Ingredients
- 2 cups all-purpose flour
- 1 cup butter, softened
- ½ cup white sugar (for the crust)
- 1 ½ cups white sugar (for the filling)
- ¼ cup all-purpose flour
- 4 large eggs
- Juice of 2 lemons
- Powdered sugar, for dusting (optional)
Instructions
- Step 1: Preheat your oven to 350°F (175°C). In a medium bowl, blend 2 cups flour, softened butter, and ½ cup sugar until the mixture is well combined to form the crust.
- Step 2: Press the crust mixture evenly into the bottom of an ungreased 9×13-inch pan. Bake for about 15 minutes, or until firm and golden.
- Step 3: While the crust bakes, whisk together the remaining 1 ½ cups sugar and ¼ cup flour in a medium bowl. Add the eggs and lemon juice, whisking until smooth.
- Step 4: Pour the lemon filling over the warm crust and return the pan to the oven. Bake for an additional 20 minutes.
- Step 5: Remove from oven and allow to cool completely so the bars can set. Once cooled, dust with powdered sugar if desired, then cut into squares and serve.
Tips & Variations
- Add lemon zest to the filling for an extra burst of citrus flavor.
- For a twist, substitute limes for lemons and add a drop of green food coloring to create pale green bars.
- Use chilled whipped cream as a topping for an elegant presentation.
Storage
Store lemon bars in an airtight container in the refrigerator for up to seven days. Because of the egg-rich filling, refrigeration is necessary to keep them fresh. To freeze for longer storage, wrap the bars tightly in plastic wrap, then foil, and freeze for up to four months. Thaw overnight in the refrigerator before serving.

Ingredients
Crust:
- 2 cups all-purpose flour
- 1 cup butter, softened (2 sticks)
- ½ cup white sugar
Filling:
- 1 ½ cups white sugar
- ¼ cup all-purpose flour
- 4 large eggs
- Juice of 2 lemons (about ¼ cup)
For serving:
- Powdered sugar, for dusting
Instructions
- Preheat the oven: Set your oven to 350 degrees F (175 degrees C) to prepare for baking the crust.
- Make the crust: In a medium bowl, mix 2 cups flour, 1 cup softened butter, and ½ cup sugar until the dough is well combined and crumbly.
- Press and bake the crust: Press the crust mixture evenly into the bottom of an ungreased 9×13-inch baking pan. Bake for about 15 minutes until the crust is firm and golden.
- Prepare the filling: While the crust bakes, whisk together 1 ½ cups sugar and ¼ cup flour in a medium bowl. Add the eggs, whisking until smooth, then stir in the fresh lemon juice until fully combined.
- Pour filling over crust: Carefully pour the lemon filling over the hot, baked crust, spreading it evenly.
- Bake the lemon bars: Return the pan to the oven and bake for an additional 20 minutes until the filling is set but still slightly jiggly in the center.
- Cool completely: Remove the pan from the oven and let the bars cool completely at room temperature; the filling will firm up as they cool.
