Coconut Rum Cake: A Taste of Paradise

I can almost feel the warm Caribbean breeze just thinking about this Coconut Rum Cake. It reminds me of a small bakery I stumbled upon during a trip to Barbados years ago. The air hung thick with the scent of sugar and rum, and this cake, with its snowy white frosting and generous shower of toasted coconut, was the star of the show. One bite, and I was transported to a place of pure bliss. I knew I had to recreate this taste of paradise back in my own kitchen, and this recipe is the closest I’ve come to capturing that magical moment.

2 tablespoons heavy cream, plus more as needed

Instructions

Preheat your oven to 350°F (175°C), positioning a rack in the middle. Lightly butter your cake pan and then line the bottom with a round of parchment paper. Lightly butter the parchment, then flour the pan, ensuring even coverage. This helps prevent the cake from sticking.
In a medium bowl, whisk together the 1 1/4 cups of all-purpose flour, 1 1/2 teaspoons of baking powder, and 1/4 teaspoon of salt. This ensures the baking powder and salt are evenly distributed throughout the flour, leading to a more consistent rise and flavor.
In a large bowl, whisk together the 4 large eggs plus 3 large yolks, 1 1/2 cups of sugar, and 1 teaspoon of pure vanilla extract. The extra yolks add richness and tenderness to the cake.
Gradually whisk the flour mixture into the egg mixture until just combined. Be careful not to overmix, as this can develop the gluten in the flour and result in a tough cake. Then, whisk in the 3/4 cup of melted and cooled butter until just combined. The butter should be cooled to prevent it from cooking the eggs.
Pour the batter into the prepared cake pan and rap the pan on the counter to expel any air bubbles. This will help create a more even crumb.
Bake for approximately 45 minutes, or until the cake is golden brown and begins to pull away from the sides of the pan. A toothpick inserted into the center should come out clean. Keep a close watch, as baking times can vary depending on your oven.
Cool the cake in the pan on a rack for 10 minutes. Leaving it to cool slightly in the pan prevents it from breaking when inverted.
(Leave the oven on.) Invert the cake onto the rack, discarding the parchment paper. Cool for another 10 minutes.
While the cake is still warm, generously brush the top and sides with 3/4 cup of cream of coconut, allowing it to soak in before brushing on more. The warmth helps the cream of coconut penetrate the cake, making it incredibly moist and flavorful. Cool completely.
To prepare the coconut slivers, pierce the softest eye of the coconut with a small screwdriver, then drain and discard the liquid. While you don’t need the liquid for this recipe, you could save it to add to smoothies or tropical drinks.
Bake the coconut in a shallow baking pan for 15 minutes. This pre-baking step helps to loosen the coconut meat from the shell. (Leave the oven on.)
Break the shell with a hammer, then pry the flesh from the shell with a screwdriver. Be careful during this process, as the shell can be quite hard and sharp.
Thinly shave enough coconut with a slicer to measure 2 cups. Toss the shaved coconut with 2 teaspoons of confectioners’ sugar, then spread in a single layer on a baking sheet.
Bake the coconut until just dry but not golden (some tips may color), about 5 to 10 minutes. Watch it closely, as it can burn quickly. Cool the coconut completely. It will crisp up as it cools. Shave and bake any remaining coconut with more confectioners sugar to serve on the side, or freeze for another use.
To make the icing, beat together 3 tablespoons of softened cream cheese, 3 tablespoons of cream of coconut, 2 tablespoons of dark rum, 3/4 teaspoon of pure vanilla extract, and 2 tablespoons of heavy cream with an electric mixer until smooth.
Gradually beat in 1/2 cup of confectioners’ sugar. The icing should be smooth and slightly runny; stir in the remaining tablespoon of heavy cream if necessary to reach the desired consistency.
Smooth the icing over the top of the cooled cake, allowing some to drip over the sides, then top with the toasted coconut slivers.

Expert Tips & Tricks

For an even more intense coconut flavor, add a teaspoon of coconut extract to the cake batter.
If you don’t have fresh coconut, you can use sweetened shredded coconut for the topping. Just be sure to toast it lightly in a dry pan before using.
If you’re short on time, you can skip making the coconut slivers and simply use toasted coconut flakes.
To prevent the cake from sticking, make sure to thoroughly grease and flour the cake pan.
Don’t overbake the cake, as it can become dry. It’s better to err on the side of slightly underbaked.

Serving & Storage Suggestions

Leftovers can be stored in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. The cake can also be frozen for up to 2 months.

FAQs (Frequently Asked Questions)

Q: Can I use a different type of rum?
A: Yes, you can substitute a spiced rum or a light rum for the dark rum in the icing. The flavor will be slightly different, but still delicious.

Q: Can I make this cake ahead of time?
A: Absolutely! The cake can be baked one day ahead and soaked with cream of coconut, then kept in an airtight container at room temperature. The icing can also be made up to two hours ahead of time.

Q: How do I prevent the coconut from burning while toasting?
A: Keep a close eye on the coconut while it’s toasting and stir it frequently to ensure even browning. Reduce the oven temperature if it starts to brown too quickly.

Q: Can I use canned coconut milk instead of cream of coconut?
A: No, cream of coconut is a sweetened, thickened product, whereas coconut milk is thinner and less sweet. They are not interchangeable in this recipe.

Q: Can I freeze the cake?
A: Yes, the cake can be frozen. Wrap it tightly in plastic wrap and then in foil before freezing. Thaw it overnight in the refrigerator before serving. It’s best to freeze the cake before icing.
