1-Preheat and Prep Your Pan: First, preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper. This step makes removal easy and prevents sticking, saving you time later. Press the dough firmly for an even base that bakes up golden.

2-Mix and Bake the Crust: Second, prepare the crust by combining all-purpose flour, sugar, and melted unsalted butter in a bowl. Mix until a crumbly dough forms, then press it evenly into the bottom of your prepared pan. Bake for 15-20 minutes until it’s lightly golden, creating a sturdy foundation for the filling.

3-Whip Up the Filling: While the crust bakes, whisk together eggs, granulated sugar, fresh lemon juice, flour, and a pinch of salt to make the filling. This mixture should be smooth and well-blended for the best results. Pour it over the warm crust once it’s ready, ensuring even coverage for uniform baking.

4-Bake the Full Bars: Next, return the pan to the oven for an additional 20-25 minutes. The filling should set but still be slightly jiggly in the center, signaling it’s done without overcooking. Let it cool on a wire rack before chilling, as this helps the flavors meld together nicely.

5-Cool and Serve: After baking, remove the pan from the oven and let it cool completely on a wire rack. Then, refrigerate for at least 2 hours to firm up the bars, making them easier to cut. Finally, dust with powdered sugar, slice into squares, and serve for a treat that’s ready to share at any gathering.
