Ingredients
  

For the Cupcakes
  • 1.5 cups all-purpose flour
  • 1 cup granulated sugar
  • 0.5 teaspoon baking powder
  • 0.25 teaspoon baking soda
  • 0.25 teaspoon salt
  • 0.5 cup unsalted butter, softened
  • 2 large eggs
  • 0.5 cup sour cream
  • 0.25 cup fresh key lime juice
  • 1 tablespoon key lime zest

For the Frosting

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C) and line a cupcake pan with paper liners.
  2. In a bowl, whisk together the flour, baking powder, baking soda, and salt.
  3. In a separate large bowl, beat the butter and sugar together until light and fluffy. Add the eggs one at a time, mixing well after each addition.
  4. Stir in the sour cream, key lime juice, lime zest, and vanilla extract until combined.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
  6. Divide the batter evenly among the cupcake liners and bake for 18-20 minutes, or until a toothpick comes out clean.
  7. Allow the cupcakes to cool completely.
Frosting
  1. For the frosting, beat the cream cheese until smooth, then gradually add the powdered sugar and 1/4 cup key lime juice. Mix until creamy and smooth.
  2. Frost the cooled cupcakes with the key lime cream cheese frosting and top with additional lime zest if desired.

Notes

Key Lime Cupcakes are best enjoyed fresh but can be reinforced with lime slices or mint leaves. Store in an airtight container for freshness. For extra lime flavor, add more zest.
