Instructions

For the Cupcakes

  • Preheat the oven to 350 degrees, add paper cupcake liners to cupcake pan(s)
  • In a medium bowl, whisk the cake flour, baking powder, baking soda, and salt for 30 seconds. Set aside
  • In another bowl, add the buttermilk, vegetable oil and lime extract, lime juice & zest. Set aside.
  • In the bowl of your mixer, add the butter and mix at medium speed until smooth. Gradually add the sugar and continue to mix on medium speed for 3 to 5 minutes until lightened in color and fluffy.
  • Add the eggs one at a time, mixing after each until the yellow of the yolk has blended.
  • With the mixer on low speed, alternately add the flour mixture and buttermilk mixture, beginning and ending with the dry ingredients (3 additions of dry ingredients and 2 of liquid).
  • Mix just until incorporated. Be careful not to over-mix.
  • Scoop about ¼ cup bake batter into each cupcake liner (in the cupcake pans)
  • Bake at 350 degrees for 15-18 minutes or until a toothpick inserted in the center comes out clean or with just few crumbs attached. We like to remove cupcakes immediately from the pans to prevent over-baking. Baking times can vary depending on pan & oven- check at 15 minutes to be on the safe side, but it may take a few minutes more.
  • Makes 30-32 cupcakes (approximately ¼ cup of batter per cupcake)

For the Coconut Cream Cheese Frosting

  • Add the softened butter to the bowl of your mixer, mix until smooth.
  • Cut the softened cream cheese into pieces and add to the butter, mixing until blended.
  • Add the coconut extract.
  • Gradually add powdered sugar and mix until well blended.
  • This frosting will pipe best if used while still chilled. You can make it in advance, refrigerate and when ready to use let it soften slightly and remix. Do not microwave to soften. If the frosting becomes too soft while using just refrigerate the piping bag or bowl for a short while to firm it up.

Notes

Substitute for Buttermilk: No Buttermilk? Here is a substitution: To a measuring cup, add 1 Tablespoon plus one teaspoon vinegar or lemon juice. Add milk to the 1 ¼ c. mark, stir. Wait 5 minutes and it is ready to use.
Refrigeration & Serving: Because of the cream cheese frosting, these cupcakes need refrigeration. Remove two hours before serving to allow for the frosting and cupcakes to warm and soften.
 
Recipe makes approximately 7 ½ cups batter.
