What You'll Need
You’ll be surprised how few ingredients go into this show-stopping dessert. Most of it comes together with pantry basics and a generous pour of rum.
- Yellow cake mix, This is your shortcut to a tender crumb. Don’t skip it; it’s part of what makes this cake so moist and easy.
- Instant vanilla pudding, Adds extra richness and helps keep the cake incredibly soft. It’s a secret weapon in retro baking.
- Bacardi dark rum, Use the real thing here; it matters. Dark rum gives you that deep, complex flavor that defines this cake.
- Pecans or walnuts, Toasted nuts in the bottom of the pan add texture and flavor. You can skip them if you’re not a nut person, but they’re worth it.
- Butter for the glaze, This creates the silky base for your rum syrup. Don’t use margarine; real butter makes a difference.
Making Bacardi Rum Cake – A Retro Classic, Step by Step
Here’s how to bring this classic together, step by step.
Step 1: Prep Your Pan
Heat your oven to 325°F and grab a 12-cup bundt pan. Grease it generously and dust it with flour, making sure to get into all those ridges. Sprinkle your chopped nuts across the bottom of the pan so they’ll create a nice toasted crust when the cake bakes.
Step 2: Mix the Batter
In a large bowl, combine the cake mix, instant pudding, eggs, cold water, oil, and half a cup of rum. Stir until everything is just combined, don’t overmix. Pour this batter over the nuts in your prepared pan.
Step 3: Bake the Cake
Bake for about 1 hour, or until a toothpick inserted in the center comes out clean. The top should be golden and springy to the touch. Let the cake cool in the pan for about 15 minutes before you start making the glaze.
Step 4: Make the Glaze
While the cake cools, melt your butter in a saucepan over medium heat. Stir in the water and sugar, then let it come to a boil. Keep stirring for about 5 minutes to let it thicken slightly. Remove from heat and stir in the remaining half cup of rum.
Step 5: Poke and Glaze
Once the cake is cool enough to handle, turn it out onto your serving plate. Using a skewer or toothpick, poke holes all over the top and sides, this helps the glaze soak in. Slowly drizzle the glaze over the cake, letting each layer absorb before adding more. This takes patience, but it’s worth every second.
Tips for the Best Results
- Let the cake cool completely before glazing, or the glaze will slide right off. You want it just cool enough to handle, not hot.
- When glazing, work slowly and let each layer soak in. This isn’t a race, the longer you take, the more rum flavor soaks into the cake.
- If your glaze starts to thicken too much as it cools, you can gently rewarm it over low heat to make it pourable again.
- Make sure your bundt pan is really well-greased; this cake has a lot of moisture and can stick if you’re not careful.
- This cake actually tastes even better the next day after the flavors have had time to meld together.
Storage and Make-Ahead Tips
Store
Cover the cake loosely with foil or plastic wrap and keep it at room temperature for up to 3 days. The glaze keeps it incredibly moist, so it won’t dry out quickly.
Freeze
Wrap the whole cake tightly in plastic wrap and then foil; it’ll keep in the freezer for up to 2 months. Thaw it overnight at room temperature before serving.
Reheat
This cake is best served at room temperature, but if you’d like it slightly warm, wrap it in foil and warm it in a 300°F oven for about 10 minutes.

Swaps and Substitutions
- Don’t have dark rum? Spiced rum, coconut rum, or even bourbon will work in a pinch, though the flavor will be different.
- No instant pudding? Just skip it and add an extra egg to keep the cake moist.
- Allergic to nuts? Simply leave them out of the bottom of the pan; the cake is delicious without them.
- Light rum will work, but you’ll lose some of that rich, complex flavor that makes this cake special.
