Ingredients for bacardi rum cake recipe cake mix with pudding in it
Fourteen simple ingredients transform into a decadent rum cake with no-fuss streusel topping.
| Ingredient | Amount | Notes |
|---|---|---|
| Vanilla Cake Mix 🍰 | 1 box | Standard yellow cake mix |
| Bacardi Rum (or any dark rum) 🍹 | ½ cup | 151-proof preferred for bold flavor |
| Instant Vanilla Pudding Mix 🍮 | 3 tbsp | Small box (3.4 oz) for 2 servings |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat for richness |
| Milk 🥛 | ½ cup | Whole milk preferred |
| All-Purpose Flour 🌾 | ½ cup | For streusel texture |
| Light Brown Sugar 🍚 | ½ cup | Packed for moisture |
| Old-Fashioned Rolled Oats 🥣 | ½ cup | Blended into flour for texture |
| Vanilla Extract 🌸 | 1 tbsp | Pure vanilla for depth |
| Ground Cinnamon 🌿 | 1 tsp | For streusel warmth |
| Salt 🧂 | ¼ tsp | Kosher or sea salt |
| Baking Powder 🍞 | ½ tsp | For extra lift |
The rum is non-negotiable here—Bacardi 151 gives the boldest flavor, but anything dark works. If you're worried about alcohol content, bake it longer (25-30 minutes) to burn off the fumes. Trader Joe's and Walmart usually have affordable bottles. The cake mix? Grab the basic vanilla—Betty Crocker or Pillsbury are foolproof. For the pudding mix, Jell-O or Betty Crocker both work, but check the box size—you only need 3 tablespoons of powder, not the whole thing.
No rum? Substitute with 1/4 cup orange juice plus 1 tsp vanilla extract—it won’t be the same, but it’ll still taste amazing. Running low on butter? Coconut oil works in a pinch, but it’ll be slightly less rich. The streusel oats can be swapped for crushed graham crackers if that’s what you’ve got. Fresh vanilla extract is worth the splurge here—Nielsen-Massey or McCormick are reliable brands. And if you’re feeling fancy, add a pinch of nutmeg to the streusel for extra warmth.
This cake keeps beautifully—3-4 days at room temperature wrapped in foil, or 1 week in the fridge. For leftovers, slice and reheat in the microwave for 20 seconds with a damp paper towel over the top. The streusel stays crisp even after reheating, so it’s perfect for breakfast cake or dessert. Double the recipe? It bakes in the same pan for 5-7 minutes longer—just watch closely after 20 minutes.
Why You'll Love This Recipe
- Pantry Magic: Mixing dry ingredients is my kind of cooking—just dump the cake mix, stir in the rum, and fold in that pudding mix. No measuring cups, no stress, just a bowl and a whisk.
- Moisture Bomb: The pudding swirled into the batter? It keeps this cake dangerously tender for days. That first bite—rich, rum-soaked, with a velvety pudding pull—makes it my go-to dessert.
- Party in a Box: Bring this to a potluck, a birthday, or even a "just because" night. The rum aroma announces itself before you even slice it, and it’s the kind of cake that disappears fast.
- Budget Booster: You’re using cake mix, pudding mix, and rum you already own. The butter and eggs stretch the cost, and leftovers? They’re even better the next day—if they last that long.
Step-by-step instructions for Bacardi rum cake recipe
This cake delivers unbeatable moisture and a perfect balance of boozy flavor and crunchy streusel.
Prep the Streusel Topping
In a small bowl, combine the 0.5 cup all-purpose flour, 0.5 cup light brown sugar, 0.5 cup old-fashioned rolled oats, 1 tsp ground cinnamon, 0.25 tsp salt, and 0.5 tsp baking powder. Mix until evenly distributed—you want a crumbly, sand-like texture that will create that perfect crunchy topping.
Here's the thing—don't pulse this in a food processor or you'll end up with a paste. Use your fingers to work the mixture until it's just combined. Set this aside while you prep the cake batter. This step ensures your streusel stays chunky and flavorful rather than turning into a dense layer.
Mix the Cake Batter
In a large mixing bowl, whisk together the 1 box vanilla cake mix, 3 tbsp instant vanilla pudding mix, 2 whole large eggs, 0.5 cup melted unsalted butter, 0.5 cup milk, 1 tbsp vanilla extract, and 0.5 cup bacardi rum. Mix on medium speed for 2 minutes until completely smooth and all the dry ingredients are fully incorporated.
I like to let the rum infuse the batter for 10 minutes before adding the streusel. This gives the alcohol time to mingle with the other ingredients, enhancing that rich, caramel-like flavor. The pudding mix here is the secret weapon—it adds extra moisture and helps create that ultra-tender crumb.
Combine and Bake
Gently fold the streusel topping into the cake batter using a spatula, mixing just until the streusel is evenly distributed. Pour the batter into a 9-inch round cake pan that's been lightly greased and lined with parchment paper. The batter will be thick but still pourable—don't overmix or you'll lose that perfect texture.
Bake in a preheated 350°F oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean. The cake should have a golden top with a slightly crispy streusel layer. If you see the edges browning too quickly, tent the cake with foil to prevent over-browning while it finishes baking.
Cool and Serve
Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. This short rest prevents the cake from cracking as it cools. The cake will be moist and rich with a perfect balance of boozy flavor from the rum and that crunchy streusel on top.
For the best experience, serve the cake at room temperature. The flavors deepen as it cools, and the streusel maintains its perfect crunch. You can dust with powdered sugar or serve with a scoop of vanilla ice cream if you're feeling extra indulgent. This cake is best enjoyed within 2-3 days for maximum moisture and flavor.
Pro Tips For Making Bacardi Rum Cake Recipe Cake Mix With Pudding In It
- Whisk the Pudding First: Mix the instant vanilla pudding with the milk before adding it to the cake batter—it dissolves smoother and avoids lumps. I learned this the hard way after scraping dried pudding chunks out of my cake for the third time.
- Measure Rum Cold: Use chilled rum straight from the fridge—it blends into the batter more evenly and doesn’t evaporate as fast while mixing. Warm rum adds an alcohol-heavy aroma that fades into the background instead of popping through.
- Grease the Pan Hot: Warm your cake pan in the oven for 2 minutes before adding butter and flour, then coat it while it’s still hot. This guarantees the cake won’t stick, even if you’re impatient and skip the parchment paper (we’ve all been there).
- Bake Until Slightly Under: Pull the cake out when the center still jiggles just a little—it’ll firm up as it cools. Overbaking turns this moist rum-pudding cake into a dry brick, and no one’s coming back for seconds then.
Best sauces and condiments for this bacardi rum cake recipe cake mix with pudding in it
Rum Caramel Drizzle
Elevate your rum cake with a homemade rum caramel drizzle that ties all the flavors together. Simmer ½ cup granulated sugar with ¼ cup heavy cream and 2 tbsp Bacardi rum until it reaches 235°F on a candy thermometer. Let cool slightly, then drizzle over the cake just before serving. The caramel’s buttery sweetness contrasts beautifully with the rum’s warmth. 🍯
Whipped Cream with Rum
Lightly infuse your whipped cream with rum for an extra layer of boozy indulgence. Whip 1 cup heavy whipping cream with 2 tbsp powdered sugar until soft peaks form, then fold in 1 tbsp Bacardi rum. Pipe or dollop onto the cake for a cloud-like finish. For extra flair, dust with toasted coconut flakes or a pinch of cinnamon. 🥛
Spiced Rum Glaze
A spiced rum glaze adds depth and shine to your cake. Mix ½ cup powdered sugar, 2 tbsp spiced rum (like Captain Morgan), and 1-2 tbsp milk until smooth. Drizzle over the cake while still slightly warm for a glossy, sticky finish. The spices complement the rum’s caramel notes perfectly. 🌶️
Vanilla Bean Ice Cream
Serve slices of rum cake with a scoop of homemade vanilla bean ice cream to balance the richness. The cold creaminess cuts through the cake’s density, while the vanilla enhances the rum’s natural sweetness. For a pro touch, swirl a little rum caramel into the ice cream before scooping. 🍦
Chocolate Ganache
For chocolate lovers, a dark chocolate ganache adds a sophisticated contrast. Melt ½ cup dark chocolate chips with ¼ cup heavy cream, then drizzle over the cake. Let it set slightly before serving. The bitterness of the chocolate balances the cake’s sweetness, creating a harmonious bite. 🍫
Citrus Zest Garnish
Brighten up your rum cake with a sprinkle of lemon or orange zest** on top. The citrus notes awaken the rum’s flavors and add a refreshing pop of color. Use a fine grater for a delicate finish, and pair it with a dusting of powdered sugar for extra elegance. 🍋

Frequently asked questions
Why does this recipe use instant pudding mix instead of homemade pudding?
Instant pudding mix adds extra moisture and richness without requiring extra steps. The powder dissolves completely into the batter, creating a tender crumb that stays moist for days. Homemade pudding would make the batter too thick and could affect the cake's texture.
Can I make this cake without alcohol?
Yes! Replace the 0.5 cup Bacardi rum with 1/4 cup orange juice plus 1 tsp vanilla extract. The cake will still be delicious, though the boozy caramel notes will be missing. For extra flavor, add 1 tsp almond extract to mimic rum's depth.
How do I prevent the streusel from burning before the cake is done?
Tent the cake with aluminum foil after 20 minutes of baking if the streusel starts browning too quickly. This keeps the center cooking while protecting the top. Alternatively, reduce your oven temperature to 325°F for the last 10 minutes of baking.
Can I use a different cake mix flavor?
While vanilla is ideal, you can try yellow or spice cake mix for variation. Avoid chocolate mixes—they'll clash with the rum's sweetness. If using spice, reduce the streusel cinnamon to 0.5 tsp to avoid overpowering flavors.
What's the best way to store leftovers?
Wrap slices tightly in plastic wrap and store at room temperature for 2 days or refrigerate for up to 5 days. For longer storage, freeze slices for 3 months. Reheat in the microwave for 15-20 seconds with a damp paper towel to restore moisture.
