These easy lemon bars feature a buttery shortbread crust topped with a bright, tangy lemon filling. Perfect for sharing, snacking, or serving as a simple homemade dessert.
Prepare an 8" x 8" baking pan by lightly spraying it with flour-based baking spray or lining it with parchment paper.
Combine the butter, flour, and powdered sugar in a mixing bowl until the mixture is crumbly. Press evenly into the prepared pan and chill.
Preheat the oven to 350°F (175°C). Bake the chilled crust for 15-18 minutes, until lightly golden brown.
In a clean bowl, whisk together the lemon juice, lemon zest, eggs, granulated sugar, and sifted flour until smooth.
Pour the lemon filling over the baked crust and spread evenly.
Bake for 25-30 minutes, until the filling is set but still slightly jiggly in the center.
Cool completely at room temperature, then refrigerate for at least 1 hour.
Dust with powdered sugar before serving and cut into bars.
Notes
Use freshly squeezed lemon juice for the best flavor. For cleaner cuts, chill the bars thoroughly and use a sharp knife. Store covered in the refrigerator for up to one week or freeze for up to three months.
