Bahamian Coconut Cake Recipe: Tropical Rum-Infused Layers with Vanilla Bean Depth

This Bahamian coconut cake recipe brings the islands' sun-drenched flavors to your kitchen with its rum-infused layers and vanilla bean depth. 🌴 The secret lies in soaking shredded coconut in dark rum overnight, creating a fragrant, caramelized base that defines Bahamian desserts. This isn't just cake—it's a celebration of tropical warmth in every moist, tender bite. What sets this recipe apart is the three-layer structure, where each layer is infused with coconut milk and rum for that signature island taste. The cake itself is light yet dense, thanks to a precise balance of flour, sugar, and baking powder, while the filling between layers is where the magic happens—creamy coconut custard with a whisper of cinnamon. The icing? A simple glaze of powdered sugar and coconut milk that keeps the cake from drying out. By the time you serve this cake, your kitchen will smell like vacation, and your guests will be transported to a Bahamian beach with every forkful. The rum-soaked coconut adds a subtle boozy warmth, while the vanilla bean elevates it to something truly special—restaurant-quality at home. Perfect for birthdays, holidays, or just because you deserve a taste of paradise. The best part? This cake keeps well for up to a week, allowing the flavors to deepen over time. Serve it warm with a scoop of vanilla ice cream or let it cool slightly for cleaner slices. Here's how to bring the Bahamas to your table.

Ingredients for bahamian coconut cake

Gather these tropical staples for a cake that tastes like Bahamian sunshine and rum-soaked memories.

The rum matters here—Kirkland Signature or Gosling's Black Seal are my go-tos, but any dark rum works. Soak the shredded coconut in it overnight (the good stuff, not the pre-shredded kind)—this is where the magic happens. For the vanilla, Madagascar Bourbon bean paste adds depth beyond extract. The flour? King Arthur or Gold Medal for consistent results. If your baking powder's older than a year, toss it—it loses potency fast. The coconut milk? Full-fat canned (like Thai Kitchen) gives that rich, creamy texture. Skip the light version—trust me on the full-fat version.

No dark rum? Spiced rum or even coconut rum works in a pinch, but the flavor won't be quite the same. Short on vanilla bean paste? Double the extract and add a pinch of cinnamon to mimic the depth. The shredded coconut can be toasted lightly before soaking—just 2 minutes in a dry pan—to enhance the nutty flavor. For the glaze, powdered sugar needs to be sifted (no lumps!) and the coconut milk should be chilled to avoid melting the cake layers. The cinnamon in the filling? Ceylon cinnamon if you want to splurge, but regular works fine.

This cake keeps beautifully—5-7 days at room temperature, wrapped tightly in plastic. For longer storage, freeze the whole cake (unfrosted) for up to 3 months. The rum-soaked coconut filling actually improves overnight, so making it ahead is worth the extra minute. Serve warm with vanilla ice cream or let it cool for cleaner slices. I always make a double batch—half goes to guests, half stays for 'emergency dessert' days.

Step-by-step instructions for Bahamian coconut cake

Here's how to create layers of tropical flavor with rum-soaked coconut and vanilla richness.

In a medium bowl, combine the 3 cups shredded coconut with 1 cup dark rum and 1.5 cups coconut milk. Mix until the coconut is fully saturated and let it soak overnight in the refrigerator. This step infuses the coconut with deep rum flavor and creates a moist filling. The next day, drain any excess liquid but keep the coconut mixture in the bowl.

Here's the thing—soaking overnight makes all the difference. The rum and coconut milk meld together, creating that signature Bahamian coconut flavor. If you're short on time, you can soak it for at least 4 hours, but overnight gives the best results. This filling will be used between the cake layers and on top.

In a stand mixer fitted with the paddle attachment, beat the 1.5 cups unsalted butter (room temperature) and 2.5 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. You're looking for a pale, ribbon-like consistency that nearly doubles in volume. This creaming process incorporates air, which creates a tender crumb.

I press down on the butter mixture with a spatula occasionally to ensure everything's well combined. The butter should be completely smooth with no lumps. If it looks too thick, let it sit at room temperature for another 5-10 minutes before proceeding. This is the foundation of your cake, so take your time here.

Add the 6 whole large eggs, one at a time, mixing well after each addition. Then stir in the 2 tbsp vanilla extract and 1 tbsp vanilla bean paste. Mix on low speed for another 1 minute until fully combined. The mixture should be thick and smooth with no streaks of egg white.

This is where the magic happens—the vanilla bean paste adds that extra depth of flavor that sets this cake apart from regular vanilla extract. The eggs provide structure and moisture. Here's a pro tip: make sure your eggs are at room temperature. Cold eggs can cause the butter to seize up and create lumps in your batter.

In a separate bowl, whisk together the 3.5 cups all-purpose flour, 2 tsp baking powder, 0.5 tsp salt, and 1 tsp ground cinnamon. Gradually add this dry mixture to the butter mixture, mixing on low speed just until combined. Be careful not to overmix—you should still see some flour streaks. Then fold in half of the soaked coconut mixture.

Overmixing develops gluten, which can make your cake tough. We want a tender, moist crumb. The coconut mixture should be evenly distributed but not overworked. The batter will be thick and slightly sticky—this is normal. Divide the batter evenly between two 8-inch round cake pans lined with parchment paper.

Preheat your oven to 350°F. Bake the cake layers for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Rotate the pans halfway through baking for even browning. Let the layers cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.

Don't skip the cooling step—this ensures clean layers when you assemble the cake. While the layers are cooling, prepare your coconut filling by mixing in the 2 cups powdered sugar and 1 tsp ground cinnamon to the soaked coconut mixture. This creates a sweet, spiced glaze that ties everything together.

Once completely cool, level the tops of the cake layers if needed. Place the first layer on a cake stand or plate, then spread half of the coconut filling evenly over the top. Add the second layer and spread the remaining filling on top. Finally, spread a thin layer of the remaining coconut mixture over the entire cake for decoration.

For the final touch, dust the top with additional powdered sugar and garnish with extra shredded coconut if desired. This cake is best served at room temperature, allowing all the flavors to meld together. The rum-soaked coconut filling will keep the cake moist for days, making it perfect for celebrations or special occasions.

Make-ahead tips for this bahamian coconut cake

Overnight Prep Advantage

The rum-soaking step is non-negotiable for authentic flavor, so start this process 24 hours ahead. I place the 3 cups shredded coconut in a quart-sized glass container with 1 cup dark rum and 1.5 cups coconut milk, sealing it tightly. The rum infuses the coconut overnight, creating a fragrant, caramelized base that's the heart of this cake. Store it in your fridge until ready to use—this prep step actually makes the cake easier to assemble later. 🌴

Batter Make-Ahead

Prepare the cake batter up to 24 hours before baking and store it in an airtight container in the fridge. The batter will thicken slightly, but just give it a good stir before dividing into pans. I like to label containers with the date to track freshness. This head start means you can bake the cake layers the next day without last-minute stress. The batter keeps well for 2 days refrigerated. ⏰

Layer Assembly Tips

Assemble the cake layers 4-6 hours before serving to allow flavors to meld. Place the first layer on a cake stand, then spread half the coconut filling evenly using an offset spatula. Add the second layer and top with remaining filling. Wrap the assembled cake in plastic wrap and refrigerate until ready to serve. This chilling time prevents the filling from melting into the layers too quickly. 💡

Filling Enhancement

For extra richness, mix 1 tbsp butter into the coconut filling before assembling. This creates a luscious, spreadable texture that stays moist longer. I also like to add a pinch of ground nutmeg to the filling for that classic Bahamian spice blend. The filling can be prepared 3 days ahead and stored in an airtight container in the fridge—it actually tastes better after resting. ✨

Storage Secrets

This cake keeps beautifully at room temperature for 5-7 days when wrapped tightly in plastic. For longer storage, freeze the fully assembled (unfrosted) cake for up to 3 months. To serve from frozen, thaw overnight in the fridge and bring to room temperature before slicing. The rum-soaked filling prevents drying, making this cake perfect for make-ahead celebrations. 💫
