Ingredients

Scale

For the Crust

  • 1 cup unsalted butter, softened
  • 1 cup granulated sugar
  • 2 cups all-purpose flour
  • 1/4 teaspoon salt

For the Lemon Filling

  • 4 large eggs
  • 1 cup freshly squeezed lemon juice
  • 1 tablespoon lemon zest
  • 1 cup granulated sugar (assumed from instruction to whisk eggs, sugar, lemon juice, and zest; original recipe omitted explicit quantity so standard approximate used)

For Garnish

  • 1/2 cup powdered sugar, for dusting

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper for easy removal of lemon bars.
  2. Cream Butter and Sugar: In a mixing bowl, cream together the softened unsalted butter and granulated sugar until the mixture is light and fluffy, ensuring a smooth crust base.
  3. Form Crust Dough: Add the all-purpose flour and salt to the creamed mixture. Mix until a crumbly dough forms, making sure ingredients are well combined but do not overwork.
  4. Press Crust into Pan: Evenly press the crumbly dough into the prepared pan, creating a flat, uniform crust layer.
  5. Bake Crust: Bake the crust in the preheated oven for 20 minutes or until it turns lightly golden, indicating it is set and partially cooked.
  6. Prepare Lemon Filling: While the crust bakes, whisk together the eggs, granulated sugar, freshly squeezed lemon juice, and lemon zest until the mixture is smooth and well combined.
  7. Pour Filling Over Crust: Once the crust is warm from baking, carefully pour the lemon filling evenly over it to create the top layer of the bars.
  8. Bake Bars: Return the pan to the oven and bake for 25 to 30 minutes, or until the lemon filling is set but still slightly jiggles when shaken.
  9. Cool Completely: Remove the bars from the oven and allow them to cool completely in the pan at room temperature to ensure the filling sets fully.
  10. Dust with Powdered Sugar: Once cooled, generously dust the top of the lemon bars with powdered sugar before slicing into squares and serving.

Notes

  • Ensure the butter is softened but not melted for the best crust texture.
  • Freshly squeezed lemon juice gives the best bright, authentic flavor.
  • Cooling the bars completely helps the filling firm up properly to ease slicing.
  • Use parchment paper to lift the bars easily out of the pan.
  • Store leftovers in an airtight container in the refrigerator for up to 4 days.
