Ingredients of Banana Rum Cake
When it comes to baking, having the right ingredients is half the battle. For this delightful Banana Rum Cake, you’re going to need a mix of classic baking staples and a touch of tropical flair. The beauty of this recipe lies not just in the flavors but also in the simplicity.
Grab your apron, and let’s gather what you need to create this scrumptious cake that’ll have everyone asking for seconds.
Here’s what you’ll need:
- 1 (18 1/4 ounce) package yellow cake mix
- 1/4 teaspoon baking soda
- 2/3 cup dark rum
- 2/3 cup water
- 2 eggs
- 1 cup mashed banana (the riper, the better)
- 1/3 cup chopped pecans
- 1/3 cup butter, softened
- 3 cups confectioners’ sugar
- 2 teaspoons vanilla extract
- 2 tablespoons dark rum (for the frosting)
Now, before you dart off to the store, let’s chat a bit about these ingredients. The yellow cake mix is your base, giving that soft and fluffy texture that pairs beautifully with the dense, moist banana.
And trust me, you want those bananas to be ripe—like, on-the-verge-of-browning ripe. They add natural sweetness and moisture, making your cake absolutely irresistible.
As for the dark rum, it’s not just for flavor; it brings a warmth that just screams comfort food.
Oh, and don’t skimp on the frosting; it’s the cherry on top—or should I say, the rum on top? It adds that extra layer of decadence that really makes this cake shine.
How to Make Banana Rum Cake

Alright, let’s roll up those sleeves and plunge into making this delicious Banana Rum Cake. First things first, preheat your oven to 350 degrees F (175 degrees C). Trust me, you want that oven nice and toasty by the time your batter is ready.
While that warms up, grab those two 9-inch cake pans and grease them up with some butter or cooking spray, then sprinkle a little flour in there. It’s like giving your cake a cozy little bed to bake on.
Now, in a large mixing bowl, combine that 18 1/4-ounce package of yellow cake mix with 1/4 teaspoon of baking soda. This combo is the foundation of your cake, and believe me, it’s going to be fluffy and delightful.
Next, pour in 2/3 cup of dark rum and 2/3 cup of water—yes, that rum is going to lend such a warm, comforting flavor. Crack in 2 eggs and add in 1 cup of mashed banana. The riper the banana, the better, folks. If your banana looks like it could star in a horror movie, you’re on the right track.
Finally, toss in 1/3 cup of chopped pecans for that lovely crunch. Mix it all together until it’s well combined—beat it on medium speed for about 2 to 4 minutes. If it looks like a magical banana mix, you’ve done it right.
Once your batter is ready, it’s time to divide it evenly between those prepared pans. Slide them into the oven and let them bake for about 25 to 30 minutes. You’ll know they’re done when a toothpick poked into the center comes out clean, which is always a satisfying moment.
While your cakes cool completely (and I mean completely, because no one likes a melted frosting situation), let’s whip up that dreamy frosting. In a bowl, blend together 1/3 cup of softened butter and 3 cups of confectioners’ sugar until it’s smooth and creamy.
Stir in 2 teaspoons of vanilla extract and 2 tablespoons of dark rum. It’s basically like a party in a bowl. Once your cakes are cool, layer them up with that luscious frosting in between and around the sides.
And there you have it, a beautiful Banana Rum Cake that’s bound to impress. Just don’t forget to save a slice for yourself—you deserve it.
Banana Rum Cake Substitutions & Variations
While I love the classic Banana Rum Cake, there are plenty of tasty substitutions and variations you can try to make it your own.
For a gluten-free option, swap the yellow cake mix for a gluten-free blend. You can also use overripe bananas for added sweetness or experiment with different nuts like walnuts or macadamia nuts.
Want it richer? Try adding a layer of cream cheese frosting or even chocolate chips. If you’re looking for a tropical twist, incorporate pineapple or coconut.
Each variation brings a new flavor profile, making this cake endlessly customizable!
Additional Tips & Notes
Exploring substitutions and variations can elevate your Banana Rum Cake experience, but there are also a few tips to guarantee your cake turns out perfectly every time.
First, be sure to use overripe bananas; they’re sweeter and more flavorful. I recommend sifting the cake mix to prevent lumps.
When mixing, don’t overbeat the batter; a few lumps are okay. If you want extra moisture, consider adding a splash of buttermilk.
Finally, let the cake cool completely before frosting for the best texture. Your friends and family won’t believe how delicious your cake is, and you’ll be proud of your baking skills!
