Lemon Cupcakes

  • 1 cup white cake mix
  • 1 large egg
  • ½ cup water
  • 1 teaspoon lemon zest
  • 2 tablespoon lemon juice
  • ½ cup lemon curd

Lemon Buttercream

  • ½ cup unsalted butter, room temp
  • 3 cups powdered confectioners sugar
  • 2 tablespoon lemon juice
  • ½ teaspoon vanilla extract
  • 1 dash kosher salt
  • lemon zest for garnish


Lemon Cupcakes

  • Preheat the oven to 350°F and prepare a cupcake pan with liners.
  • Add all the cupcake ingredients except the lemon curd to a mixing bowl and mix on medium speed with a mixer for about 2-3 minutes.
  • Place batter into each cupcake liner about ¾ full and bake for 16-18 minutes.
  • Remove the cupcakes from the oven and allow them to cool in the pan for about 5 minutes and then transfer to a wire rack to cool completely before filling or frosting.

Lemon Buttercream

  • Place the butter into a mixer bowl and beat on medium speed for 2-3 minutes.
  • Add the powdered sugar one cup at a time and incorporate it completely after each addition.
  • Add the lemon juice, vanilla, and salt and beat until creamed together and smooth.

Fill and Frost the Cupcakes

  • After the cupcakes have cooled completely, place the lemon curd in a pastry bag with a round tip attachment (you can also use a ziplock bag). Gently Insert the tip into the top of the cupcake about ½" deep. Squeeze in some lemon curd (about a teaspoon). The cupcake will expand slightly, stop as the curd oozes out of the top a little. Don't worry what it looks like, you are covering it with frosting!
  • Place the frosting in a different pastry bag. Use your favorite tip and frost the cupcakes. Sprinkle with lemon zest and enjoy!


  • I zested and juiced 4 Meyer lemons for the cupcakes, buttercream, and lemon curd recipes at the start and set it all aside. It made each step with lemon juice or zest so much easier!
  • Of course, if you don't have Meyer lemons, regular lemons will work just as well.
  • This recipe is for 12 mini-cupcakes. If you want to make regular-sized cupcakes, you can double this recipe and add 6-7 minutes to the cooking time (check with a toothpick).
