Instructions
 

Coconut Cupcakes

  • Preheat the oven to 350F. Line two cupcake tins with cupcake liners.
  • In a large skillet, add the coconut and place over low heat.
  • Toast the coconut, stirring occasionally so that the coconut doesn't burn. Toast the coconut until lightly golden. Set aside one cup of the coconut for decorating.
  • In the bowl of stand mixer fitted with the paddle attachment, on medium low speed, beat together the butter and sugar until light and fluffy, about 3 minutes
  • Meanwhile, in a large bowl, whisk together the flour, cake flour, baking powder and salt.
  • In a large measuring cup, whisk together the coconut milk, half and half, vanilla, and coconut extract.
  • Add the eggs, one at a time, to the butter/sugar mixture, scraping the bowl after each addition.
  • On low speed, add the dry ingredients to the butter mixture in 3 parts, alternating with the wet ingredients, scraping the bowl after each addition.
  • Add the toasted coconut, reserving 1 cup for decorating.
  • Give the batter a final stir with a spatula to make sure everything is well incorporated.
  • Fill the cupcake lines ⅔ full. Bake cupcakes for 18-20 minutes or until the tops look just set and a toothpick comes out with few moist crumbs.
  • Cool the cupcakes in the pan for 5 minutes. Transfer the cupcakes to a cooling rack to finish cooling.

Caramelized Pineapple Filling

  • In a medium saucepan, over medium low heat, combine the butter, brown sugar, and salt, stirring until the sugar has melted and the mixture is smooth.
  • Add the drained pineapple, stirring to fully incorporate the brown sugar mixture.
  • Reduce the heat to low and simmer the pineapple mixture, stirring occasionally until most of the liquid has evaporated.
  • Remove the pineapple filling from the heat. Stir in the rum. Let the filling cool completely before using.

Pineapple Caramel Rum

  • In a medium sized saucepan, combine the sugar and the pineapple juice. Stir just until combined. 
  • Place the saucepan over medium heat. Let the sugar mixture cook, without stirring, until the sugar mixture turns a mid amber color. Take the mixture off the heat to stop the cooking process.
  • Add the butter to the saucepan and whisk to combine. Be very careful as the mixture is incredibly hot and will bubble up and steam when the butter is added. 
  • Whisk in the heavy cream, followed by the rum and the salt. Whisk until smooth.
  • Let the caramel cool in the pan for 10 minutes before transferring to a storage container to cool completely.

Pineapple Caramel Ermine Frosting

  • In a medium saucepan over medium heat, whisk together the milk, sugar, flour and salt, and bring to a boil.
  • When the mixture starts to boil, continue to cook, whisking constantly for another 2-3 minutes. The mixture will thicken and resemble pudding. Whisk in the rum.
  • Strain the mixture into a shallow container to remove any clumps. Place plastic wrap over the surface of the mixture to prevent a film from forming.
  • Leave to cool to room temperature or pop in the freezer for 15-20 minutes. It should be room temperature to touch, not cold.
  • When the mixture is cool, whisk in half of the pineapple caramel.
  • In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on medium-high speed until light and fluffy.
  • Add the room temperature flour mixture to the butter, a few tablespoons at a time, allowing it to incorporate fully before adding more.
  • Once combined, whip the frosting on high for 3-5 minutes until smooth, light and fluffy.
  • Taste the frosting. Add remaining caramel to taste, a tablespoon at a time.

Assemble cupcakes

  • Using a sharp knife, cut a hole into the center of the cooled cupcakes to create a space for the pineapple filling.
  • Spoon the pineapple mixture inside each carved out cupcake. Fill the cupcake with the filling to the top, about a heaping teaspoon full.
  • Top the cupcakes with pineapple caramel ermine frosting. Roll the cupcakes into the reserved toasted coconut.
  • Top with pineapple and a maraschino cherry.
  • Store in an airtight container for up to 3 days.
