Piña Colada Cake

Cakes, Desserts, Summer

I’ve made this cake exactly 10 times. Haha. Whenever I think I know what I’m doing, cakes love to come out of the oven all messed up and tasting mediocre; they laugh in my face and humble me right to the ground.

All that testing was worth it because we now have a delicious cake that will remind you exactly of a piña colada. It has a balance of flavors of equal parts pineapple, coconut and rum. It’s only slightly boozy-tasting.

When I was making this cake, it reminded me of Hawaii. And yeah, a lot of that has to do with how many frozen piña coladas I consumed before noon when I visited.

I’ve only been once—last year for the first time—and it truly is one of the most beautiful places I’ve been to. There’s a vibe in Hawaii, I can’t explain it. But I think whenever I go to lands where the indigenous culture is so alive and celebrated, it gives the place a magical vibe. I feel similarly when I visit New Mexico.

I love a sheet cake, always. I love their ease. Of course, I tried to make it all Hawaii-like with hibiscus flowers and tropical vibes. This is so unneeded.

The frosting is almost as good as the cake. I added some fresh pineapple into the frosting, along with some vanilla paste, coconut extract (very optional) and rum. It was SO good.

Piña colada cake tastes like the perfect combination of rum, coconut and pineapple. It's like your frozen drink in cake version. Topped with a boozy frosting that is so delicious.

Ingredients

Piña Colada Cake:

  • 2 1/2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1 teaspoon kosher salt
  • 1/2 cup unsalted butter, at room temperature
  • 1 cup white granulated sugar
  • 1 cup dark brown sugar
  • 2 tablespoons dark rum
  • 1/2 cup vegetable oil
  • 3 large eggs
  • 1/2 cup buttermilk, shaken
  • 1/2 cup shredded sweetened coconut

Rum Pineapple Frosting:

  • 1 cup unsalted butter, at room temperature
  • 3 cups powdered sugar
  • 1 tablespoon heavy cream or milk
  • 1 tablespoon dark rum
  • 1 teaspoon vanilla extract or vanilla paste
  • Pinch kosher salt
  • 1 slice canned or fresh pineapple, cut into a rough dice

Directions

To Make the Cake:

  • Preheat oven to 350 degrees F. Grease a 9x13-inch baking pan. I also like to line my baking pan with a parchment just to make sure nothing sticks. 
  • In a medium bowl, whisk together the flour, baking powder and salt. Set the dry mixture aside.
  • In the bowl of a stand-up mixer, with the paddle attachment, add the butter, white sugar, brown sugar and rum; beat until nice and fluffy, about 2 to 3 minutes. Pour in the oil and eggs. Beat until combined. 
  • Alternating between the buttermilk and the dry mix, add them to the butter mixture, until just combined. Lastly, add the shredded coconut and mix until distributed throughout the batter. 
  • Pour the batter into the prepared cake pan and spread the batter out until it reaches the edges. Transfer to the oven to bake for 35 to 40 minutes, or until a skewer inserted into the center comes out clean. 
  • Allow to cool in the pan for about 5 to 10 minutes and then transfer to a cooling rack to cool before adding the frosting. 

To Make the Frosting:

  • To a stand-up mixer (or alternatively you can do this in a large bowl with an electric mixer), add the butter. Beat the butter until smooth. And then add in the sifted powdered sugar, heavy cream or milk, rum and pinch of salt. Beat for about 2 minutes until the frosting is nice and fluffy. I find that heavy cream and beating the frosting is what really makes the frosting THAT much better. Lastly, add the diced pineapple and give it a mix one last time. 

To Assemble the Cake:

  • Pour all of the frosting on the cooled sheet cake and spread it around, creating cute swoops as you go. Top it with whatever you like! I piped out buttercream hibiscus flowers, see below for notes! Cake will stay moist for about 2 days when wrapped properly. 

Notes

To pipe out hibiscus flowers, used this tutorial. But instead of using bean paste, I obviously just used a regular buttercream.
I like using Americolor gel colors OR Wilton gel colors.
I use these piping bags and Wilton #104 tip (for the flowers) and Wilton #352 for the green leaves.

    Hi. How much rum do you add to the cake batter? It’s only listed as being added to the frosting but your instructions state to add rum to the cake batter.
    Thanks!

    IS there supposed to be rum in the cake batter? The instructions include it, but the ingredient list does not. Thanks!

    Do you use an offset spatula to transfer the flowers to the cake from the parchment paper? The one time I tried to make flowers on parchment and transfer them, they fell apart and I’m not sure if I have to wait for them to dry out a bit or maybe I’m just using the wrong tool.

      yes! but you have to transfer the flowers to the freezer first so they firm up. And then you transfer them. Some people transfer them when they’re warm but that has never worked for me.
