Instructions
  1. For the cupcakes:
  2. Pre-heat oven to 350 degrees. Line a 12-cup cupcake pan with liners and set aside.
  3. In a large bowl, combine your dry ingredients and whisk to combine, then set aside.
  4. In a small saucepan, muddle the fresh mint leaves. if you don't have a muddler, use the back of a wooden spoon to smash the leaves and release their aroma. Add the milk and bring to just a simmer over medium heat. Remove from heat and allow to steep for about 15 minutes.
  5. In the bowl of a stand mixer fitted with a paddle attachment, cream the butter until smooth about 2 minutes. Slowly add in the sugar and continue to beat for another 3 to 5 minutes until light and fluffy.
  6. Add the mascarpone and beat until combined.
  7. Beat the egg whites until slightly foamy. Add to the butter sugar mixture in three pours. Beat after each addition until incorporated.
  8. Strain the milk through fine mesh strainer, add the rum, lime juice and vanilla extract and stir to combine.
  9. Add ⅓ of the dry ingredients and mix until just incorporated. Add half of the wet mixture and combine. It will curdle some, that’s ok. Add another third of the dry and mix. Then add the rest of the wet mixture and combine. Last, add the rest of the dry ingredients and mix to combine. Do not over mix.
  10. Add the lime zest and stir to incorporate.
  11. Using an ice-cream scoop or about ⅓ cup, fill each cupcake liner ⅔ rds full. Gently even out tops with offset spatula or knife.
  12. Bake on middle rack of the oven for 16 to 18 minutes until toothpick inserted comes out clean.
  13. Let cool for 10 minutes in pan on rack. Then remove from pan and allow to cool completely on the rack.
  14. For the buttercream:
  15. Add the butter to the bowl of a stand mixer fitted with the paddle attachment. Mix until the butter is smooth, about 2 minutes.
  16. Add the confectioners sugar one cup at a time at low speed. Increase speed after each addition to incorporate.
  17. Half-way through add the lime juice, rum and heavy cream.
  18. Add the rest of the sugar and mix until smooth. Add more cream one tablespoon at a time if a smoother consistency is desired.
  19. Place frosting fitted with a tip of your choice in a pipping bag and decorate cooled cupcakes.
  20. Garnish each cupcake with more lime zest and a fresh mint leave.
  21. Keep covered at room temp for a day or in the fridge for 3 to 5.
