Directions

Preheat the oven to 350°F (175°C). Grease or line an 8×8-inch or 9×9-inch baking pan with parchment paper.
In a mixing bowl, combine the flour, sugar, salt, and softened butter until a crumbly dough forms.
Press the dough evenly into the bottom of the prepared pan.

While the crust bakes, whisk together the eggs, sugar, lemon juice, lemon zest, flour, baking powder, and salt until smooth.
Pour the lemon filling over the hot crust immediately after removing it from the oven.
Return the pan to the oven and bake for 20–25 minutes, or until the filling is set and no longer jiggles in the center.
Allow the lemon bars to cool completely at room temperature.

Storage/Reheating

Wrap individual bars tightly in plastic wrap and place them in a freezer-safe container. Thaw overnight in the refrigerator before serving.

FAQs

Why do my Lemon Bars have a soft center?

A slightly soft center is normal, but the filling should be fully set before removing the bars from the oven. They will continue to firm up as they cool and chill.

Can I use bottled lemon juice?

Fresh lemon juice is strongly recommended because it provides brighter flavor, but bottled lemon juice can be used if necessary.

Why should I chill the bars before cutting?

Chilling allows the filling to fully set, making it much easier to cut clean, even squares.

Can I make Lemon Bars ahead of time?

Yes. They’re an excellent make-ahead dessert and often taste even better after chilling overnight.

How do I prevent a soggy crust?

Bake the crust until lightly golden before adding the filling, and avoid underbaking it.

Can I freeze Lemon Bars?

Yes. Freeze them for up to 3 months and thaw them in the refrigerator before serving.

Why is powdered sugar added just before serving?

Powdered sugar can dissolve into the moist lemon filling over time, so adding it just before serving keeps the bars looking fresh.

Can I double this recipe?

Absolutely. Double the ingredients and bake in a 9×13-inch pan, increasing the baking time slightly if needed.

What pairs well with Lemon Bars?

Fresh berries, whipped cream, vanilla ice cream, iced tea, coffee, or sparkling lemonade all complement their bright citrus flavor.

Can I make these dairy-free?

Yes. Substitute the butter in the crust with a high-quality dairy-free butter alternative.
