ingredients

For the Shortbread Crust:

• All-purpose flour
• Unsalted butter (cold and cubed)
• Granulated sugar
• Salt

For the Lemon Filling:

• Eggs
• Granulated sugar
• All-purpose flour
• Fresh lemon juice
• Lemon zest
• Baking powder (optional, for a lighter filling)
• Powdered sugar (for dusting)

directions

1. Prepare the Crust: Preheat the oven to 350°F (175°C). Line a baking pan with parchment paper. In a bowl, mix flour, sugar, and salt. Cut in the cold butter until the mixture resembles coarse crumbs. Press evenly into the bottom of the prepared pan. Bake for 15–20 minutes until lightly golden.
2. Make the Filling: While the crust bakes, whisk together eggs, granulated sugar, flour, lemon juice, zest, and baking powder (if using) in a bowl until smooth and combined.
3. Bake Again: Pour the filling over the warm crust and return to the oven. Bake for 20–25 minutes, or until the center is set and the top is lightly golden.
4. Cool and Finish: Allow to cool completely in the pan. Once cooled, dust with powdered sugar.
5. Serve: Cut into squares or bars and serve chilled or at room temperature.

FAQs

Can I use bottled lemon juice instead of fresh?

Fresh lemon juice is highly recommended for the best flavor, but bottled juice can be used in a pinch.

Why did my lemon bars crack on top?

Overbaking or rapid cooling can cause cracking. Bake just until set and cool gradually.

Can I make lemon bars ahead of time?

Yes, they store well and taste even better after chilling for a few hours or overnight.

How do I know when the filling is done?

The center should be just set and not jiggly. A slight golden color on top is normal.

Can I double the recipe?

Yes, double the ingredients and use a larger pan, adjusting the baking time as needed.

How do I get clean cuts?

Chill completely and use a sharp knife wiped clean between slices for neat edges.

Do I need to refrigerate lemon bars?

Yes, due to the egg-based filling, lemon bars should be stored in the refrigerator.

Can I make these gluten-free?

Yes, substitute the flour with a gluten-free all-purpose flour blend.

What size pan should I use?

An 8×8-inch or 9×9-inch square baking pan is ideal for standard-sized lemon bars.

Can I add a meringue topping?

Yes, but it should be added and baked briefly after the lemon filling is set.
