I stumbled upon this incredible recipe at King Arthur Flour, a delightful company nestled in Vermont. A few years back, I had the pleasure of visiting their charming test kitchen and store—what an experience! I adore everything about King Arthur Flour, from their top-notch products to their professional strength extracts and flavorings. While the original recipe captured my heart, I’ve made a few tweaks to achieve what I believe is the perfect balance of flavors. Now, it’s written exactly how I do it, ensuring every bite is pure bliss.
What You’ll Need
A 10- to 12-cup Bundt pan
You’ll need a 10- to 12-cup Bundt pan for this recipe. Bundt cake batters are typically designed for Bundt cake pans because their high moisture and fat content bakes better in them. The pan’s design disperses heat evenly, ensuring the batter rises and bakes uniformly for a perfect cake every time.
All-purpose flour
All-purpose flour ensures a delicate crumb. Bread or cake flour can substitute, but avoid over-mixing. Try whole wheat pastry flour for a wholesome twist.
White granulated sugar
White granulated sugar sweetens and moistens the cake. While substitutes such as honey, maple syrup, agave nectar, stevia, or artificial sweeteners are options, discovering the perfect match for your preferred taste and texture may require some experimentation.
Instant vanilla pudding
Instant vanilla pudding mix enhances texture, flavor, and moistness, creating a luxurious dessert. Avoid sugar-free mixes, which may alter texture. Experiment with banana, caramel, butterscotch, or coconut flavors for a unique twist.
Baking powder
Baking powder serves as a leavening agent, aiding the cake’s rise for a fluffy texture.
Salt
I prefer kosher salt for baking. If you don’t have kosher salt, try table salt (use 50% less), sea salt (use slightly less), or Himalayan pink salt (use a 1:1 ratio).
Unsalted butter
Use unsalted butter to maintain consistency, as the salt content in salted butter varies by brand. If using salted butter, decrease the added salt slightly.
Vegetable oil
Vegetable oil adds moisture to the cake. Canola or safflower oil can be substituted equally without altering the flavor.
Milk
Milk adds moisture and richness to the cake. For substitutions, half-and-half can be used interchangeably with milk in a 1:1 ratio. Dairy-free alternatives like soy and oat milk are preferred for their thicker texture, but be aware that strong-flavored options like coconut may alter the taste. If using heavy cream, dilute it with equal parts water for the right consistency.
Eggs
Eggs bind and structure the cake. For substitutes, use 1 teaspoon baking soda + 1 tablespoon vinegar, ¼ cup plain yogurt, or ¼ cup buttermilk per egg.
Rum
Rum is the heart of this recipe, infusing each cake bite with Caribbean flair. You have the option to use either light or dark rum; dark rum offers a deeper, more complex flavor profile than its milder counterpart. To reduce alcohol content, you can substitute some rum with water. Be sure to adjust the butter-rum flavoring accordingly to maintain the cake’s rich taste.
Vanilla extract
Vanilla extract boosts cake flavor and aroma. Try making your own with Instant Pot for a quick homemade gift in just one week!
Butter-rum flavoring
Butter-rum flavoring enhances buttery and rum notes for a decadent dessert. Available in most supermarkets’ baking aisles or online.
How to Make Caribbean Rum Cake
Get started by preheating your oven to 325°F and giving your Bundt pan a quick spritz with cooking spray. Grab a large mixing bowl and toss in the flour, sugar, pudding mix, baking powder, salt, butter, and oil. Mix until it’s nice and sandy.
Now, crack the eggs into the mix, one by one, and give them a good beating. Pour in the milk and stir until smooth. Here comes the fun part—add in the rum, vanilla, and butter-rum flavoring. Give it all a good stir and then pour the batter into your prepared pan.
Pop it in the oven and let it bake for 50 to 60 minutes, or until a toothpick comes out clean from the center. While it’s baking, whip up the syrup. Toss butter, water, sugar, salt, and, of course, more rum into a saucepan. Bring it to a boil, then let it simmer for 5 to 8 minutes until it’s nice and thick.
Once the cake is out of the oven, poke holes all over it and pour that syrupy goodness while it’s still in the pan. Now, here’s the hard part—let it cool overnight, letting all that syrup soak in. And finally, when you’re ready to indulge, savor every bite of that tropical goodness straight from the islands. Enjoy!
Caribbean Rum Cake (Yum!)
Ingredients
For the cake:
- 2 cups all-purpose flour
- 1½ cups white granulated sugar
- 1 pkg instant vanilla pudding (see Note 1)
- 2 teaspoons baking powder
- 1 teaspoon salt
- ½ cup unsalted butter, softened
- ½ cup vegetable oil
- ½ cup milk, at room temperature
- 4 large eggs
- ½ cup rum, plain or spiced (see Note 2)
- 2 teaspoons vanilla extract
- ¼ teaspoon butter-rum flavoring (see Note 3)
For the syrup:
- ½ cup unsalted butter, 1 stick
- ¼ cup water
- 1 cup white granulated sugar
- ¼ teaspoon salt
- ½ cup rum, plain or spiced (see Note 2)
- ½ teaspoon vanilla extract
Instructions
- Preheat oven to 325 F.
- In a large mixing bowl, place flour, sugar, pudding mix, baking powder, salt, butter, and oil and mix at medium speed until everything is thoroughly incorporated and the mixture looks like sand.
- Beat in the milk. Add the eggs one at a time, beating well between each addition. Scrape the bowl thoroughly and beat briefly to incorporate.
- Stir in the rum, vanilla, and butter-rum flavoring.
- Prepare Bundt pan with cooking spray. Pour batter into prepared pan and spread it level with a spatula
- Bake for 50- to 60-minutes. Test for doneness using a skewer, toothpick, or dry piece of ucooked spaghetti. It should come out clean when inserted into the center area of the cake. Do not overbake. Remove cake from the oven. Leave the cake in the pan while you prepare the syrup.
- In a medium-size saucepan, combine the butter, water, sugar, salt, and rum. Bring to a rapid boil then reduce to a simmer to cook—without stirring—for 5 to 8 minutes, until the syrup thickens slightly. Remove from the heat and stir in the vanilla.
- Using a long skewer or similar, poke holes all over the cake. Pour about 1/4 cup syrup over the cake, while it is still in the Bundt pan. Allow the syrup to soak in, then repeat again and again, until all the syrup has been absorbed. See NOTE 4.
- Cover the pan loosely with plastic wrap, allowing the cake to sit overnight at room temperature to cool completely and for the syrup to soak into all of the cake.
- When ready to serve, invert the cake over a serving plate. If it won't loosen to fall out of the pan easily, do not force it. Instead, tent the pan with foil, place it in the oven on the bottom rack and turn it on to 350 F. for 10 minutes. Remove the cake from the oven, and now tip it onto the serving plate. Serve and enjoy!
- If any of this amazing cake remains, put it in a cake saver OR wrap it securely in plastic wrap, storing it at room temperature for 2 to 3 days. You may confidently freeze for longer storage, up to one month.

Hi Mary, Very excited to try this, but I’ve been to 5 grocery stores & can only find Rum Extract. No one has Rum Butter. Will this work? Thx.
You can try to combine rum extract with butter extract. Use more rum extract, try a 3:1 ratio of rum to butter. Let us know how it works!
