Ingredients

  • 1 3/4 cups all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 2 large eggs
  • 1 3/4 cups granulated sugar
  • 1 cup whole milk
  • 3/4 cup vegetable oil
  • Finely grated zest of 2 lemons
  • 2 tablespoons fresh lemon juice
  • 1 teaspoon vanilla extract
  • 2 large egg whites
  • 1/4 teaspoon salt
  • 1/2 cup granulated sugar
  • 1/2 cup light corn syrup
  • 1/4 teaspoon vanilla extract
  • 2 1/2 cups confectioners' sugar
  • 1/4 cup fresh lemon juice (from about 2 lemons)
  • 1 tablespoon limoncello or other lemon-flavored liqueur (optional)
  • 6 to 7 drops yellow food coloring (optional)

Method

  • Make the cupcakes: Preheat the oven to 350 degrees F and line a 12-cup muffin pan with paper liners.
  • Whisk the flour, baking powder, baking soda and salt in a bowl until combined.
  • Whisk the eggs, granulated sugar, milk, vegetable oil, lemon zest, lemon juice and vanilla in a large bowl until combined.
  • Whisk the flour mixture into the egg mixture.
  • Divide the batter evenly among the prepared muffin cups, filling them to just below the rim.
  • Bake until a toothpick inserted into the center of a cupcake comes out clean, 25 to 30 minutes.
  • Let cool 15 minutes in the pan, then transfer to a rack to cool completely.
  • Make the meringue: Beat the egg whites and salt in a large bowl with a mixer on medium speed until foamy, about 1 minute.
  • Increase the mixer speed to high and gradually beat in 2 tablespoons granulated sugar; beat until stiff shiny peaks form, about 3 minutes.
  • Combine the remaining 6 tablespoons granulated sugar, the corn syrup and 1/4 cup water in a saucepan over medium-high heat.
  • Cook until the mixture registers 245 degrees F on a candy thermometer, about 6 minutes; remove from the heat.
  • With the mixer on medium speed, slowly pour the hot sugar syrup into the egg whites; increase the speed to high and beat until the meringue is fluffy and cool, about 6 minutes.
  • Beat in the vanilla.
  • Transfer the meringue to a pastry bag fitted with a large round tip and pipe onto the cupcakes; set aside at room temperature to firm up, about 15 minutes.
  • Meanwhile, make the glaze: Whisk the confectioners' sugar, lemon juice, limoncello and food coloring in a microwave-safe bowl until smooth.
  • Microwave 1 minute, then whisk again until the sugar dissolves; let cool about 5 minutes, stirring occasionally.
  • Dip the meringue-covered tops of the cupcakes into the glaze, letting the excess drip off.
  • If the glaze gets too thick, microwave 20 seconds.
