What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and that perfectly moist texture without fuss. Most of these are pantry staples, but a few tips on selecting the best will make all the difference.

• For the Cake Batter:
• All-purpose flour – 2 ½ cups (312g) (I recommend King Arthur Flour for consistent results)
• Baking powder – 2 teaspoons
• Salt – ½ teaspoon
• Unsalted butter – 1 cup (226g), softened (use high-quality butter like Plugrá for richness)
• Granulated sugar – 1 ¾ cups (350g)
• Large eggs – 4, room temperature (brings better volume and texture)
• Vanilla extract – 2 teaspoons (pure vanilla is best)
• Light or dark rum – ½ cup (120ml), plus extra for soaking
• Buttermilk – 1 cup (240ml) (adds tang and keeps the crumb tender)
• For the Rich Amber Glaze:
• Unsalted butter – ½ cup (113g)
• Brown sugar – ¾ cup (150g), packed
• Dark rum – ¼ cup (60ml)
• Vanilla extract – 1 teaspoon

If you prefer a gluten-free option, swapping the all-purpose flour with a 1:1 gluten-free baking flour blend works beautifully. For a dairy-free version, coconut milk can replace buttermilk, and vegan butter substitutes can be used in the glaze. When choosing rum, a quality Caribbean rum like Appleton Estate gives authentic flavor, but any dark rum on hand will do just fine.

Equipment Needed

• 9-inch Bundt pan or tube pan (non-stick preferred)
• Electric mixer (stand or hand) for creaming butter and sugar
• Mixing bowls (medium and large)
• Measuring cups and spoons (accurate measurement is key)
• Rubber spatula for folding and scraping
• Whisk for wet ingredients
• Small saucepan for making the glaze
• Basting brush or spoon for soaking the cake with rum syrup

If you don’t have a Bundt pan, a standard loaf pan works but expect a slightly different shape and bake time. An electric mixer really helps get the batter fluffy, but a vigorous hand whisking can do in a pinch. I’ve found that a silicone spatula makes scraping the bowl effortless, which saves time and mess.

Preparation Method

1. Preheat and Prepare Pan: Heat your oven to 325°F (163°C). Grease your 9-inch Bundt pan thoroughly with butter and dust with flour to prevent sticking. Set aside. (This step is crucial—skip it, and you’ll regret it later!)
2. Mix Dry Ingredients: In a medium bowl, sift 2 ½ cups (312g) all-purpose flour, 2 teaspoons baking powder, and ½ teaspoon salt together. Set aside. (Sifting helps keep the cake light and airy.)
3. Cream Butter and Sugar: Using an electric mixer, beat 1 cup (226g) unsalted butter (softened) and 1 ¾ cups (350g) granulated sugar on medium-high speed until pale and fluffy, about 4-5 minutes. (Don’t rush this; the fluffier, the better!)
4. Add Eggs and Vanilla: Beat in 4 large eggs one at a time, ensuring each is fully incorporated before adding the next. Then mix in 2 teaspoons pure vanilla extract.
5. Alternate Adding Dry Ingredients and Buttermilk: Reduce mixer speed to low. Add the dry flour mixture in three parts, alternating with 1 cup (240ml) of buttermilk, beginning and ending with flour. Mix just until combined—don’t overmix or the cake will be tough.
6. Stir in Rum: Gently fold in ½ cup (120ml) light or dark rum with a spatula until evenly incorporated. The batter will be thick but pourable.
7. Pour and Bake: Transfer batter to your prepared pan, smoothing the top with a spatula. Bake for 60-70 minutes or until a toothpick inserted in the center comes out clean. (Oven temperatures vary, so start checking at 60 minutes.)
8. Prepare Rum Syrup: While the cake bakes, combine ¼ cup (60ml) rum and ¼ cup (50g) granulated sugar in a small saucepan over low heat. Stir until sugar dissolves; keep warm.
9. Soak the Cake: When the cake is out of the oven and still warm (but not hot), poke holes all over the top using a skewer or toothpick. Slowly pour the warm rum syrup over the cake, letting it soak in. Repeat with an additional ¼ cup (60ml) rum if desired for extra moisture.
10. Make the Amber Glaze: In a small saucepan, melt ½ cup (113g) unsalted butter over medium heat. Stir in ¾ cup (150g) packed brown sugar. Bring to a gentle boil and simmer for 2 minutes. Remove from heat and stir in ¼ cup (60ml) dark rum and 1 teaspoon vanilla extract.
11. Glaze the Cake: Once the cake has cooled in the pan for about 20 minutes, invert onto a serving plate. Drizzle the warm amber glaze over the top, allowing it to drip down the sides for a glossy finish.
12. Cool and Serve: Let the cake cool completely before slicing. (Patience is a virtue here—warm cake tends to crumble.) Enjoy with a cup of coffee or a glass of your favorite rum punch!

Cooking Tips & Techniques

First off, don’t skimp on creaming the butter and sugar. That fluffy texture makes all the difference in a moist crumb. I’ve learned the hard way that rushing this step leads to a dense cake, and honestly, that’s just sad.

When adding eggs, make sure they’re at room temperature to blend smoothly and avoid curdling. Also, don’t overmix once you add the flour; overworking the batter tightens the gluten and ruins the tender texture.

One of my favorite tricks is poking holes in the cake right after baking to pour the rum syrup. It sounds simple, but it’s what takes the cake from good to unforgettable by locking in moisture and flavor deep inside.

Watch your oven closely near the end of baking time—every oven is a little different, and you don’t want a dry cake. If the top browns too fast, tent it loosely with foil.

Finally, make the amber glaze while the cake cools. Pouring it warm helps it seep in slightly and gives that irresistible glossy look. Trust me, your guests will be impressed!

Variations & Adaptations

Want to mix things up? Here are a few ideas:

• Fruit-Studded: Fold in ½ cup chopped dried tropical fruits like pineapple, mango, or raisins soaked in rum for extra chew and bursts of flavor.
• Nutty Twist: Add ½ cup chopped toasted walnuts or pecans to the batter for crunch and texture contrast.
• Spiced Rum Cake: Add 1 teaspoon ground cinnamon and ½ teaspoon grated nutmeg to the dry ingredients for a warm, spicy note that pairs beautifully with the rum.
• Non-Alcoholic Version: Replace rum with orange juice or pineapple juice and omit the glaze or swap it with a simple citrus glaze.
• Gluten-Free: Use a 1:1 gluten-free baking flour blend and add 1 teaspoon xanthan gum if your blend doesn’t include it.

I once tried a coconut rum cake version by adding shredded coconut to the batter and swapping regular rum for coconut rum. It was a tropical dream and totally delicious—a great way to personalize the classic!

Serving & Storage Suggestions

This cake is best served at room temperature, allowing all those rich flavors to shine through. I love pairing it with a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence.

For a festive presentation, garnish with fresh mint leaves or toasted coconut flakes. It pairs wonderfully with a cup of strong coffee or a spiced rum cocktail if you want to keep the theme going.

Store any leftovers wrapped tightly in plastic wrap or in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze slices wrapped well in plastic and foil for up to 3 months.

When reheating, gently warm slices in the microwave for 15-20 seconds or in a low oven (300°F/150°C) wrapped in foil to restore that fresh-baked softness. Over time, the rum flavor deepens beautifully, so sometimes a day-old slice tastes even better!

Nutritional Information & Benefits

Each slice (based on 12 servings) contains approximately 350 calories, with 18g fat, 45g carbohydrates, and 4g protein. Keep in mind, this is a celebratory treat with a rich glaze and rum, so enjoy in moderation.
