Key Ingredients
Unsalted Butter
Melted butter forms the base of the shortbread crust and gives it a rich, buttery flavor. Unsalted butter also lets you control the amount of salt in the recipe.
Granulated Sugar
Sugar is used in both the crust and lemon filling. It balances the tartness of the fresh lemon juice and helps the filling set as it bakes.
All-Purpose Flour
Flour gives the shortbread crust structure and also helps thicken the lemon filling. For accurate measuring, spoon the flour into your measuring cup and level it rather than scooping directly from the bag.
Fresh Lemons
Fresh lemons provide both the juice and zest. You will need about 3 to 4 medium lemons for this recipe. Freshly squeezed juice gives the bars a brighter flavor than bottled lemon juice.
Eggs
Eggs give the lemon filling structure and richness. They help the filling set into a smooth, sliceable layer as it bakes.
Step-by-Step Instructions
1. Bake the Shortbread Crust
Preheat the oven to 350°F (177°C).
Line an 8×8-inch metal baking pan with parchment paper, leaving an overhang on two sides. Lightly spray the parchment and exposed sides with nonstick cooking spray.
In a medium bowl, whisk together the melted butter, granulated sugar, vanilla extract, and salt. Stir in the flour until a soft dough forms.
Press the dough evenly into the bottom of the prepared pan.
Bake for 18 to 20 minutes, or until the edges are lightly golden brown.
2. Prepare the Lemon Filling
While the crust is baking, whisk the sugar and flour together in a large bowl.
Add the eggs, fresh lemon juice, and lemon zest. Whisk until smooth and well combined.
Some small bubbles may form while whisking. This is normal.
3. Bake the Lemon Layer
Remove the crust from the oven and immediately pour the lemon filling over the hot crust.
Reduce the oven temperature to 325°F (163°C).
Return the pan to the oven and bake for 18 to 22 minutes, or until the edges are set and the center has only a slight jiggle when the pan is gently moved.
The filling will continue to firm up as it cools and chills, so avoid baking it until completely firm in the oven.
4. Cool and Chill
Place the pan on a wire rack and let the lemon bars cool completely at room temperature.
Once cooled, cover the pan and refrigerate for at least 2 hours, or until the filling is firm.
Use the parchment overhang to lift the bars from the pan.
For clean slices, use a long, sharp knife and wipe the blade clean between cuts. Dust with powdered sugar just before serving.
Tips for Success
Use Fresh Lemons
Freshly squeezed lemon juice and fresh zest give these bars their best citrus flavor. Always use freshly squeezed lemon juice! Bottled lemon juice lacks the bright acidity and leaves an unpleasant metallic aftertaste.
Use a Metal Baking Pan
An 8×8-inch metal pan works well for this recipe and helps the crust and filling bake evenly. Glass and ceramic pans can behave differently in the oven, so the baking time may need to be adjusted.
Don’t Overbake the Filling
The center should still have a slight jiggle when the pan is gently moved. The filling will continue to set while the bars cool and chill.
Chill Before Slicing
Give the bars enough time to chill completely before cutting. Slicing them while warm can make the filling too soft and difficult to cut neatly.
Use a Parchment Sling
Leave several inches of parchment overhang on two sides of the pan. Once the bars are chilled, the parchment makes it much easier to lift the entire dessert from the pan.
FAQ
Why are my lemon bars soggy?
The crust may not have baked long enough. Bake until the edges are lightly golden, then pour the filling over the hot crust.
Why is there a thin white layer on top?
Small air bubbles can rise to the surface during baking. This is normal and does not affect the flavor.
Can I use bottled lemon juice?
No, always use freshly squeezed lemon juice! Bottled lemon juice lacks the bright acidity needed for lemon curd and leaves an unpleasant metallic aftertaste.
Can I double this recipe?
A double batch can be baked in a 9×13-inch pan. Baking time may vary, so check the crust and filling for doneness.
Can I make lemon bars ahead of time?
Yes. Make them up to 1 day ahead and keep them covered in the refrigerator.
How should I store lemon bars?
Store covered in the refrigerator for up to 5 days. Add powdered sugar just before serving.

- Whisk Filling: While the crust bakes, whisk sugar and flour together in a large bowl. Add eggs, fresh lemon juice, and lemon zest. Whisk vigorously until smooth.
- Bake Lemon Layer: Remove crust from oven and pour filling directly onto the hot crust. Reduce oven temperature to 325°F (163°C). Bake for 18–22 minutes, or until the edges are set and the center has a slight jiggle when the pan is gently moved.

Notes
- Use Fresh Lemons: Freshly squeezed lemon juice and fresh zest provide the best flavor. Always use freshly squeezed lemon juice! Bottled lemon juice lacks bright acidity and leaves an unpleasant metallic aftertaste.
- Pour Filling Over a Hot Crust: Pour the lemon filling over the crust immediately after it comes out of the oven. This allows the crust and filling to continue baking together without cooling the crust first.
- Pan Selection: A metal 8×8-inch baking pan is recommended for this recipe because it heats efficiently and gives the crust a good texture. Glass or ceramic pans may require different baking times.
