Ingredients You’ll Need

This recipe uses pantry staples paired with a splash of dark rum to create a cake that’s luxurious and moist with every bite.

Cake flour is essential for a tender crumb. It’s lower in protein than all-purpose flour, yielding a softer, more delicate cake. You can substitute all-purpose flour if needed, but the texture will be slightly denser.

Baking powder gives the cake a gentle rise, ensuring it bakes up fluffy and not flat. Be sure your baking powder is fresh for proper leavening.

Salt balances the sweetness and enhances flavor. Don’t skip it. It also plays a role in gluten formation, so measure accurately.

Granulated sugar sweetens and helps create that golden crust. Stick with white sugar here for clean flavor and structure.

Unsalted butter brings richness and structure, while letting you control the salt level. Soften it at room temperature first for the creaming step.

Vegetable oil keeps the cake extra moist, even after a day or two. You can swap it with canola oil or light olive oil if needed.

Eggs and egg yolks deliver structure and act as emulsifiers. Room temperature eggs whisk together more easily and trap air, which helps the cake rise.

Vanilla extract adds cozy warmth and enhances the rum’s bold notes. Pure vanilla is best for clean, natural flavor.

Dark rum is the star. Its deep, caramel-molasses flavor pairs beautifully with the buttery cake. Use a quality rum for best results. Spiced rum can be used for a twist.

Whole milk adds moisture, tenderness, and richness. Avoid low-fat milk, which won’t provide the same full mouthfeel.

The rum syrup glaze made with butter, sugar, and dark rum is poured over the warm cake, soaking into every crevice for maximum moisture and flavor.

Variations

This versatile Moist Rum Cake can be tweaked easily to match different diets, budgets, or flavor preferences without compromising enjoyment.

For a healthy version, try substituting whole wheat pastry flour for some of the cake flour and swap half the butter for unsweetened applesauce. The cake will be just a bit denser, but still moist with a subtle fruity note.

To create a budget version, use all-purpose flour instead of cake flour and skip the extra egg yolks. Replace some of the butter with margarine or more vegetable oil. You’ll still get a tasty result with minor changes in softness and richness.

A kid-friendly version leaves out the rum entirely. Replace the rum in both the batter and syrup glaze with orange juice or apple juice. The cake becomes a citrusy, moist vanilla treat that kids will love with a glass of milk.

For a flavor twist version, swap dark rum with coconut rum or spiced rum and add a handful of shredded coconut to the batter. This adds tropical depth and a slightly chewy texture that balances the melt-in-your-mouth crumb.

How to Make Moist Rum Cake Recipe

Step 1

Start by preheating your oven to 325°F. Greasing and flouring your Bundt or tube pan is a small detail that makes a big difference. You want every curve of the pan coated to prevent sticking, especially since the syrup will later make the cake more delicate. Make sure to get into every crevice with butter and then dust with flour, tapping out the excess. If you have baking spray with flour, you can use that too.

Step 2

Now prepare your dry ingredients. Sift together the cake flour, baking powder, and salt in a medium bowl. Sifting is key here. It lightens the flour and evenly distributes the leavening agent and salt. This step also prevents lumps from forming in the batter and ensures a smooth, even texture. Set the bowl aside so it’s ready when you mix the wet ingredients.

Step 3

Creaming the butter and sugar is where the magic of fluffiness begins. Use an electric mixer on medium speed and beat the butter and sugar for about 3 to 5 minutes. The mixture should look pale and expand in volume. That’s the air you want in the batter. Add in the vegetable oil to enhance moistness. It will lighten the texture and extend shelf life. Then, add eggs and yolks one at a time, beating well. This step helps the batter stay emulsified. If it looks curdled, keep mixing slowly until smooth again. Add in the vanilla extract and dark rum now. The batter will be fragrant and creamy.

Step 4

Time to combine wet and dry. Starting with the flour mixture, alternate with the whole milk. Begin and end with flour, adding portions slowly on low speed. This five-step process creates a fine crumb and prevents batter separation. Watch closely at this stage. Over-mixing will toughen the cake. Once the flour disappears into the batter, stop mixing. The batter should be silky and slightly thick.

Step 5

Pour the batter into the prepared pan. Smooth the top with a spatula and make sure it’s evenly spread. This ensures even baking. Tap the pan gently on the counter to release any trapped air bubbles. Now, place it in the preheated oven and bake for 60 to 65 minutes. To test doneness, insert a toothpick into the center. If it comes out clean or with a few moist crumbs, it’s ready. Avoid overbaking, as this will dry out the cake despite the syrup.

Step 6

Prepare the rum syrup glaze while the cake is baking. In a small saucepan, combine the butter, sugar, water, and salt. Stir constantly over medium heat until the sugar dissolves completely. The mixture should simmer gently for 3 to 4 minutes and turn glossy. Once done, remove from heat and add the dark rum. Be cautious, as it might steam briefly. Let the syrup sit while the cake finishes baking.

Step 7

After baking, let the cake cool in the pan for 15 minutes. While still warm and in the pan, poke holes all over using a skewer, knife tip, or fork. This helps the syrup soak in deeply. Slowly spoon or pour the warm rum syrup over the cake. Take your time. Let it absorb. Too fast, and the syrup runs off. Allow the syrup to work its way into every air pocket and crumb.

Step 8

Let the cake cool completely in the pan before attempting to remove it. This patience rewards you with a clean release and moist result. Once cooled, carefully invert the cake onto a plate or stand. If you greased and floured the pan well, the cake should come out smoothly. Slice and serve when ready. The flavor intensifies as it rests, making it even better the next day.

Pro Tips for Making Moist Rum Cake Recipe

Use room temperature ingredients. Cold eggs or milk won’t mix well and can cause the batter to curdle. Room-temp ingredients create an even, well-emulsified batter that traps more air.

Avoid overmixing once you add flour. Overmixing will develop gluten, making the cake dense instead of soft and tender.

Measure flour carefully. Too much flour leads to a dry cake. Spoon it into your measuring cup and level off rather than scooping directly.

Let the syrup soak in fully. Don’t rush this step. Pour it slowly in batches if needed. Waiting between pours allows thorough absorption, keeping the cake moist for days.

Pay attention to oven temperature. Too hot, and the outer crust will overbrown while the center remains undercooked. Use an oven thermometer for accuracy.

Use a quality rum. A smooth, flavorful dark rum makes a noticeable difference. Avoid overly harsh or cheap brands, as those can overpower the cake.

Don’t remove the cake too soon. If the cake hasn’t cooled enough, it may break apart when you invert it. Patience here means presentation perfection.

Sift the flour. Don’t skip this old-school step. It breaks up any clumps and aerates the flour, which contributes to the light, delicate crumb.

Storing Leftovers

Store your leftover rum cake tightly wrapped in plastic wrap or inside an airtight container at room temperature for up to three days. If your kitchen is especially warm, it’s better to refrigerate it. The cake actually gets more flavorful a day or two after baking as the syrup penetrates every layer. Before serving leftovers, allow refrigerated slices to return to room temperature, which helps restore the cake’s soft texture and robust rum aroma. Avoid storing it uncovered, as the exposed surface can dry out and lose its signature moistness.

Freezing

Moist Rum Cake freezes beautifully if stored correctly. Wait until the cake is completely cool, then wrap it tightly in two layers of plastic wrap followed by a layer of aluminum foil to prevent freezer burn. You can freeze individual slices or the whole cake. Store it in the freezer for up to three months. When you’re ready to enjoy it, place it in the refrigerator overnight to thaw slowly. For the best texture, allow it to reach room temperature before serving. The syrup in the cake helps maintain its moist consistency, even after weeks in the freezer.

Reheating

To reheat a slice of rum cake, place it on a microwave-safe dish and cover it loosely with a damp paper towel. Warm it in the microwave for 10 to 15 seconds, just until slightly warm. You don’t want it to get too hot, or it could dry out quickly and lose that lovely softness. If you’re reheating several slices, you can wrap them in foil and place them in a 300°F oven for about 10 minutes. Never heat the entire cake at once. Warming individual pieces ensures better flavor and preserves the cake’s tender texture.

FAQs

Can I make this cake without alcohol?

Yes, you can make a non-alcoholic version by substituting the dark rum with apple juice or orange juice in both the cake and glaze. While it won’t have the same rich rum flavor, the result will still be sweet, moist, and delicious. The fruit juices add a bright note that makes the cake citrusy and refreshing.

Why is my rum cake dry?

Dry rum cake usually comes from overbaking or adding too much flour. Be sure to spoon and level your flour, use a kitchen thermometer to check baking temperature, and don’t bake it past doneness. Also, give the syrup time to fully soak in. If rushed, it won’t moisturize the interior properly.

What type of rum is best for rum cake?

Dark rum is the preferred choice. It has a molasses-like depth and rich flavor that complements the buttery sweetness of the cake. Brands like Myers’s or Gosling’s are popular options. For fun variations, try spiced rum or even coconut rum, depending on the flavor profile you prefer.

Can I make this cake a day ahead?

Yes, in fact, making the cake a day before serving is ideal. The syrup continues to soak in overnight, making the texture even more moist and flavorful. Store it tightly wrapped at room temperature or in the fridge, and let it come to room temp before serving.

What pan works best for this recipe?

A Bundt pan or tube pan is perfect for this moist rum cake. The central opening helps ensure even baking, and the decorative shape adds visual appeal. Just make sure to grease and flour the pan thoroughly so that the cake releases cleanly after baking.

How do I know when the cake is done?

Insert a toothpick into the thickest part of the cake. If it comes out clean or with just a few crumbs, it’s ready. The cake should also feel springy to the touch and pull slightly away from the sides of the pan. Don’t rely on time alone; ovens vary.

Can I reduce the rum in the recipe?

You can, but the result won’t be as flavorful. If you’re sensitive to alcohol, reduce the rum slightly and increase vanilla or replace with juice. Just make sure the total liquid remains the same to avoid changes in texture.
