Ingredients

Cupcakes:

  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter melted
  • 1 1/4 cups sugar
  • 3 large eggs
  • 1 tablespoon vanilla extract
  • 1/4 cup fresh lemon juice from about 1/2 a large lemon
  • 1 tablespoon lemon zest from about 1 large lemon
  • 1/2 cup whole milk

Filling & Frosting:

  • 1/2 cup lemon curd jarred or from scratch for the filling
  • 1 cup unsalted butter softened
  • 4 1/2 cups powdered sugar
  • 1 tablespoon lemon zest 1 large lemon
  • 4 tablespoons lemon juice 1 large lemon
  • 1/4 teaspoon salt
  • 1-2 tablespoons heavy whipping cream for desired consistency

Instructions

  • Preheat oven to 350°F. Line cupcake tins with liners (makes 15-16 cupcakes).
  • Whisk flour, baking powder, and salt in a medium bowl.
  • Add melted butter to a large bowl and mix in sugar with a hand mixer for 30 seconds, until thick and yellow. Add eggs one at at time, beating after each addition. Beat in vanilla extract, lemon juice, and zest.
  • Add the flour mixture and milk alternately, starting and ending with the flour. Don’t over mix! Divide batter among liners, filling 2/3 full (about 1/4 cup of batter per cupcake). Bake for 13-18 minutes until a toothpick comes out clean. (Mine took about 14 minutes.) Cool completely before frosting.
  • To fill: cut out a small bit of the top/center of the cupcake. (Cut a hole that’s about the size of a dime and the amount of cupcake you take out is a little larger than a marble.) Fill each hole with about 1/2 - 1 tablespoon of lemon curd. Replace a piece of the cupcake to cover.
  • To make the frosting: Beat butter until creamy. Beat in salt and 1 cup of powdered sugar at a time until it’s all added.
  • Beat in lemon juice and zest. Add 1 tablespoon of heavy whipping cream and mix until smooth. Add more cream as needed for desired consistency. Frosting can be made up to 2 days ahead and stored in the refrigerator. Make sure to let it come to room temperature before using.
  • Frost cupcakes by placing frosting in a pastry bag. I like the 1M tip, it gives pretty swirls. Add extra lemon zest or sprinkles for decoration, if desired.
