Ingredients
Shortbread Crust
- 2 cups all-purpose flour
- 1 cup unsalted butter, softened
- 1/2 cup powdered sugar, plus more for garnish
- 1/2 teaspoon salt
Lemon Filling
- 1 tablespoon lemon zest
- 2/3 cup lemon juice (about 4-5 lemons)
- 4 large eggs
- 2 cups granulated sugar
Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 350℉ (175℃). Fully line a 9×13 inch glass or ceramic baking dish with parchment paper to ensure easy removal of the bars later.
- Make the Shortbread Crust: In a mixing bowl, combine the all-purpose flour, softened unsalted butter, 1/2 cup powdered sugar, and salt. Use an electric mixer to blend until a thick dough forms. Press the dough evenly into the bottom of the prepared baking pan, making sure to cover the entire base, even if the dough seems initially insufficient.
- Bake the Crust: Place the crust in the preheated oven and bake for 20-23 minutes. Bake until it is slightly golden and firm, taking care to ensure the center is fully cooked and not doughy.
- Prepare Lemon Zest and Juice: While the crust bakes, zest the lemons and then juice them, ensuring you remove any seeds. Measure about 2/3 cup of juice by squeezing approximately 4-5 lemons, then strain to avoid pulp and seeds.
- Make the Lemon Filling: In a clean bowl, use an electric mixer to combine the eggs, granulated sugar, lemon zest, and lemon juice. Mix thoroughly until the sugar dissolves and the mixture is smooth.
- Pour Filling over Hot Crust: When the crust is done baking, remove it from the oven and immediately pour the lemon filling over the hot crust. Smooth the surface with a spatula if needed.
- Bake Lemon Bars: Return the pan to the oven and bake for an additional 25-30 minutes, or until the lemon filling is set. To test, gently shake the pan side to side; the center should not be liquidy. The top of the filling will develop a slight crust and the edges will caramelize lightly.
- Cool Completely: Remove from the oven and allow the bars to cool in the pan at room temperature for at least one hour. Then refrigerate for at least 2 hours or preferably overnight for best texture and flavor.
- Cut and Serve: Using the parchment paper, lift the bars out onto a cutting board. Trim the edges with a sharp knife for a clean look. Slice into approximately 2 1/2 inch squares. Generously dust the tops with powdered sugar using a fine mesh sieve for even coverage. Serve chilled for a refreshing treat.
Notes
- Ensure the crust is baked thoroughly and is firm to support the lemon filling without becoming soggy.
- Remove all seeds from the lemon juice to avoid bitterness and unpleasant texture.
- For easy slicing, chill the bars overnight to help the lemon filling set firmly.
- Using parchment paper prevents the bars from sticking and facilitates easy removal from the pan.
- These lemon bars are best served cold but can be brought to room temperature if preferred.
