Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the crust:

1 cup unsalted butter, softened

1/2 cup powdered sugar

2 cups all-purpose flour

1/4 teaspoon salt

For the lemon filling:

4 large eggs

1 3/4 cups granulated sugar

1/4 cup all-purpose flour

1/3 cup fresh lemon juice

1 tablespoon lemon zest

1 teaspoon baking powder

1/4 teaspoon salt

Extra powdered sugar for dusting

Directions

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan or line it with parchment paper for easier removal.

In a large mixing bowl, combine the softened butter and powdered sugar until smooth and creamy. Add the flour and salt, mixing until a soft dough forms.

Press the dough evenly into the bottom of the prepared baking pan. Use your hands or the back of a measuring cup to create an even layer.

Bake the crust for 18 to 20 minutes, or until lightly golden around the edges.

While the crust is baking, prepare the lemon filling. In a medium bowl, whisk together the eggs and granulated sugar until smooth. Add the flour, lemon juice, lemon zest, baking powder, and salt. Continue whisking until fully combined and slightly frothy.

Pour the lemon mixture over the warm baked crust immediately after removing it from the oven.

Return the pan to the oven and bake for an additional 20 to 25 minutes, or until the center is set and no longer jiggles.

Allow the lemon bars to cool completely at room temperature. Then refrigerate for at least 2 hours for cleaner slices.

Dust the top with powdered sugar before cutting into squares and serving.

Variations

Add a little extra lemon zest for a stronger citrus flavor.

Mix in a tablespoon of orange juice with the lemon juice for a sweeter citrus blend.

Top the bars with fresh berries before serving for extra freshness.

Use lime juice instead of lemon juice for a different tangy dessert variation.

For a richer crust, add a teaspoon of vanilla extract to the dough.

You can also sprinkle shredded coconut over the crust before adding the filling for extra texture.

Storage/Reheating

Store lemon bars in an airtight container in the refrigerator for up to 5 days. Keep them chilled to maintain the best texture and flavor.

To freeze, place the bars in a single layer on a baking sheet until firm, then transfer them to a freezer-safe container. Freeze for up to 3 months.

Thaw frozen lemon bars overnight in the refrigerator before serving.

These bars are best served cold or slightly chilled, so reheating is usually unnecessary. If preferred, let them sit at room temperature for about 15 minutes before serving.

FAQs

Why are my lemon bars runny?

The filling may need more baking time. Bake until the center is fully set and no longer jiggles.

Can I use bottled lemon juice?

Fresh lemon juice is recommended for the best flavor, but bottled lemon juice can work if needed.

How do I get clean slices?

Chill the bars completely before cutting and wipe the knife clean between slices.

Can I make lemon bars ahead of time?

Yes, lemon bars are perfect for making a day in advance since they taste even better chilled.

Why did my crust crack?

Overmixing or pressing the crust too firmly can sometimes cause cracking.

Can I freeze lemon bars?

Yes, they freeze very well for up to 3 months in an airtight container.

Do lemon bars need refrigeration?

Yes, because of the egg-based filling, they should be stored in the refrigerator.

Can I use gluten-free flour?

Yes, a gluten-free all-purpose flour blend can be substituted successfully.

Why are my lemon bars too tart?

You can slightly reduce the lemon juice or add a little more sugar for a sweeter flavor.

What is the best pan to use?

A metal 9×13-inch baking pan works best because it bakes the crust and filling evenly.
