  • ½ cup butter room temperature
  • 1 cup granulated sugar
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 1 ½ cups all-purpose flour
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • ½ cup milk
  • ¼ cup lemon juice
  • 1 Tablespoon lemon zest


  • 1 cup salted butter room temperature
  • 4 cups powdered sugar
  • 2 Tablespoons heavy whipping cream
  • 1 Tablespoon lemon zest
  • 1-2 Tablespoons lemon juice


  • Preheat oven to 350 degrees F. Line a muffin pan with cupcake liners.
  • In a large bowl, beat the butter and sugar until light and creamy, about 2 minutes. Add the eggs and vanilla and beat again, scraping down the sides of the bowl as needed.
  • Add flour, baking powder, and salt and mix until combined.
  • Add milk, lemon juice, and lemon zest, mixing again until combined.
  • Scoop the batter into prepared cupcake liners, filling them about ⅔ full. I find a medium cookie scoop works best. Bake the cupcakes for 15-18 minutes until the tops bounce back when you touch them or a toothpick inserted in the center of the cupcakes comes out clean. Cool completely.
  • Make the frosting by beating the butter in a large bowl until creamy and light, about 2-3 minutes.
  • Add half of the powdered sugar, mixing on a low speed until combined. Add remaining powdered sugar and mix again.
  • Add heavy cream, lemon juice, and lemon zest, mixing until light and creamy. Adjust powdered sugar or lemon juice to make the frosting thicker or thinner, as needed.
  • If using lemon curd as a filling, cut a small cone out of the top of each cupcake like hulling a strawberry. Fill with 1-2 tablespoons of lemon curd, then replace the plug.
  • Pipe lemon frosting on top of each cupcake using a decorative tip, then serve.
