Instructions

Make the crust:

Set your oven to 350°F and lightly butter a 9-by-13-inch baking dish. (For a thicker base, you can use a 9x9 pan instead.)
Combine the flour, sugar, and salt in a bowl.
Add the cubed butter and work it into the dry mixture using a pastry cutter until it forms fine, crumb-like bits.
Press the mixture evenly into the prepared pan.
Bake for about 20 minutes, or until the edges turn lightly golden.

Prepare the filling:

Mix the sugar and flour together in a bowl.
Add the eggs and whisk until smooth.
Stir in the lemon zest and juice until fully blended.
Pour the lemon mixture over the baked crust.

Bake and chill:

Return the pan to the oven and bake for 20–30 minutes, until the filling is set and no longer wobbly.
Let the bars cool, then refrigerate for at least 2 hours.
Before slicing, dust the top with powdered sugar.

Storage

Keep any leftover bars refrigerated.

How do I know when they’re done?
You’re looking for a set center with no jiggle. Give the pan a gentle shake—if it wobbles, it needs more time. If it’s firm, you’re good to go.
Do I really have to refrigerate them?
Yes, you do. That creamy lemon layer is egg-based, so chilling helps it fully set and keeps everything fresh and sliceable.
Can I make these ahead of time?
Absolutely. And honestly? They’re even better the next day. The flavor settles, the texture firms up, and slicing becomes way easier.
Why did my lemon bars crack or turn rubbery?
Most likely overbaked. Pull them out as soon as the center is just set—no need to wait for full firmness in the oven.
How do I get clean, bakery-style slices?
Sharp knife, wipe between cuts, and go slow. Bonus tip: chill them well first—it makes a huge difference.
