Prepare the Shortbread Crust. Preheat your oven to 350°F and grease an 8x8-inch baking pan. Line it with parchment paper for easy removal. In a medium bowl, mix the flour, softened butter, and granulated sugar until crumbly. Press the mixture evenly into the bottom of the prepared pan. Bake the crust for 15-18 minutes or until lightly golden. Let it cool while you prepare the filling.
Make the Lemon Filling. In a large bowl, whisk the eggs, granulated sugar, lemon juice, and lemon zest until well combined.Sift in the flour and mix until smooth. This will ensure the filling sets beautifully.
Assemble and Bake. Pour the lemon filling over the cooled crust, spreading it evenly. Bake for 20-25 minutes or until the filling is set and no longer jiggles in the center. Let the bars cool completely before removing them from the pan.
Garnish and Serve. Dust the cooled lemon squares generously with powdered sugar for a stunning finish. Slice into squares and serve. Enjoy their zesty, sweet perfection!
