Ingredients

  • 3 cups all-purpose flour
  • 1 tablespoon baking powder
  • 1/2 teaspoon salt
  • 1 cup (2 sticks) unsalted butter, room temperature
  • 2 cups sugar
  • 4 large eggs, room temperature
  • Finely grated zest of 3 lemons (about 3 tablespoons), plus 2 tablespoons fresh lemon juice
  • 1 teaspoon pure vanilla extract
  • 1 cup buttermilk
  • Lemon Curd (page 317)
  • Seven-Minute Frosting (page 303)

Method

  • Preheat oven to 325F.
  • Line standard muffin tins with paper liners.
  • Whisk together flour, baking powder, and salt.
  • With an electric mixer on medium-high speed, cream butter and sugar until pale and fluffy.
  • Add eggs, one at a time, beating until each is incorporated, scraping down sides of bowl as needed.
  • Beat in zest and vanilla.
  • Add flour mixture in three batches, alternating with two additions of buttermilk and lemon juice, and beating until just combined after each.
  • Divide batter evenly among lined cups, filling each three-quarters full.
  • Bake, rotating tins halfway through, until golden brown and a cake tester inserted in centers comes out clean, about 25 minutes.
  • Transfer tins to wire racks to cool completely before removing cupcakes.
  • Cupcakes can be stored overnight at room temperature, or frozen up to 2 months, in airtight containers.
  • To finish, spread 1 tablespoon lemon curd onto middle of each cupcake.
  • Fill a pastry bag fitted with a large open-star tip (Ateco #828 or Wilton #8B) with frosting.
  • Pipe frosting onto each cupcake, swirling tip slightly and releasing as you pull up to form a peak.
  • Hold a small kitchen torch (see Sources, page 342) 3 to 4 inches from surface of frosting, and wave it back and forth until frosting is lightly browned all over.
  • Serve immediately.
