Simple ingredients that pack a boozy punch—rum, cake mix, and pudding transform into a showstopper dessert.
| Ingredient | Amount | Notes |
|---|---|---|
| Bacardi Superior Rum 🍹 | ½ cup | Dark or gold variety preferred |
| Vanilla Cake Mix 🍞 | 1 box | 15.25 oz box preferred |
| Instant Vanilla Pudding Mix 🥄 | 1 box | 1.75 oz box, vanilla flavor |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for streusel |
| Granulated Sugar 🍚 | ½ cup | For streusel topping |
| All-Purpose Flour 🌾 | ½ cup | For streusel topping |
| Chocolate Chips 🍫 | ½ cup | Semi-sweet preferred |
| Milk 🥛 | 1 cup | Whole milk preferred |

The rum is non-negotiable here—Bacardi Superior delivers that perfect balance of warmth without overpowering. Grab the dark or gold variety from Trader Joe's or Total Wine if you want to splurge, but any good-quality rum works. The cake mix? Vanilla is ideal—it lets the rum shine. For the pudding mix, instant is key—it thickens better when baked. Pro tip: Buy extra rum. You'll want more than you think, and it keeps forever. The chocolate chips? Semi-sweet is classic, but dark chocolate chips add a sophisticated twist.
No rum? Substitute with 1/2 cup orange juice plus 1 tsp vanilla extract—it won't be the same, but it'll still taste amazing. Out of vanilla cake mix? Chocolate or spice cake mix works too, just reduce the rum by 1/4 cup to balance flavors. The streusel topping can be made ahead—just store it in the fridge until ready to use. For a richer cake, add 1/4 cup sour cream to the batter. The baking powder is crucial—it lightens the cake without making it dry. If you're feeling fancy, swap the chocolate chips for toasted pecans or white chocolate chips.
This cake keeps beautifully—3-4 days at room temperature wrapped in plastic, or 1 week in the fridge. For parties, assemble it a day ahead and refrigerate. Reheat slices in the microwave for 10-15 seconds to restore that gooey pudding layer. The streusel topping freezes well too—just thaw before using. I always make a double batch. One for now, one for later—because this cake disappears faster than you can say 'second slice.'

Step-by-step instructions for boozy rum cake magic
Here's how to create a decadently moist rum cake with a perfect streusel crown—every bite packed with flavor!
👨🍳 Step 1: Mix the Cake Batter Like a Pro
In a large mixing bowl, combine the 1 box vanilla cake mix, 2 whole large eggs, 1 cup milk, and 0.5 cup vegetable oil. Use a hand mixer on medium speed for 2 minutes until the batter is completely smooth and no dry spots remain. This ensures even distribution of ingredients for maximum moisture.
In a separate small bowl, whisk together the 0.5 cup Bacardi Superior Rum and 1 box instant vanilla pudding mix. The rum will infuse the pudding mix, creating that signature boozy flavor throughout the cake. Gradually pour this rum-pudding mixture into the cake batter while mixing on low speed for another 30 seconds until fully incorporated. The batter should be thick but pourable—like a rich, velvety cake batter.
🍳 Step 2: Prepare the Streusel Topping
In a medium bowl, cut the 0.5 cup unsalted butter into small cubes and use a fork or your fingers to work it into the 0.5 cup granulated sugar until it resembles coarse crumbs. Add the 0.5 cup all-purpose flour, 1 tsp ground cinnamon, and 0.25 tsp salt, mixing until everything is evenly combined. The streusel should hold its shape when pressed but still crumble easily between your fingers.
Fold in the 0.5 cup chocolate chips using a spatula, ensuring they're evenly distributed. This streusel topping is what creates that magical caramelized crown when baked. If the mixture seems too dry, add 1-2 teaspoons of milk to help it bind together—just enough to hold its form without becoming sticky.
🥘 Step 3: Assemble and Bake the Cake
Preheat your oven to 350°F and grease a 9x13-inch baking dish thoroughly with butter or non-stick spray. Pour the cake batter evenly into the prepared pan, spreading it out to the edges. Sprinkle the streusel topping evenly over the batter, pressing down gently with your fingers to create a continuous layer. The streusel should cover the entire surface—this is where the magic happens!
Bake for 35-40 minutes until a toothpick inserted in the center comes out clean and the streusel topping is golden brown with bubbly spots. The cake should be springy to the touch and pull away slightly from the sides of the pan. Here's the thing—I like to tent the pan with foil after 25 minutes to prevent the streusel from over-browning while the cake finishes baking underneath.
⏰ Step 4: Cool and Serve for Maximum Moisture
Remove the cake from the oven and let it cool in the pan for 10 minutes before transferring it to a wire rack. The residual heat will continue to set the cake while preventing it from becoming soggy. Here's where patience pays off—allow the cake to cool completely for at least 1 hour before slicing. This resting period lets the flavors meld and the moisture distribute evenly throughout each slice.
Once fully cooled, cut into 12 equal squares and serve. Each bite should deliver a perfect balance of moist, rum-infused cake with a crunchy, caramelized streusel crown. For extra decadence, dust with powdered sugar or drizzle with a simple rum glaze made from 2 tablespoons powdered sugar and 1 tablespoon rum. This cake keeps well at room temperature for 3 days or refrigerated for up to 5 days, making it perfect for special occasions!
Pro Tips For Making Bacardi Rum Cake Recipe Cake Mix With Pudding In It
- MIX THE PUDDING FIRST: Mix the instant vanilla pudding with the rum before adding it to the batter—this lets the alcohol bloom the flavors instead of just sitting as a boozy afterthought. I used to dump it in dry, and the cake always tasted like it was hiding its liquor.
- LET THE BUTTER SOFTEN RIGHT: Take the butter out of the fridge 30 minutes before mixing—room temp butter blends smoother and doesn’t turn your cake greasy. I learned this the hard way after a batch split like a sad soufflé.
- DON’T OVERMIX THE BATTER: Stop folding in the pudding mixture as soon as it’s just combined—overmixing makes the cake dense and chewy, not light and fluffy. Two turns of a spatula is all you need; your future self will thank you.
- BAKE UNTIL THE CENTER HITS 205°F: The pudding in this cake makes it trickier to judge doneness—use a thermometer and wait for that internal temp. I used to pull it out at 190°F, and it’d collapse like a wet paper bag. Patience pays off.
Common mistakes when making perfect results
Overmixing the Batter
I’ve seen this happen more times than I can count—someone mixes the cake batter until it’s so dense it could stand on its own. The vanilla cake mix contains baking powder, and overmixing develops gluten, which makes the cake tough instead of tender. Mix just until the 2 minutes are up, and no dry spots remain. The batter should be smooth but still pourable, not stiff or elastic. 💫
Skipping the Rum-Pudding Mix Step
If you just dump the rum into the batter without first mixing it with the pudding mix, you’ll end up with a cake that’s moist but lacks that signature boozy depth. The pudding mix absorbs the rum and distributes it evenly throughout the batter, ensuring every bite has that rich, caramelized rum flavor. Don’t skip this step—it’s what makes this cake special!
Uneven Streusel Distribution
An uneven streusel topping can make your cake look messy and taste inconsistent. Press the streusel down gently but firmly to create a continuous layer over the batter. If you skip this step, the streusel might clump in some areas and leave gaps in others, leading to dry spots or undercooked cake underneath. Think of it like frosting a cake—smooth and even is key. 🍹
Baking Without Tenting
If you bake the cake for the full 35-40 minutes without tenting it with foil after 25 minutes, the streusel topping can burn before the cake is fully cooked. The streusel caramelizes quickly, but the cake underneath needs time to finish baking. Tenting with foil keeps the streusel from over-browning while allowing the cake to set properly. Trust me, this is a game-changer for a perfect finish.
Cutting Too Soon
I know the cake looks irresistible, but cutting into it too soon is a cardinal sin. The cake needs at least 1 hour to cool completely before slicing. If you cut it too early, the pudding layer will leak out, making the cake soggy and the streusel soggy too. Patience here ensures clean slices with that perfect balance of textures and flavors.
Using the Wrong Rum
Not all rum is created equal. If you use a cheap, low-quality rum, the flavor will be weak and taste like alcohol rather than the warm, caramelized notes you want. Stick with Bacardi Superior (dark or gold) for that perfect balance. If you’re out of rum, don’t substitute with just any liquor—orange juice plus vanilla extract is the closest you’ll get, but it won’t be the same. 🍫

Frequently asked questions
Can I use a different type of cake mix for this rum cake?
Yes! While vanilla cake mix works best, you can swap it for chocolate or spice cake mix. If using chocolate, reduce the rum by 1/4 cup to balance flavors. For spice mixes, add 1/2 teaspoon extra cinnamon to the streusel to enhance warmth. The pudding layer will still create that signature moisture, but the cake's base flavor will change.
How do I make this cake more boozy without adding extra rum?
For a stronger rum flavor without extra liquid, soak the streusel topping in 2 tablespoons rum for 10 minutes before baking. Alternatively, replace 1/4 cup milk in the batter with rum. The pudding mix already absorbs rum well, so these tweaks amplify the boozy notes without altering the texture.
Can I make this cake in a different pan size?
For a 9-inch round pan, reduce baking time to 30-35 minutes and tent with foil at 20 minutes. For an 8x8-inch pan, bake 25-30 minutes and adjust streusel quantity to 1/2 cup total. Always check doneness with a toothpick—overbaking dries out the pudding layer.
Why does my cake taste dry after baking?
Dryness usually means overbaking or under-mixing. Ensure you bake until a toothpick comes out clean (not dry), and mix the batter for the full 2 minutes. For extra moisture, brush the cooled cake with 1 tablespoon rum mixed with 1 tablespoon melted butter before serving.
Can I freeze this rum cake?
Yes, but freeze it fully assembled (without slicing) for best results. Wrap tightly in plastic wrap, then foil, and freeze for up to 3 months. Thaw overnight in the fridge. Reheat slices in the microwave for 10-15 seconds to revive the pudding layer. The streusel stays crispy when reheated properly!
