Ingredients
  

For the Buttery Shortbread Crust
  • 1 cup unsalted butter softened
  • 1/2 cup granulated sugar
  • 2 cups all-purpose flour
  • 1/4 teaspoon salt
For the Tangy Lemon Filling
  • 4 large eggs
  • 1 1/2 cups granulated sugar
  • 1/4 cup all-purpose flour
  • 2 tablespoons cornstarch
  • 2/3 cup freshly squeezed lemon juice
  • 1 tablespoon lemon zest
  • 1/4 teaspoon salt
For Finishing
  • 2 tablespoons powdered sugar for dusting
  • Thin lemon slices for garnish optional

Method
 

  1. Preheat the oven to 350°F and line a 9x13-inch baking pan with parchment paper so the bars can be removed easily after baking.
  2. Cream the butter and sugar together until smooth, then mix in the flour and salt until a soft dough forms. Press the dough evenly into the pan and bake until lightly golden around the edges.
  3. Whisk together the eggs, sugar, flour, cornstarch, lemon juice, lemon zest, and salt until completely smooth with no lumps remaining in the filling.
  4. Pour the lemon mixture over the hot baked crust and return the pan to the oven. Bake until the center looks mostly set with a slight wobble.
  5. Cool the bars at room temperature first, then refrigerate them until fully chilled so the filling firms up properly before slicing.
  6. Dust the chilled lemon bars with powdered sugar, slice carefully using a sharp knife, and serve cold or slightly cool for the best flavor.

Notes

  • Always use freshly squeezed lemon juice because it provides brighter flavor and better aroma than bottled juice, which can taste overly acidic and flat.
  • Chill the lemon bars completely before cutting so the filling stays smooth and the slices hold their shape without breaking apart.
  • Wipe the knife clean between each cut because sticky filling and crumbs can quickly make the bars look messy around the edges.
  • Avoid overbaking the filling since eggs continue cooking as the bars cool. Removing them slightly early keeps the texture creamy instead of rubbery.
  • Dust the powdered sugar on top shortly before serving because moisture from refrigeration can cause the sugar to dissolve into the surface.
