The rum is non-negotiable here—Appleton Estate delivers that authentic spiced depth, but any aged rum works in a pinch. Soak the dried fruit overnight in the rum plus 2 extra tablespoons to maximize flavor infusion. For the fruit, Trader Joe's or bulk bins have the best variety, but avoid anything with added sugar or sulfites. The butter should be room temperature but not melted; if it's too soft, chill it 20 minutes. European-style butter like Plugrá has higher fat content for richer flavor.
No Appleton rum? Havana Club or Gosling's Black Seal are solid substitutes, though the flavor profile will differ slightly. For the streusel topping, quick oats work too if you're in a hurry, but rolled oats give that perfect crumbly texture. The caramel swirl can be made from scratch (simmer sugar and cream until golden), or use high-quality store-bought caramel sauce like Smucker's for convenience. If your powdered sugar clumps, sift it through a fine-mesh sieve before whipping the buttercream. The baking powder matters—Diamond Crystal is double-acting, so if you use another brand, reduce to 1.5 teaspoons.
Store the cake layers separately in airtight containers between parchment paper for up to 3 days before assembly. The streusel topping can be prepped ahead and kept in the fridge for 5 days, or frozen for 3 months. Once assembled, the cake keeps for 4 days at room temperature in a cool, dark place. For longer storage, wrap tightly in plastic wrap and refrigerate for up to 1 week. The rum-soaked fruit flavor intensifies after baking, so don't rush the soaking—overnight is ideal. Leftovers? Slice and freeze for up to 2 months—perfect for quick dessert nights.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe because it’s one of those rare cakes where you don’t even need to cream butter and sugar by hand—just melt the butter, mix it with the sugars, and let the eggs pull it all together. The brown sugar’s caramel notes do half the work for you.
- Spiced Rum Magic: That first bite? Warm, buttery, and just a whisper of spiced rum lingering on your tongue. The brown sugar adds depth, but it’s the rum’s vanilla-cinnamon kiss that makes this cake feel like a hug from a favorite aunt—especially with a dusting of powdered sugar.
- Weeknight to Holiday: Honestly, I make this for everything: a lazy Sunday morning, a last-minute potluck, or when I’m too tired to bake but still want something impressive. The rich flavor holds up no matter the occasion, and the simple frosting (if you add it) lets you dress it up or keep it casual.
- Budget-Friendly Luxury: Here’s what sold me—the ingredients are basic but transformed by technique. Butter and eggs make it rich without breaking the bank, and the rum (even a small splash) elevates it to feel special. Leftovers? They’re even better the next day, sliced with a warm mug of coffee.
Step-by-step instructions for Appleton rum cake
Here's how to create a rich rum-infused cake with caramel swirls and a buttery oat streusel topping.
Prepare the Fruit and Soak the Cake Batter
Combine the 1.5 cups dried mixed fruit with 2 tablespoons Appleton Estate Rum in a bowl and let soak overnight. This step ensures the fruit absorbs moisture and flavor. In a separate large bowl, whisk together the 3 cups all-purpose flour, 2 cups granulated sugar, 1 cup light brown sugar, 2 teaspoons baking powder, and 0.5 teaspoon salt. Set aside.
In another bowl, beat the 1.5 cups unsalted butter until smooth and creamy, about 3-4 minutes. Add the 4 whole large eggs, one at a time, mixing well after each addition. Stir in the 1.5 cups Appleton Estate Rum and 2 teaspoons vanilla extract until fully combined. Gradually add the dry ingredients to the wet, mixing just until combined—overmixing develops gluten and makes the cake dense.
Create the Caramel Swirl and Assemble the Cake
Preheat your oven to 350°F and grease a 9x13-inch baking dish. Spread half of the batter evenly into the prepared dish. In a small saucepan, combine 1 cup granulated sugar and 2 tablespoons water, heating over medium heat until the sugar melts and turns into a light amber caramel. Immediately pour the caramel over the batter in the dish, then top with the remaining batter.
Using a knife, gently swirl the batter and caramel together in a circular motion to create ribbons. This step is crucial for the signature caramel swirls. Sprinkle the soaked fruit evenly over the top of the batter. The fruit will sink slightly as it bakes, releasing its flavors into the cake.
Prepare the Streusel Topping and Bake
In a medium bowl, mix together the 1 cup old-fashioned rolled oats, 0.5 cup shredded coconut, 1 teaspoon ground cinnamon, and 1 cup light brown sugar. Cut in the 1.5 cups unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Sprinkle this streusel evenly over the top of the cake.
Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown, and the streusel should be crisp. Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before frosting.
Make the Buttercream Frosting
In a medium bowl, beat the 1 cup heavy whipping cream until soft peaks form. Gradually add the 1 cup powdered sugar, beating until smooth and fluffy. Spread this buttercream evenly over the cooled cake. The frosting should be thick enough to hold its shape but still spreadable. Chill the cake for 30 minutes before slicing to allow the frosting to set.
Serve slices warm or at room temperature. The rum-infused cake layers will be moist, the caramel swirls rich and gooey, and the streusel topping will add a delightful crunch with every bite. Store any leftovers in an airtight container in the refrigerator for up to 5 days.
Pro Tips For Making Appleton Rum Cake
- Cream Butter Properly: I learned this the hard way—beat the butter and sugars until the mixture is pale and fluffy, not just "combined." For this cake, that means about 3-4 minutes with a stand mixer (or until you can press the dough and it holds a peak). The rum flavor needs room to shine, and a dense batter will make the cake taste flat.
- Use Cold Eggs: Pull the eggs straight from the fridge, crack them into a separate bowl, and let them sit for 5 minutes before adding to the batter. Cold eggs incorporate more smoothly and prevent the butter from melting too fast—critical when you’re mixing in rum and brown sugar, which can make the batter runny.
- Don’t Overmix the Rum: After folding in the Appleton rum, stop mixing as soon as the flour is just incorporated. Overworking the batter develops gluten, which turns this rich cake into a dense brick. Two quick swirls with a spatula are all it takes—your future self will thank you when the texture stays tender.
- Bake Until Springy: This cake’s magic comes from its moisture, so resist the urge to pull it out early. Press the center lightly—it should spring back slowly, not bounce right away. If the edges are set but the middle’s still jiggly, give it 5 more minutes. Underbaking is the fastest way to a gummy, sad cake.
Flavor customization for this recipe
Rum Intensity
Adjust the rum flavor to your taste by modifying the soaking time or quantity. For a subtle rum essence, soak the fruit for just 4-6 hours instead of overnight, then use 1 cup of rum in the batter.
For bold Caribbean flavors, increase to 2 cups of rum and add 1 teaspoon of rum extract to the batter. I often make a half-batch with 1 cup rum for weeknight baking—it’s still rich but not overpowering. 🍹
Spiced Variations
Enhance the rum cake’s complexity with warm spices. Add 1 teaspoon ground nutmeg or ½ teaspoon cardamom to the dry ingredients for a Middle Eastern twist. For a Mexican-inspired version, swap ½ cup of the dried fruit for chopped dried apricots and add ½ teaspoon cinnamon to the streusel.
The spices meld beautifully with the rum during baking. 🌶️
Caramel Depth
Customize the caramel swirl’s sweetness and texture. For a lighter caramel, reduce the sugar to ½ cup and add 1 tablespoon cream to the saucepan. For a deeper, salted caramel, increase the sugar to 1.5 cups and finish with a pinch of flaky sea salt after baking.
I love drizzling store-bought salted caramel sauce (like Smucker’s) over the buttercream for extra indulgence. 🍯
Fruit Swaps
Experiment with different dried fruits to change the texture and flavor profile. Replace the mixed fruit with ½ cup dried cherries and ½ cup chopped dates for a tart-sweet balance. For a tropical vibe, use ½ cup dried pineapple and ½ cup chopped apricots.
Soak all fruit in rum for the same overnight time to ensure even flavor infusion. 🍍
Topping Alternatives
Swap out the streusel for other textures. Try a chocolate ganache drizzle (melt ½ cup dark chocolate with ¼ cup heavy cream) for a decadent finish. For a nutty crunch, top with ½ cup chopped pecans or toasted coconut flakes.
I also love a lemon curd glaze—mix ½ cup powdered sugar with 2 tablespoons lemon curd and brush over the cake before adding buttercream. 🥥
Dietary Tweaks
Make this cake more inclusive without sacrificing flavor. For a gluten-free version, replace the flour with a 1:1 gluten-free baking blend (like King Arthur’s) and reduce the baking powder to 1.5 teaspoons.
For less sugar, reduce the granulated sugar to 1.5 cups and use ½ cup honey in the caramel swirl. The rum’s natural sweetness helps balance these changes. 💪

Frequently asked questions
Can I make this rum cake without alcohol?
Yes! Replace the rum with 1.5 cups apple juice or 1 cup orange juice + ½ cup water for moisture and depth. For extra flavor, add 1 teaspoon vanilla extract + ½ teaspoon almond extract to mimic rum's aromatic notes. The cake will still be moist but with a fruit-forward taste instead of boozy warmth.
How do I prevent the cake from sinking in the middle?
Underbaking slightly helps—pull the cake when a toothpick comes out with a few moist crumbs (40 minutes may suffice). Chill the baked cake 10 minutes before removing from the pan. For extra insurance, preheat your oven to 350°F and place the baking dish inside for 10 minutes before adding batter to equalize temperatures.
Can I bake this cake in a different pan size?
For a 9-inch round cake, divide the batter into three 9-inch layers (bake 25-30 minutes each at 325°F). For an 8x8-inch pan, reduce baking time to 35-40 minutes at 350°F. Always check doneness with a toothpick. The caramel swirls may need more time—keep an eye on the edges while the center sets.
Why does my cake taste dry after baking?
Overbaking or insufficient rum soaking are common culprits. Ensure the fruit soaks overnight—this adds moisture. For dry cake, brush warm layers with 2 tablespoons rum or simple syrup (equal parts sugar + water, heated) before assembling. The buttercream should also be thick but spreadable—if too stiff, add 1 teaspoon heavy cream to soften.
How do I store leftovers without drying out the cake?
Wrap each slice tightly in plastic wrap, then place in an airtight container with a slice of bread or cake board between layers to absorb moisture. Store at room temperature for 2 days or refrigerate for up to 5 days. For longer storage, freeze slices (unfrosted) for 2 months**—thaw at room temperature before serving.
