Ingredients for appleton rum cake
Twelve ingredients, one decadent cake with rum-soaked layers and a crackly caramelized top.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 2 cups | White sugar preferred |
| Light Brown Sugar 🍚 | 1 cup | Packed for moisture |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, full-fat |
| Appleton Estate Rum (or similar dark rum) 🍹 | 1 cup | 18-year aged preferred |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Pure Vanilla Extract 🌿 | 2 tsp | High-quality preferred |
| Ground Cinnamon 🌶️ | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌶️ | 1 tsp | Freshly grated nutmeg |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Baking Powder 🍞 | 2 tsp | Aluminum-free preferred |
| Buttermilk 🥛 | 1 cup | Homemade or store-bought |
| Powdered Sugar 🍚 | 2 cups | For caramelized top |
| Heavy Cream 🥛 | ½ cup | Cold for glaze |
| Dark Brown Sugar 🍚 | ¼ cup | Packed for glaze |
The rum is the soul of this cake—Appleton Estate is ideal, but any 18-year dark rum works. Costco or BevMo usually carry it, but World Market has great selections too. If you can't find it, Havana Club 7 or Myers's are solid backups. The brown sugars are non-negotiable for moisture—pack them tightly in the measuring cup. For the butter, I always use Land O'Lakes unsalted because it melts beautifully, but Plugrá is worth the splurge if you're feeling fancy. The baking powder should be fresh—if it's over a year old, toss it.
No buttermilk? Mix 1 tbsp vinegar or lemon juice with 1 cup milk and let sit 5 minutes. Running short on rum? Substitute with 1/2 cup orange juice, but the flavor won't be identical. The vanilla extract should smell potent—if it's faint, double it. For the glaze, powdered sugar is essential—it creates that signature crackly top. If you're making this ahead, prep the rum syrup first and store it separately until baking day. The nutmeg should be freshly grated—pre-ground loses its punch quickly.
This cake tastes even better the next day as the flavors meld. Store wrapped tightly at room temperature for 3 days, or refrigerate for up to 1 week. For the glaze, make it fresh before serving—it sets quickly. I always bake two 9-inch rounds for parties because it disappears fast. The caramelized top? Don't overbake—it should be just set when you pull it from the oven. Let it cool completely before slicing, or you'll have crumbly edges.

Step-by-step instructions for Appleton rum cake
This cake delivers legendary moisture and a caramelized top that'll have everyone asking for seconds.
👨🍳 Step 1: Cream Butter and Sugars to Light and Airy
In a stand mixer fitted with the paddle attachment, beat the 1.5 cups unsalted butter (room temperature) with the 2 cups granulated sugar and 1 cup light brown sugar on medium speed for 3-4 minutes. You're looking for a pale, fluffy mixture that nearly doubles in volume—the butter should look almost translucent. This step incorporates air that creates that signature tender crumb.
Here's the thing—don't rush this. I've found that under-creaming leads to dense cake, while over-creaming can make it cakey. Stop when the mixture is light and fluffy, with ribbons forming when you lift the paddle. Scrape down the sides of the bowl to ensure even mixing before moving to the next step.
👨🍳 Step 2: Add Eggs and Rum for Maximum Moisture
Add the 4 whole large eggs (room temperature) one at a time, mixing on low speed for 30 seconds after each addition until fully incorporated. Then add the 1 cup Appleton Estate rum and 2 tsp pure vanilla extract, mixing just until combined. The rum adds incredible depth of flavor while keeping the cake moist for days.
I know it seems weird to add wet ingredients here, but trust me—the rum helps dissolve the sugars completely, creating a smoother batter. The mixture might look slightly curdled after adding the eggs, but don't worry. Once you add the dry ingredients, everything will come together beautifully.
👨🍳 Step 3: Combine Dry Ingredients and Buttermilk
In a separate bowl, whisk together the 3 cups all-purpose flour (sifted), 2 tsp ground cinnamon, 1 tsp ground nutmeg, 0.5 tsp salt, and 2 tsp baking powder. With the mixer on low speed, gradually add the dry ingredients to the wet mixture, alternating with the 1 cup buttermilk in 3 additions, beginning and ending with flour.
Mix just until combined—you should still see some flour streaks. Over-mixing develops gluten and makes the cake tough. The batter will be thick and slightly sticky, but that's exactly what we want for that perfect moist texture. Scrape the bowl one last time to ensure everything is evenly incorporated.
🥘 Step 4: Bake for Perfect Doneness
Preheat your oven to 350°F and grease two 9-inch round cake pans (or one 9x13-inch pan), then line the bottoms with parchment paper. Divide the batter evenly between the pans and smooth the tops. Bake for 25-30 minutes (for round pans) or 35-40 minutes (for the sheet pan) until a toothpick inserted in the center comes out clean.
Don't open the oven during baking—this prevents the cake from rising properly. The edges should be golden brown while the center remains slightly springy. For the caramelized top, immediately after removing from the oven, sprinkle the 2 cups powdered sugar evenly over the top of each cake while it's still hot. Let it sit for 5 minutes before inverting onto a wire rack to cool completely.
🍳 Step 5: Prepare the Rum Cream Glaze
While the cakes cool, prepare the glaze by combining the 0.5 cup heavy cream (cold) and 0.25 cup dark brown sugar (packed) in a small saucepan. Cook over low heat for 3-4 minutes, stirring constantly, until the sugar dissolves and the mixture thickens slightly. Remove from heat and let cool for 5 minutes.
Once the cakes are completely cool, spread the glaze evenly over the top of each cake. The glaze should be warm but not hot—this helps it adhere perfectly. Let the glaze set for 1 hour before slicing. The contrast between the moist cake and the caramelized glaze is what makes this rum cake legendary.
Pro Tips For Making Appleton Rum Cake
- Mix Dry Ingredients First: Sift the flour, baking powder, and salt together before cutting in the butter—this prevents lumps and ensures even distribution of leavening. I learned this the hard way when my first rum cake turned out dense; the baking powder was clumping, and the texture suffered.
- Use Cold Butter: Pull the unsalted butter straight from the fridge and cut it into cubes—no softening needed. Cold butter creates flakier layers and prevents the cake from becoming greasy, especially when paired with the moisture from the rum.
- Don’t Overmix the Batter: Mix the wet and dry ingredients just until combined—overworking the batter introduces too much air, which can cause a dense or tough cake. Stop when the flour is mostly incorporated; the rum will add enough moisture to finish the job.
- Soak the Rum Properly: Warm the Appleton rum slightly (just enough to release aromas) and mix it into the warm milk or buttermilk before adding to the batter. Cold rum can make the cake taste harsh, and skipping this step means losing that deep, caramelized flavor.
Storing and reheating your leftovers
Room Temp Storage
Keep your rum cake at room temperature in an airtight container for up to 3 days—the flavors actually deepen overnight. I wrap mine in plastic wrap first, then place it in a clear glass container with a tight lid.
The rum aroma intensifies as it sits, making every slice smell like a Caribbean vacation. Just be sure to store it away from direct sunlight to prevent the butter from turning rancid. 💛
Fridge Preservation
For longer storage, refrigerate the cake in an airtight container for up to 1 week. The cold helps preserve the moisture, but I recommend bringing it to room temperature before serving—cold cake can taste dense.
To prevent drying, I place a slice of bread on top of the cake before sealing the container. This little trick absorbs any excess moisture and keeps the cake tender. 🥖
Freezer Magic
This cake freezes beautifully for up to 3 months—perfect for making ahead for holidays. Wrap each layer tightly in plastic wrap, then place in a freezer bag with all the air squeezed out. For best results, freeze the cake before adding the glaze.
When ready to serve, thaw overnight in the fridge, then add the glaze fresh. The texture remains moist, though the glaze might need a quick reheat to set properly. ❄️
Glaze Refresh
The rum glaze hardens when chilled, so simply rewarm it gently in a microwave-safe bowl for 10-15 seconds to soften before spreading. For extra shine, brush a tiny bit of Appleton rum over the glaze after reheating—it adds an authentic rum cake aroma.
I also like to dust the top with powdered sugar right before serving for that classic presentation. The glaze should be warm but not runny when applied. 🍯
Serving Warm
Want to serve it warm? Reheat individual slices in a 350°F oven for 5-7 minutes until heated through. The glaze will soften beautifully, and the cake will smell like a bakery.
For a quick fix, microwave a slice on 50% power for 10-12 seconds, then cover with a damp paper towel to restore moisture. The rum flavors really shine when warmed gently. 🔥
Make-Ahead Glaze
Prep the glaze ahead of time and store it in the fridge for up to 5 days in an airtight jar. Reheat it gently on the stovetop over low heat for 2 minutes before spreading.
I always double the glaze recipe when making ahead—it's worth having extra for touch-ups or second servings. The glaze tastes even better after resting, as the flavors meld with the cake's spices. 💫

Frequently asked questions
Can I substitute regular rum for Appleton?
Yes, but there's a difference! Appleton Estate rum has a rich, spiced profile that works perfectly with this cake. For a substitute, use 18-year dark rum like Havana Club 7 or Myers's—avoid light rums or flavored varieties. If you can't find dark rum, 1/2 cup orange juice works in a pinch, though the flavor won't be identical. The alcohol content helps keep the cake moist, so don't skip it entirely.
Why does my rum cake turn out dry?
Dry cake usually means overbaking or not enough moisture sources. First, check your baking time—the cake is done when a toothpick comes out clean (25-30 minutes for round pans). Second, ensure you're using room-temperature butter and packed brown sugar—these add moisture. Finally, the rum-soaked syrup is critical: pour it over the warm cake immediately after baking. If you skip this step, the cake will dry out faster.
How do I make this cake gluten-free?
Replace the 3 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill or King Arthur). Add 1/2 tsp xanthan gum to help bind the cake. For the buttermilk substitute, use 1 cup dairy-free milk (like almond or oat) plus 1 tbsp vinegar. The texture will be slightly denser, but the rum flavor will still shine. Always weigh your gluten-free flour for accuracy—it's lighter than regular flour.
Can I bake this in a bundt pan?
A 10-12 cup bundt pan works beautifully for this recipe. Reduce the baking time to 35-40 minutes and check for doneness early—bundt cakes can overbake quickly. Grease the pan thoroughly and dust with powdered sugar before adding the batter to prevent sticking. The rum glaze will create stunning drips down the sides, making it perfect for special occasions. Just be patient when cooling—bundt cakes need 1 hour to set completely.
How much rum is actually in each slice?
With 1 cup rum in the batter and additional rum in the glaze, each of the 12 servings contains about 1.5 teaspoons of alcohol per slice. That's a subtle boozy note without being overpowering. The rum cooks off slightly during baking, leaving just enough warmth to enhance the caramel and spice flavors. For kids or non-drinkers, you can reduce the rum to 1/2 cup in the batter and omit it from the glaze.
