There’s something absolutely magical about a Bacardi Rum Cake – it’s the kind of dessert that feels fancy enough for a dinner party but easy enough for a weeknight treat. This classic recipe has been a beloved staple in Caribbean and American kitchens for generations, and once you taste a slice of this moist, boozy masterpiece, you’ll understand why.
The beauty of this Bacardi Rum Cake lies in its simplicity and the way the dark rum infuses every crumb with rich, sophisticated flavor. Unlike some rum cakes that can be dry or overly dense, this version strikes the perfect balance between moisture and structure. The cake itself is tender and fluffy, while the rum glaze soaks in to create pockets of intense rum flavor throughout. Whether you’re celebrating a special occasion or simply craving something indulgent, this recipe delivers every single time.
What makes this Bacardi Rum Cake truly special is the combination of techniques that keep it incredibly moist. We’re using both rum in the batter and in the glaze, which means you get that delicious boozy flavor in every bite. The cake is also brushed with a rum syrup while it’s still warm from the oven, allowing the liquid to absorb deeply into the crumb structure. This is a trick that professional bakers use, and it makes all the difference in achieving that signature dense-yet-moist texture.
I love serving this cake with a simple dusting of powdered sugar or a dollop of whipped cream. Some people enjoy it with a cup of coffee in the afternoon, while others prefer it as a decadent dessert after dinner. The beauty of this recipe is its versatility – it’s sophisticated enough for entertaining but approachable enough for everyday enjoyment.

Ingredients
- 1 cup (2 sticks) unsalted butter, softened to room temperature
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup Bacardi Superior white rum, divided
- 1/3 cup dark rum (optional, for deeper flavor)
- 1 cup granulated sugar
- 4 large eggs, room temperature
- 1/2 cup sour cream, room temperature
- 1/4 cup fresh lemon juice
- 2 tablespoons lemon zest
- 1 teaspoon vanilla extract
- 1/2 cup chopped pecans or walnuts (optional)
- 1 cup granulated sugar (for the glaze)
- 1/2 cup Bacardi Superior white rum (for the glaze)
- 6 tablespoons unsalted butter (for the glaze)
- Powdered sugar for dusting (optional)
Instructions
- Preheat your oven to 325°F (160°C). Grease a 10-inch bundt pan generously with butter or non-stick cooking spray, making sure to coat every crevice. This is crucial for easy cake removal. Set aside.
- In a small bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set this dry mixture aside.
- In a separate small bowl, combine 1/2 cup Bacardi Superior white rum with the dark rum (if using) and set aside.
- Using an electric mixer on medium speed, cream together the softened butter and 1 cup granulated sugar until the mixture is light, fluffy, and pale in color, approximately 3-4 minutes. Stop occasionally to scrape down the sides of the bowl.
- Add the room temperature eggs to the butter mixture one at a time, beating well after each addition. This ensures proper emulsification and a tender crumb. If the mixture looks slightly curdled, don’t worry – it will come together.
- In a small bowl, whisk together the sour cream, fresh lemon juice, lemon zest, and vanilla extract.
- Add half of the dry flour mixture to the butter and egg mixture, beating on low speed until just combined. Be careful not to overmix, as this can lead to a tough cake.
- Pour half of the rum mixture into the batter and fold gently with a spatula until just combined.
- Add the remaining dry flour mixture and beat on low speed until just combined.
- Pour the remaining rum mixture into the batter and fold gently until the batter is just combined. Do not overmix.
- Gently fold in the sour cream mixture using a spatula until the batter is smooth and uniform.
- If using nuts, toss them lightly in a tablespoon of flour to prevent them from sinking, then fold them into the batter.
- Pour the batter into your prepared bundt pan, smoothing the top gently with a spatula.
- Bake in the preheated 325°F oven for 50-55 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs. The cake should be golden brown on top.
- While the cake is baking, prepare the glaze. In a saucepan, combine 1 cup granulated sugar, 1/2 cup Bacardi Superior white rum, and 6 tablespoons unsalted butter.
- Bring the glaze mixture to a gentle simmer over medium heat, stirring occasionally, and let it simmer for about 3-4 minutes. The mixture should thicken slightly. Do not boil vigorously.
- Remove the glaze from heat and let it cool for 2-3 minutes.
- When the cake comes out of the oven, let it cool in the pan for about 10 minutes.
- Using a skewer or toothpick, pierce the entire surface of the warm cake multiple times. This creates channels for the glaze to penetrate and keeps the cake incredibly moist.
- Slowly pour about half of the warm glaze over the warm cake, allowing it to soak into all the little holes you’ve created. Pour gradually so the glaze has time to absorb rather than running off the sides.
- Let the cake sit in the pan for another 10-15 minutes, then carefully invert it onto a serving plate.
- Pour the remaining warm glaze over the top and sides of the inverted cake, allowing it to drip down naturally.
- Let the cake cool completely to room temperature before serving. This allows the glaze to set and the flavors to fully develop.
- If desired, dust with powdered sugar just before serving. Store covered at room temperature for up to 3 days, or wrap and refrigerate for up to a week.
Pro Tips
Don’t Overmix: Once you add the dry ingredients, mix only until just combined. Overmixing develops gluten, which leads to a tough, dry cake. Fold gently when combining wet and dry ingredients.
The Glaze Is Essential: This isn’t just frosting – it’s what makes this rum cake so moist and flavorful. Pour it slowly while both cake and glaze are still warm so it can properly absorb. This step is what separates a good rum cake from an extraordinary one.
Rum Selection: Bacardi Superior white rum provides a clean, smooth flavor, but don’t hesitate to add the optional dark rum for deeper, more complex notes. The dark rum adds caramel and molasses undertones.
Bundt Pan Preparation: A properly greased bundt pan is crucial. Use butter rather than non-stick spray for best results, as it helps the cake release cleanly. Pay special attention to the center tube and ridges.
Skewer Piercing: This technique, called “poking,” allows the warm glaze to penetrate the cake thoroughly. Make numerous holes throughout the cake, going about halfway to two-thirds of the way through.
Storage Tips: This cake actually improves after a day or two as the flavors meld and the moisture distributes evenly. Store it covered at room temperature for up to 3 days, or wrap it well and refrigerate for up to a week.
Scaling the Recipe: This recipe can be halved and baked in a smaller loaf or round pan, reducing the baking time to 35-40 minutes. Check for doneness with a toothpick.
Alcohol Content: If you prefer to reduce the alcohol content, you can use less rum in the batter and glaze. The cake will still be delicious, though slightly less boozy.
Serving Suggestions: This cake pairs beautifully with coffee, tea, or even a glass of rum. It’s also delicious with a dollop of whipped cream or vanilla ice cream for serving as a dessert.
