  • ½ tsp salt
  • ½ cup butter softened
  • 1 cup granulated sugar
  • 2 large eggs room temp
  • 1 tsp vanilla extract
  • 1 tsp lime zest
  • ⅓ cup freshly squeezed lime juice

  • 1 cup unsalted butter
  • 3 cups powdered sugar
  • 2 tbsp lime juice

Instructions
 

  • Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners.
  • In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
  • In a large bowl, cream butter and sugar until light and fluffy. Add eggs one at a time, mixing well. Stir in lime zest and vanilla extract.
  • Gradually add dry ingredients to wet ingredients, alternating with lime juice and milk. Mix until just combined.
  • Divide batter evenly among liners, filling ¾ full. Bake for 18-20 minutes or until a toothpick inserted in the center comes out clean. Cool completely on a wire rack.
