Instructions

Make Lemon Curd:

  • Combine lemon juice, granulated sugar, egg yolks, and butter in a saucepan over medium heat.
  • Cook, whisking constantly, until the mixture thickens. Remove from heat and let cool.

2. Make Lemon Poppy Seed Cupcakes:

  • Preheat the oven to 350°F (175°C). Line a muffin tin with paper liners.
  • In a mixing bowl, combine granulated sugar and lemon zest. Set aside.
  • In another bowl, whisk together eggs and milk.
  • In a separate bowl, whisk the dry ingredients: flour, poppy seeds, baking powder, baking soda, and kosher salt.
  • Add the butter, milk, eggs, and fresh lemon juice to the dry ingredients. Mix until just combined.
  • Divide the batter evenly among the cupcake liners.
  • Bake for 20-22 minutes, or until a toothpick inserted comes out clean. Let the cupcakes cool completely.

3. Make Lemon Swiss Meringue Buttercream:

  • Beat the powdered sugar and butter together in a stand mixer until smooth and fluffy.
  • In a separate bowl, beat the egg whites, granulated sugar, and cream of tartar until stiff peaks form.
  • Gradually add the egg white mixture into the butter mixture, beating until smooth and silky.

4. Assemble the Cupcakes:

  • Once the cupcakes have cooled, carefully cut a small hole in the center of each cupcake.
  • Fill each hole with lemon curd.
  • Frost the cupcakes with the lemon Swiss meringue buttercream.

Notes

  • Make sure the cupcakes are completely cool before filling with lemon curd and frosting.
  • Store cupcakes in an airtight container to keep them fresh for up to 3 days.
