Ingredients

Scale

For the Shortbread Crust:

  • 1 cup (2 sticks) unsalted butter, softened
  • ½ cup granulated sugar
  • 2 cups all-purpose flour
  • ¼ teaspoon salt

For the Lemon Filling:

  • 4 large eggs
  • 1 ½ cups granulated sugar
  • ⅓ cup all-purpose flour
  • ½ cup fresh lemon juice (about 34 lemons)
  • 1 tablespoon lemon zest
  • ¼ teaspoon salt
  • 1 teaspoon vanilla extract
  • 2 tablespoons cornstarch

For the Meringue Topping:

  • 4 large egg whites, room temperature
  • ½ teaspoon cream of tartar
  • ½ cup granulated sugar
  • 1 teaspoon vanilla extract

Instructions

1. Prepare the Shortbread Crust:

  1. Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.
  2. In a mixing bowl, beat butter and sugar until light and fluffy.
  3. Add flour and salt, mixing until a crumbly dough forms.
  4. Press dough evenly into the bottom of the prepared pan.
  5. Bake for 18-20 minutes, or until lightly golden.
  6. Remove from the oven and set aside while you prepare the filling.

2. Make the Lemon Filling:

  1. In a bowl, whisk together eggs, sugar, flour, cornstarch, and salt until smooth.
  2. Stir in lemon juice, lemon zest, and vanilla extract until well combined.
  3. Pour the mixture over the warm crust.
  4. Bake for 20-25 minutes, or until the center is set and no longer jiggles.
  5. Let cool slightly while preparing the meringue.

3. Prepare the Meringue Topping:

  1. In a clean bowl, beat egg whites and cream of tartar until soft peaks form.
  2. Gradually add sugar, one tablespoon at a time, while continuing to beat until stiff, glossy peaks form.
  3. Mix in vanilla extract.
  4. Spread the meringue evenly over the warm lemon layer, ensuring it touches the edges of the pan.
  5. Bake for 10-12 minutes, or until the meringue is golden brown.

4. Cooling and Serving:

  1. Allow bars to cool completely at room temperature, then refrigerate for at least 1 hour before slicing.
  2. Cut into squares and serve chilled.

Notes

  • Use fresh lemons for the best citrus flavor—bottled juice won’t taste as vibrant.
  • Don’t skip the cornstarch in the filling; it helps it set properly.
  • Make sure the meringue touches the edges to prevent it from shrinking.
  • Chill before slicing for the cleanest cuts and best texture.
  • Store leftovers in an airtight container in the fridge for up to 3 days.
