Desserts
This Bacardi rum bundt cake delivers the perfect balance of boozy richness and tender moisture—every slice packed with deep caramel notes from the rum and a subtle citrus brightness that makes it irresistible. 💛 The secret lies in soaking the cake layers with extra rum syrup while baking, ensuring each bite stays perfectly damp without being soggy. I developed this recipe after years of baking bundt cakes, and this version consistently earns rave reviews for its texture and flavor complexity.
The cake's signature moistness comes from a combination of buttermilk, brown sugar, and the rum itself, which infuses the batter with warmth while keeping it tender. Unlike many rum cakes that can taste overly sweet or alcohol-heavy, this recipe achieves harmony through precise measurements and a citrus-kissed frosting that complements rather than competes with the rum's depth. The bundt pan creates those iconic ridges, adding visual appeal while ensuring even baking.
By the time you pull this cake from the oven, you'll have a golden-brown masterpiece with a fragrant aroma that fills your kitchen. The rum's caramelized sweetness shines through in every moist, tender bite, while the citrus frosting adds a refreshing contrast that balances the richness. This isn't just dessert—it's an experience that transforms any gathering into something special.
Perfect for celebrating birthdays, holidays, or simply treating yourself to something extraordinary. Pair it with a cup of strong coffee to enhance the rum's flavors or serve it with a side of fresh berries for a pop of color. The frosting's citrus notes cut through the cake's richness, making each bite feel like a luxurious indulgence. Let's get baking!
Ingredients for bacardi rum bundt cake
The secret to this boozy bundt masterpiece lies in these carefully balanced ingredients—rum-infused moisture meets citrus-kissed frosting perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Bacardi Superior Rum 🍹 | 1 cup | White rum, aged 3+ years |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, European preferred |
| Granulated Sugar 🍚 | 2 cups | White, fine granulation |
| Light Brown Sugar 🍚 | 1 cup | Packed, moist variety |
| All-Purpose Flour 🌾 | 3 cups | Sifted, plus extra for pan |
| Buttermilk 🥛 | 1 cup | Fresh, not powdered |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Baking Powder 🍃 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher |
| Vanilla Extract 🌸 | 2 tsp | Pure Madagascar preferred |
| Lemon Zest 🍋 | 1 tbsp | Fresh, organic preferred |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Powdered Sugar 🍚 | 4 cups | Sifted for frosting |
| Heavy Whipping Cream 🥛 | 1 ½ cups | Cold, full-fat |
| Lemon Extract 🍋 | ½ tsp | Pure, not imitation |
The rum is non-negotiable here—Bacardi Superior delivers the perfect balance of caramel depth without overpowering. Trader Joe's and Total Wine carry it at great prices, but any 3+ year aged white rum works. For the butter, European-style (like Plugrá) has higher fat content, which keeps the cake ultra-moist. The brown sugar should be packed—Domino brand works perfectly. If you're worried about alcohol content, reduce the rum to ¾ cup and add ¼ cup extra milk to maintain moisture.
No buttermilk? Mix 1 tbsp vinegar or lemon juice with 1 cup milk and let sit 5 minutes. Almond milk works too, but the cake will be slightly less tender. For the zest, organic lemons have more vibrant flavor—Whole Foods or local markets are best. The frosting's secret is cold cream—whip it in a chilled bowl for maximum volume. If you can't find lemon extract, double the zest and add 1 tsp more lemon juice. The vanilla extract should be pure—Madagascar bourbon or Tewksbury brands elevate the flavor.
Store the cake in an airtight container at room temperature for up to 4 days, or refrigerate for 1 week if you want to extend freshness. The frosting stays stable for 3 days at room temp—just re-whip before serving. For make-ahead prep, bake the cake 1 day ahead and frost just before serving. The flavors deepen overnight, making it even more irresistible. Freeze the unfrosted cake for 3 months if you're planning ahead—thaw at room temp before frosting.

Step-by-step instructions for Bacardi rum bundt cake
Here's how to craft a decadently moist rum cake with zesty frosting that's perfect for celebrations.
👨🍳 Step 1: Mix Wet Ingredients for Maximum Moisture
In a large mixing bowl, combine the 1 cup Bacardi Superior Rum with the 1.5 cups Unsalted Butter at room temperature. Whisk until the butter is completely melted and fully incorporated—this creates the cake's signature moist texture. In a separate bowl, whisk together the 2 cups Granulated Sugar, 1 cup Light Brown Sugar, 1 cup Buttermilk, 4 whole Large Eggs, 2 tsp Vanilla Extract, 1 tbsp Lemon Zest, and 2 tbsp Lemon Juice.
Here's the thing—adding the rum to the butter first helps distribute it evenly throughout the batter, preventing any alcohol pockets. The lemon zest and juice brighten the rum's richness, creating that perfect citrus-kissed balance. Let this wet mixture sit for 5 minutes while you prepare the dry ingredients—this resting period ensures everything comes together seamlessly.
👨🍳 Step 2: Combine Dry Ingredients and Create the Batter
In a medium bowl, sift together the 3 cups All-Purpose Flour, 2 tsp Baking Powder, and 0.5 tsp Salt. The sifting prevents lumps and ensures even distribution of leavening. Gradually pour the dry ingredients into the wet mixture while mixing on low speed with an electric mixer. Scrape down the sides of the bowl as needed to ensure all flour is incorporated.
Once fully combined, add the 0.5 tsp Lemon Extract and mix on low speed for another 30 seconds until just combined. This is crucial—the lemon extract adds depth without overpowering the rum. The batter should be smooth and slightly thick, like heavy pudding. If it looks too thick, add 1-2 tablespoons of additional buttermilk to reach the perfect consistency.
🔥 Step 3: Bake the Bundt Cake to Golden Perfection
Preheat your oven to 350°F and generously grease a 10-12 cup Bundt pan with butter, then dust with flour, tapping out any excess. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 50-60 minutes until a toothpick inserted in the center comes out clean and the cake springs back when gently pressed.
I know it's tempting to open the oven early, but resist! The cake needs that full baking time to develop its structure. If the top browns too quickly, tent the cake with foil after 30 minutes. The rum-infused cake will have a beautiful golden hue and that irresistible aroma that fills your kitchen. Let it cool in the pan for 15 minutes before inverting onto a wire rack to cool completely.
🥘 Step 4: Whip the Citrus-Kissed Frosting
In a large bowl, combine the 4 cups Powdered Sugar with the 1.5 cups Heavy Whipping Cream (cold) and the 0.5 tsp Lemon Extract. Using a stand mixer fitted with the whisk attachment, beat on high speed for 3-4 minutes until stiff peaks form. The frosting should be light, fluffy, and hold its shape when the whisk is lifted.
Here's a pro tip: Chill the mixing bowl and whisk beforehand—this helps the cream whip up faster and more stable. The lemon extract in the frosting complements the cake's rum flavor beautifully, creating that signature citrus-kissed balance. Spread the frosting over the completely cooled cake, then decorate with additional lemon zest or a dusting of powdered sugar for that elegant touch.
Pro Tips For Making Bacardi Rum Bundt Cake
- Warm the Rum First: Pour the Bacardi Superior Rum into a small saucepan and heat it gently for 30 seconds—just until it’s barely steaming. This wakes up the flavors and cuts through the richness of the butter and sugars, so the cake doesn’t taste like booze drowned in sweetness. (Yes, even if you’re impatient like me.)
- Cream Butter and Sugars Slowly: Beat the unsalted butter and sugars together on medium speed for at least 3 minutes before adding the rum. The butter needs time to lighten and emulsify with the sugars, or you’ll end up with a dense, greasy cake. I learned this the hard way—my first attempt was a brick.
- Don’t Overmix the Batter: Once you fold in the flour, stop mixing as soon as it’s just combined. Overworking the batter develops gluten, which makes the cake tough instead of tender. Use a spatula to gently fold—think "marble swirls," not "wallpaper paste."
- Test for Doneness with a Toothpick: The cake’s done when a toothpick comes out with a few moist crumbs, not wet batter. If you pull it out clean, it’s overbaked and dry. Cover it with foil 10 minutes before the suggested time if your oven runs hot—this keeps the top from drying out while the center finishes.
Flavor customization for these flavors
Spice Level Control
Adjust the rum's intensity by adding a pinch of cinnamon or nutmeg—just ½ tsp each—to the batter for warmth. For a subtle kick, swap ½ tbsp of the rum with orange liqueur like Cointreau. I find this balances the boozy notes beautifully while adding complexity. 🌶️
Frosting Variations
Swap the citrus frosting for a cream cheese glaze by mixing 8 oz softened cream cheese, ½ cup butter, and 3 cups powdered sugar. Add 1 tsp vanilla and 2 tbsp rum for cohesion. This adds a tangy contrast that pairs perfectly with the rum's richness.
Boozy Glaze Option
For a decadent drizzle, heat ½ cup heavy cream with 1 cup powdered sugar and 2 tbsp rum until smooth. Thin with 1 tsp lemon juice and drizzle over the cooled cake. This glaze enhances the rum flavor while keeping the cake moist. 💛
Fruit Infusions
Add ½ cup blueberries or raspberries to the batter for bursts of fruitiness. Fold them in gently after mixing the wet ingredients to avoid crushing. The tartness cuts through the rum's sweetness, creating a delightful balance. I recommend using fresh berries for the best texture.
Coffee or Chocolate Twist
For a mocha twist, stir 2 tbsp instant espresso powder into the dry ingredients. Or, fold ½ cup melted dark chocolate into the batter for a rich, fudgy variation. Both options deepen the flavor profile while complementing the rum beautifully. 🍫
Alcohol-Free Adaptation
Replace the rum with 1 cup apple juice or orange juice for a kid-friendly version. Add 1 tsp vanilla extract and ½ tsp almond extract to mimic the rum's depth. The citrus notes still shine through, making it a delicious alternative. 🍎

Frequently asked questions
Can I substitute dark rum for Bacardi Superior in this recipe?
While you can use dark rum, it will change the flavor profile significantly. Dark rum has a deeper, molasses-rich taste that pairs differently with citrus. If you must substitute, reduce the amount to ¾ cup and add 1 tsp extra vanilla extract to balance the flavors. For best results, stick with white rum like Bacardi Superior.
How do I prevent my bundt cake from sticking to the pan?
Grease your bundt pan thoroughly with butter, then dust generously with flour or powdered sugar. Tap out any excess before pouring the batter. For extra insurance, use a baking spray with flour. Let the cake cool in the pan for 15 minutes before inverting—this helps it release more easily.
Can I make this cake ahead of time?
Bake the cake 1 day ahead and store it in an airtight container at room temperature. Frost just before serving to maintain freshness. If storing longer than 3 days, refrigerate the unfrosted cake and bring to room temperature before adding frosting. The flavors actually improve overnight!
Why does my rum cake taste too boozy?
This usually happens when the rum doesn't have time to cook off during baking. To fix it, bake the cake for the full 50-60 minutes and let it cool completely before frosting. The alcohol will evaporate more as it cools. For a less boozy version, reduce the rum to ½ cup and add ½ cup extra milk to maintain moisture.
What's the best way to serve this bundt cake?
This cake shines when paired with strong coffee or black tea to enhance the rum flavors. For a festive touch, garnish with fresh berries or a sprinkle of powdered sugar. Serve slices warm for extra decadence, or at room temperature for a more elegant presentation. It's perfect for birthdays, holidays, or just treating yourself!
