Ingredients Method Notes

Ingredients
  

For the crust
  • 2 cups all-purpose flour
  • ½ cup granulated white sugar
  • 1 cup salted butter (or unsalted plus ½ teaspoon coarse salt) Use unsalted if preferred
For the filling
  • 4 large eggs
  • 1 ½ cups granulated white sugar
  • ¼ cup lemon juice (freshly squeezed, from 2 or 3 lemons) Freshly squeezed is best
  • 1 ½ tablespoons lemon zest (zest of 2 lemons)
  • 3 tablespoons all-purpose flour Helps prevent clumps

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C). Line a 9×13-inch glass baking pan with parchment paper.
  2. In a large mixing bowl, combine 1 cup of softened butter and ½ cup of granulated white sugar. Mix until creamy.
  3. Gradually add 2 cups of all-purpose flour, blending until a thick dough forms.
  4. Spread the dough evenly into the prepared pan and bake for 15 to 20 minutes until lightly browned.
Filling
  1. While the crust is baking, whisk 4 large eggs in a separate bowl until smooth.
  2. Add in 1 ½ cups of granulated white sugar, ¼ cup of lemon juice, and 1 ½ tablespoons of lemon zest. Mix until well blended.
  3. Stir in 3 tablespoons of flour to prevent clumps.
  4. Once the crust has baked, poke it with a fork and pour the lemon filling on top.
  5. Bake again for 20 to 25 minutes until the filling is set and slightly golden.
  6. Allow the bars to cool at room temperature for about 2 hours, then chill in the fridge for an additional 2 hours before cutting.
  7. Lift the dessert from the pan using the parchment overhang, dust with powdered sugar, cut into squares, and enjoy!

Notes

Serve with a sprinkle of powdered sugar or paired with fresh berries. Store leftovers in an airtight container in the fridge for about a week.
