a wire rack to cool completely.
