Ingredients for bacardi gold rum cake
Eight ingredients for a showstopper cake—rum-infused layers and caramel glaze guaranteed to impress.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Unsalted Butter 🧈 | 1 cup | Room temperature, not melted |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Vanilla Extract 🌿 | 2 tsp | Pure vanilla preferred |
| Bacardi Gold Rum 🍹 | 1 cup | For soaking syrup |
| Powdered Sugar 🍚 | 2 cups | For glaze |
| Heavy Cream 🥛 | ½ cup | Cold, for glaze |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Butter 🧈 | ¼ cup | Melted for glaze |
| Vanilla Ice Cream 🍦 | 1 cup | For serving (optional) |
The Bacardi Gold Rum is non-negotiable here—its smooth, caramel notes are what make this cake special. Grab the bottle from a liquor store (not the mini bottles at the grocery store checkout) for the best flavor. The butter should be at room temperature but not melted—press it with your finger to test. As for flour, King Arthur or Gold Medal brands work best for a tender crumb. If you're baking in a dry climate, add an extra tablespoon of milk to the batter for extra moisture.
No rum? Dark corn syrup or molasses at half the amount will mimic the caramel depth, though the boozy flavor will be missing. Short on powdered sugar? Sift granulated sugar—it won’t be as smooth, but it’ll work in a pinch. The glaze needs cold heavy cream to set properly, so take it out of the fridge 10 minutes before using. For a nutty twist, fold in 1 tbsp chopped toasted pecans into the glaze. The cake layers can be baked ahead and stored at room temperature for up to 2 days before assembling.
This cake is best served warm with a scoop of vanilla ice cream—trust me, the contrast is magic. Leftovers keep 3 days at room temperature covered tightly, or 1 week refrigerated. The glaze sets as it cools, so don’t rush slicing. For a crowd, double the glaze recipe—it’s that good. If you’ve got extra rum, drizzle a little over the top before serving for extra wow factor.

Step-by-step instructions for Bacardi Gold rum cake
This rum-soaked cake delivers rich moisture and a caramelized glaze that'll make everyone ask for seconds.
Mix Dry Ingredients for Light Texture
In a medium bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, and 0.5 tsp salt. Sift the mixture twice to aerate it—this prevents dense cake. Set aside while you prep the wet ingredients. The flour should look fluffy and evenly distributed with no lumps.
I like to use a fine-mesh sieve for this step because it creates tiny air pockets that help the cake rise properly. Don't skip sifting—it makes a noticeable difference in the final texture. Keep the bowl nearby as you'll need it in the next step.
Cream Butter and Sugar Until Fluffy
In a large mixing bowl, combine the 1 cup unsalted butter (at room temperature) and 2 cups granulated sugar. Beat with an electric mixer on medium speed for 3-4 minutes until light and fluffy. You'll see the mixture nearly double in volume and turn pale—this incorporates air that helps create a tender crumb.
Here's the thing—room temperature butter is crucial. If it's too cold, it won't cream properly; if too soft, it'll turn greasy. Press the butter between your fingers—it should hold its shape but still be pliable. Add the 4 whole large eggs, one at a time, beating well after each addition until fully incorporated.
Combine Wet Ingredients with Rum
In a small bowl, whisk together the 1 cup Bacardi Gold Rum, 2 tsp vanilla extract, and 1 tbsp lemon juice. The lemon brightens the rum flavor and balances the richness. Gradually add this mixture to the butter-sugar-egg combination, alternating with the dry ingredients in 3 additions. Start and end with the dry ingredients.
Mix on low speed just until combined—you don't want to develop gluten. The batter should be thick but pourable. If it looks too stiff, add 1-2 tablespoons of milk (not listed, but common substitution) to loosen it. The rum will give the cake its signature moisture and subtle caramel notes.
Bake Until Golden and Springy
Pour the batter into a 9x13-inch baking pan lined with parchment paper. Smooth the top with a spatula. Bake at 350°F for 35-40 minutes until the top is golden brown and a toothpick inserted in the center comes out clean. The cake should feel springy to the touch when pressed gently in the center.
Don't overbake—rum cakes dry out quickly. I pull mine when the edges are set but the center still has a slight jiggle. Let it cool in the pan for 10 minutes before transferring to a wire rack. This prevents cracking as it cools completely.
Prepare the Rum Caramel Glaze
While the cake cools, make the glaze by melting the 0.25 cup butter in a small saucepan over low heat. Remove from heat and whisk in the 2 cups powdered sugar and 0.5 cup heavy cream until smooth. Add the 1 tbsp lemon juice and 1 tbsp Bacardi Gold Rum (save a splash for brushing). The glaze should be thick but pourable.
Once the cake is completely cool, spread half the glaze over the top. Brush the remaining glaze over the sides, letting it drip down naturally. For extra shine, drizzle the reserved rum over the top and let it soak in for 10 minutes before serving. The glaze should be glossy and slightly sticky to the touch.
Serve with Vanilla Ice Cream (Optional)
Slice the cake into 8 equal pieces using a sharp knife dipped in hot water. This ensures clean cuts. Serve immediately with a scoop of 1 cup vanilla ice cream on the side for the ultimate indulgence. The warm cake contrasts beautifully with the cold ice cream, balancing the rich flavors.
The cake keeps well at room temperature for 2 days or in the fridge for up to 4 days, though it's best enjoyed fresh. If storing, cover tightly with plastic wrap to preserve moisture. The rum flavor actually intensifies as it sits, making leftovers even more delicious.
Pro Tips For Making Bacardi Gold Rum Cake
- MEASURE BUTTER COLD (NOT SOFT): I learned this the hard way—when butter’s too warm, the cake turns greasy instead of tender. Take it straight from the fridge, cut it into chunks, and let it sit just until it’s pliable (about 10 minutes). No food processor? Use your fingers to work it into the sugar until it’s crumbly but holds shape.
- SIFT DRY INGREDIENTS TOGETHER: Skimping on this step means lumpy cake. Mix flour, baking powder, and salt in a bowl, then sift them directly into your mixing bowl with the wet ingredients. The extra aeration makes the texture lighter, especially when layered with rum-soaked syrup. (Yes, even if you’re impatient like me.)
- BAKE UNTIL TESTER COMES OUT CLEAN: The cake will look done before it is—don’t trust the edges. Insert a tester into the center; if it pulls out with a few moist crumbs (not wet batter), pull it out. Overbaking dries out the rum flavor and makes the layers tough. A toothpick test works too, but I’ve seen it fool me before.
- SOAK LAYERS QUICKLY (NOT TOO SOON): Pour the rum syrup right after removing the cake from the oven while it’s still warm. Let it cool for 10 minutes first—if you soak it piping hot, the butter melts unevenly and the syrup pools. Spread evenly, then let it absorb for 5 minutes before stacking layers. (Your future self will thank you.)
Pro cooking tips for this recipe
Rum Soaking Secrets
Don’t just pour rum into the batter—this cake gets its magic from soaking layers while baking. After mixing, spread the batter evenly in your pan, then poke holes with a fork (about ½-inch apart) to create channels for the rum to seep through. I use a skewer for precision—it makes clean holes without tearing the batter. 🍹
For extra moisture, brush the batter with 2 tbsp Bacardi Gold Rum right after pouring it into the pan. This creates a rum-infused steam during baking, ensuring every bite is boozy and tender. If you’re nervous about alcohol content, let the cake bake uncovered for the first 20 minutes to evaporate some of the alcohol before covering with foil.
Glaze Consistency Control
The glaze should be thick but pourable—like honey. If it’s too runny, whisk in 1-2 tbsp powdered sugar until it coats the back of a spoon. For a mirror-gloss finish, chill the glaze for 10 minutes before applying. I use a pastry brush to spread it evenly, then let it drip naturally over the sides. Pro tip: Add a pinch of salt to the glaze to enhance the rum flavor and balance sweetness.
For a professional crackle, brush the glaze in thin layers—thick application can make it pool unevenly. Work quickly once the glaze is ready, as it sets fast. If you have leftover glaze, store it in an airtight container for up to 3 days—it’s perfect for drizzling over other desserts like pancakes or ice cream.
Butter Temperature Matters
Room-temperature butter is non-negotiable—it creams properly and creates a light, airy crumb. To test, press a pat between your fingers: it should hold its shape but still be pliable. If your kitchen is cold, let the butter sit on the counter for 1-2 hours before starting. For a shortcut, microwave it in 10-second bursts until just soft (not melted). Never use melted butter—it’ll make the cake dense. 🧈
If your butter is too soft, chill the mixing bowl in the freezer for 5 minutes before creaming. This helps stabilize the fat, preventing greasiness. I also recommend using European-style butter (like Plugrá) for higher fat content—it yields a richer, more flavorful cake.
Baking Time Precision
Rum cakes bake faster than traditional cakes because the alcohol lowers the moisture content slightly. Start checking for doneness at 30 minutes—the edges should pull away from the pan, and a toothpick inserted in the center should come out with moist crumbs (not wet batter). Overbaking is the #1 mistake—it turns the cake dry and crumbly. 🔥
For even baking, rotate the pan halfway through (at 20 minutes). If your oven runs hot, reduce the temperature to 325°F. I test doneness by pressing the center gently—it should spring back slowly, not bounce back immediately. Let the cake cool in the pan for 10 minutes before transferring to a wire rack to prevent cracking.
Serving Like a Pro
Slice the cake while it’s still slightly warm—this ensures clean cuts and prevents crumbling. Dip your knife in hot water between slices for a smooth finish. For a restaurant-worthy presentation, dust the top with powdered sugar or sprinkle with toasted coconut flakes. Serve with a drizzle of warmed rum sauce (simmer ½ cup heavy cream, 2 tbsp powdered sugar, and 1 tbsp rum for 3 minutes).
Pair with vanilla ice cream or whipped cream for contrast—cold cream balances the warm, boozy cake. For a cocktail twist, serve with a Bacardi Gold Rum cocktail (like a Rum Old Fashioned) on the side. The flavors complement perfectly, making it feel like a tropical escape. 🍹

Frequently asked questions
Can I substitute Bacardi Gold Rum with another type?
While Bacardi Gold Rum is ideal for its smooth caramel notes, you can use dark rum (like Appleton Estate) or spiced rum (like Captain Morgan) in a pinch. For a non-alcoholic version, replace it with 1 cup apple juice or dark corn syrup—just reduce the vanilla extract to 1 tsp to balance the flavor. The boozy depth will be missing, but the moisture will still work.
Why does my rum cake turn out dry?
Overbaking is the #1 culprit—rum cakes bake faster than regular cakes. Pull it when a toothpick comes out with moist crumbs (not wet batter). Another trick: brush the batter with 2 tbsp rum before baking to add moisture. If your kitchen is dry, increase the butter to 1.25 cups for extra richness.
How do I make this cake ahead of time?
Bake the cake 1 day ahead and store it at room temperature wrapped tightly in plastic. The flavors deepen overnight! For the glaze, make it fresh 2 hours before serving—it sets best when applied to a slightly warm cake. Reheat slices in the oven at 300°F for 5 minutes to restore moisture before serving.
Can I layer this cake with cream cheese frosting?
Swap the rum glaze for a vanilla cream cheese frosting (mix 8 oz cream cheese, ½ cup butter, 3 cups powdered sugar, and 1 tsp vanilla). Assemble layers with rum-soaked sponge cake and a thin rum syrup layer (mix ½ cup rum with ½ cup sugar and 2 tbsp water, heated until dissolved).
What’s the best way to store leftovers?
Keep the cake at room temperature in an airtight container for up to 3 days—the rum flavor actually improves! For longer storage, refrigerate for 1 week (bring to room temp before serving). Freeze slices wrapped tightly for 1 month, but thaw overnight in the fridge to preserve texture.
