This moist and flavorful Rum Banana Bread is a tropical twist on the classic comfort bake. Ripe bananas, warm spices, and a touch of rum come together to create a perfectly tender loaf topped with a rich rum glaze.

Ingredients
For the Banana Bread
- 3 large overripe bananas, mashed (about 1¼ cups)
- ½ cup packed brown sugar
- ½ cup unsalted butter, plus 1 tablespoon for greasing the pan
- 3 tablespoons dark or spiced rum (such as Captain Morgan)
- 2 large eggs, room temperature
- ¼ cup vegetable oil
- ¼ cup sour cream, room temperature
- ¼ cup buttermilk, room temperature
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour, spooned and leveled
- ⅔ cup granulated sugar
- 1 teaspoon baking soda
- 1 teaspoon ground nutmeg
- ½ teaspoon salt
- ¼ teaspoon ground cinnamon
- ¼ teaspoon ground cardamom
For the Glaze
- 1–2 cups powdered sugar
- 1–2 tablespoons rum
- 2 tablespoons unsalted butter, melted
Instructions
- Preheat the oven
Preheat your oven to 350°F (175°C) and adjust the rack to the lower-middle position. - Prepare the loaf pan
Grease an 8.5 x 4.5-inch light-colored loaf pan with softened butter, making sure to cover the bottom, sides, and corners. Dust lightly with flour, then tap out any excess. - Cook the banana mixture
In a medium skillet, combine the mashed bananas, brown sugar, butter, and rum.
Cook over medium heat until the butter melts and the mixture begins to simmer.
Reduce heat to low and simmer for 3–5 minutes, whisking occasionally.
Remove from heat and allow to cool for about 10 minutes. - Mix the wet ingredients
In a large mixing bowl, whisk together the eggs, oil, sour cream, buttermilk, and vanilla extract.
Stir in the cooled banana mixture until fully combined. - Combine the dry ingredients
In a separate bowl, whisk together the flour, granulated sugar, baking soda, salt, nutmeg, cinnamon, and cardamom. - Combine wet and dry ingredients
Add the dry ingredients to the wet mixture and gently fold until just combined.
Do not overmix — this keeps the bread soft and fluffy. - Bake
Pour the batter into the prepared loaf pan and bake for 60–65 minutes, or until a toothpick inserted in the center comes out clean. - Cool
Allow the banana bread to cool completely in the pan before removing. - Prepare the glaze
In a small bowl, whisk together powdered sugar, melted butter, and rum.
Adjust the consistency — use more powdered sugar for a thicker frosting or more rum for a thinner glaze. - Glaze and serve
Once the bread is completely cooled, drizzle or spread the glaze on top. Slice and enjoy!

FAQs
Can I make this bread ahead of time?
Yes! It tastes even better the next day. Store it covered at room temperature for up to 3 days or refrigerate for up to a week.
Can I freeze it?
Absolutely. Wrap the cooled loaf (without glaze) tightly in plastic wrap and freeze for up to 3 months. Thaw overnight before glazing.

Dark or spiced rum adds the richest flavor, but light rum works for a milder taste.
