Rum Banana Bread

My Rum Banana Bread is moist, easy to make and full of banana flavor! The addition of rum brings a rich, complex, and slightly boozy flavor to the banana bread without it really tasting like alcohol at all. The rums role is to help add moisture, make it tender and all in all, it's a fun twist on the homemade classic banana bread loaf!

Ingredients

  • 3 large over ripe bananas, mashed (~1 1/4 cups)
  • 1/2 cup brown sugar, packed
  • 1/2 cup unsalted butter (plus 1 Tbsp. for greasing the loaf pan)
  • 3 Tbsp. Dark Rum or Spiced Rum I use Captain Morgan
  • 2 large eggs, room temperature
  • 1/4 cup vegetable oil
  • 1/4 cup sour cream, room temperature
  • 1/4 cup buttermilk, room temperature
  • 1 tsp. vanilla extract
  • 2 cups flour, spooned and leveled
  • 2/3 cup granulated sugar
  • 1 tsp. baking soda
  • 1 tsp. ground nutmeg
  • 1/2 tsp. salt
  • 1/4 tsp. cinnamon
  • 1/4 tsp. cardamom
For the glaze:
  • 1-2 cups powdered sugar
  • 1-2 Tbsp. rum
  • 2 Tbsp. unsalted butter, melted

Instructions

    Cup of Yum
  1. Preheat oven to 350°F. Be sure to adjust the oven rack to the lower-middle position.
  2. Grease the pan: Grease a 8.5 x 4.5 inch light colored loaf pan with softened butter. Evenly spread a thin layer of butter over the interior surface of the loaf pan. Be sure to cover the bottom and sides, including the corners. Add a tablespoon or two of all-purpose flour to the pan. Tilt and rotate the pan, tapping it gently, to distribute the flour evenly across the greased surface. The flour will stick to the butter, creating a light, floury coating. Hold the greased and floured pan upside down over the sink or a trash can to allow any excess flour to fall out. Gently tap the pan to help remove loose flour.
  3. In a medium skillet add the mashed bananas, butter, brown sugar, and rum. Cook and whisk banana mixture over medium heat until butter melts and mixture begins to simmer. Turn the heat down to low and let simmer for ~3-5 minutes, whisking occasionally.
  4. Remove from heat and let slightly cool for about 10 minutes. It does not have to cool all the way, but just so it is not super hot. (If you are folding in chocolate chips into the batter you will want it to cool completely).
  5. In a large bowl, combine the eggs, oil, sour cream, buttermilk, and vanilla extract.
  6. Add the cooled banana mixture to this and whisk together.
  7. In a separate mixing bowl, combine the flour, sugar, baking soda, salt, nutmeg, cinnamon, and cardamom.
  8. Add the dry ingredients to the wet ingredients and gently fold until combined. Do not over mix the batter.
  9. Pour this mixture into the prepared pan.
  10. Bake for ~60-65 minutes, or until a toothpick comes out clean.
  11. While the bread cools, you can prepare the frosting. Whisk powdered sugar, rum and butter together. Add more or less powdered sugar and rum until you get the desired frosting consistency; either drippy for a glaze or more thick like a frosting in the photos. 
  12. Make sure your bread is 100% cooled down before you drizzle the frosting over the bread. Enjoy!

Notes

  • Jan 2024 update: this recipe has been modified from the original recipe. My original recipe had 1 1/2 cups sugar, 5 Tbsp. butter, no sour cream, and I baked it at 325°F for 70 minutes. After making multiple times, the loaf was collapsing in the middle so with my new and perfected recipe, you get a beautiful loaf that rises in the middle, is ultra moist and tender and full of banana flavor!
  • Storage: bread keeps for 2-3 days at room temperature. I love this bread best on days 2 and 3 actually! Warmed in the microwave and then with a little butter on top. So good! This loaf can also keep in the fridge for 1 week or up to 2-3 months in the freezer, just be sure to tightly wrap it.
