Ingredients for Rum Cake Recipe with Cake Mix
Pantry staples plus a splash of rum create this bakery-style dessert with ease.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Cake Mix 🎂 | 15 ¼ oz | 1 box, standard size |
| Instant Vanilla Pudding Mix 🥣 | 3.4 oz | 1 small box |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Vegetable Oil 🫒 | ¾ cup | Neutral flavor preferred |
| Dark Rum 🍹 | ¾ cup | Divided for batter and glaze |
| Water 💧 | ½ cup | For cake batter |
| Unsalted Butter 🧈 | ½ cup | Melted for glaze |
| Granulated Sugar 🍚 | 1 cup | For glaze |
| Vanilla Extract 🌿 | 1 tsp | Pure extract recommended |
| Salt 🧂 | ¼ tsp | Fine grain |
| Ground Cinnamon 🌶️ | ½ tsp | Optional for warmth |
The cake mix is your foundation—Betty Crocker or Duncan Hines work perfectly. Instant pudding mix adds moisture and density, so don’t skip it. Use room temperature eggs for better incorporation into the batter. The rum should be dark and full-bodied (think Captain Morgan or Myers’s) for that deep, boozy flavor the intro promises.
No dark rum? Spiced rum works in a pinch, though the flavor will be different. Vegetable oil can be swapped for melted coconut oil if you prefer. For the glaze, brown sugar instead of granulated adds a caramel note. The vanilla extract can be imitation in a pinch, but pure extract delivers superior flavor. Cinnamon is optional but enhances the warmth.
Store the cake in an airtight container at room temperature for up to 5 days. The glaze keeps it moist, and the rum flavor deepens over time. For longer storage, freeze slices for up to 3 months.

Step-by-Step Instructions for Rum Cake With Cake Mix
This method ensures a perfectly moist cake with a rich rum flavor in every bite.
Step 1: Prepare the Cake Batter
Preheat your oven to 325°F and grease a bundt pan thoroughly. In a large mixing bowl, combine the 15.25 oz Yellow Cake Mix, 3.4 oz Instant Vanilla Pudding Mix, 4 whole Large Eggs, 0.75 cup Vegetable Oil, 0.5 cup Water, and 0.5 cup Dark Rum.
Beat the mixture on medium speed for 2 minutes until smooth and well combined. The batter will be thick but pourable. I always scrape down the sides of the bowl halfway through mixing to ensure even incorporation of all ingredients.
Step 2: Bake the Cake to Golden Perfection
Pour the batter evenly into the prepared bundt pan. Smooth the top with a spatula to create an even surface. Place the pan in the preheated oven and bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Check for doneness at the 50-minute mark—overbaking can dry out the cake, and we want to preserve that promised moisture. The top should be golden brown and spring back lightly when touched. If the top browns too quickly, tent loosely with aluminum foil.
Step 3: Prepare the Rum Glaze While Cake Bakes
About 10 minutes before the cake finishes baking, melt the 0.5 cup Unsalted Butter in a saucepan over medium heat. Stir in the 1 cup Granulated Sugar, 0.25 tsp Salt, 1 tsp Vanilla Extract, and the remaining 0.25 cup Dark Rum.
Bring the mixture to a gentle boil, then reduce heat and simmer for 3-4 minutes, stirring occasionally. The glaze should thicken slightly but remain pourable. If using, add the 0.5 tsp Ground Cinnamon at this stage for a warm spice note that complements the rum.
Step 4: Glaze the Cake While Warm
As soon as the cake comes out of the oven, use a long skewer or toothpick to poke holes all over the surface. This allows the glaze to penetrate deeply, ensuring moisture in every slice. Slowly pour about half of the warm glaze over the cake, letting it soak in completely.
After 5 minutes, invert the cake onto a serving plate. Poke a few more holes in the bottom (now the top) and pour the remaining glaze evenly over the surface. Let the cake cool for at least 30 minutes before slicing—this allows the glaze to set and the flavors to meld.
Pro Tips For Making Rum Cake Recipe With Cake Mix
- Preheat the Pan: I learned this the hard way—always preheat your bundt pan in the oven for 5 minutes before adding the batter to prevent sticking and guarantee an even rise.
- Use Quality Rum: Skip the cheap stuff; a good dark rum like Myers’s or Captain Morgan adds depth and richness that budget brands just can’t match.
- Don’t Overmix: After burning three batches, I finally figured out that mixing just until the ingredients come together keeps the cake tender instead of tough.
- Soak It Longer: Sounds weird, but it works: let the baked cake soak up the rum glaze for at least 2 hours—yes, even if you’re impatient like me—so every bite stays moist.
Creative Variations of This Dish
Tropical Coconut Twist
Swap ½ cup water for coconut milk in the batter and add 1 cup shredded coconut to the mix. Replace ¼ cup rum in the glaze with coconut rum for a piña colada vibe. The coconut adds chewy texture and tropical sweetness. 🌴
Spiced Holiday Version
Add 1 tsp ground nutmeg and ½ tsp ground allspice to the batter. For the glaze, include 1 tbsp brown sugar and ½ tsp molasses. This variation tastes like Christmas in every bite, perfect for holiday gatherings.
Chocolate Rum Fusion
Use chocolate cake mix instead of yellow, and add ½ cup chocolate chips to the batter. For the glaze, mix in 2 tbsp cocoa powder with the sugar. The result is a rich, boozy chocolate cake that’s decadent yet simple.
Citrus Rum Brightness
Zest 1 orange and 1 lime directly into the batter for a citrusy lift. Add 2 tbsp orange juice to the glaze for extra brightness. The citrus cuts through the richness, balancing the deep rum flavor beautifully.
Nutty Crunch Addition
Fold 1 cup chopped pecans or walnuts into the batter before baking. Toast the nuts first at 350°F for 8 minutes to enhance their flavor. The crunch contrasts perfectly with the moist cake. 💛
Boozy Coffee Glaze
Replace ¼ cup rum in the glaze with ¼ cup cold brew coffee and add 1 tsp instant espresso powder. The coffee deepens the rum flavor, creating a sophisticated twist that’s perfect for after-dinner dessert.
Frequently Asked Questions
Can I use spiced rum instead of dark rum?
Yes, spiced rum works, though it will give a slightly different flavor profile. Dark rum provides a deeper, more traditional taste, while spiced rum adds warmth and complexity. The choice depends on your preference.
How do I store leftover cake?
Keep it in an airtight container at room temperature for up to 5 days. For longer storage, freeze slices for up to 3 months. The glaze keeps it moist over time.

The pudding mix adds moisture and density to the cake, ensuring a tender crumb. It’s a key ingredient for achieving that bakery-style texture without extra effort.
What if my glaze is too thin?
Simmer it for an extra 1-2 minutes to thicken. If it’s still runny, add 1-2 tablespoons more sugar and heat until dissolved.
