This recipe for a 9×13-inch pan yields a bright, sweet-tart treat that’s ideal for gatherings or a refreshing finish to any meal. With simple ingredients and straightforward steps, you can create a luscious lemon bar that impresses every time.

Ingredients

1 cup (2 sticks) unsalted butter, softened
1/2 cup granulated sugar
2 cups all-purpose flour, divided
1/4 teaspoon salt
4 large eggs
1 1/2 cups granulated sugar
1/4 cup all-purpose flour
1/2 cup freshly squeezed lemon juice (from about 2-3 lemons)
Optional: powdered sugar for dusting

Instructions

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.

Make the crust: In a medium bowl, cream together the softened butter and 1/2 cup sugar until light and fluffy. Add 1 1/2 cups flour and salt; mix until just combined. Press this mixture evenly into the bottom of the prepared pan to form the crust.
Bake the crust: Place the pan in the preheated oven and bake for 20-25 minutes, or until the edges are golden. Remove from oven and set aside.
Prepare the lemon filling: In a large bowl, whisk together the eggs, 1 1/2 cups sugar, and 1/4 cup flour until smooth. Stir in the lemon juice until well combined.

Pour the filling: Carefully pour the lemon mixture over the hot crust, spreading evenly.
Bake again: Return the pan to the oven and bake for an additional 20-25 minutes, or until the filling is set and slightly firm around the edges.
Cool and chill: Allow the lemon bars to cool completely in the pan on a wire rack. Once cooled, refrigerate for at least 2 hours to set fully.

Serve: Use the parchment overhang to lift the bars out of the pan. Cut into squares and dust with powdered sugar if desired before serving.

Tips

Substitutions: For a dairy-free version, use coconut oil or dairy-free butter in the crust. Lemon juice can be replaced with bottled lemon concentrate if fresh lemons aren’t available.
Storage: Store lemon bars in an airtight container in the refrigerator for up to 4 days. To keep them fresh, cover tightly with plastic wrap or foil.

Prevent cracks: Avoid overbaking the filling; it should still slightly jiggle in the center when removed from the oven. Overbaking causes cracks and a dry texture.
Enhance flavor: Add a teaspoon of lemon zest to the filling for an extra burst of citrus aroma and flavor.

Serving Suggestions

Serve lemon bars chilled or at room temperature. They pair beautifully with a dollop of whipped cream or a scoop of vanilla ice cream. For a more elegant presentation, garnish with fresh lemon slices or a sprig of mint.

Variations

Berry Lemon Bars: Swirl in a tablespoon of raspberry or blueberry jam into the lemon filling before baking for a fruity twist.
Coconut Lemon Bars: Add 1/4 cup shredded coconut to the crust for a tropical flavor.
Gluten-Free Lemon Bars: Substitute the all-purpose flour with a gluten-free flour blend in both the crust and filling.

Storage and Reheating

Refrigerate lemon bars in an airtight container for up to 4 days. For longer storage, freeze the bars in a single layer on a baking sheet, then transfer to a freezer-safe container. They can be frozen for up to 2 months. To reheat, thaw in the refrigerator and enjoy cold or bring to room temperature for serving. If reheating slightly, do so in the microwave at 10-15 second intervals, but be careful not to overheat to prevent melting or cracking.

Frequently Asked Questions

Can I use bottled lemon juice instead of fresh?

Yes, bottled lemon juice can be used as a convenient substitute. Use an equal amount, but note that fresh lemon juice provides a brighter, more vibrant flavor that enhances the overall brightness of the bars.

How do I know when the lemon filling is set?

The filling is ready when it appears slightly firm around the edges and a toothpick inserted near the center comes out with moist crumbs. It should jiggle slightly in the middle but not be liquid.

Can I make lemon bars ahead of time?

Absolutely. Lemon bars can be prepared a day in advance. Store them covered in the refrigerator to keep them fresh. Just dust with powdered sugar before serving if desired.

What is the best way to cut the lemon bars?

Use a sharp, clean knife to cut the bars. For cleaner cuts, wipe the knife clean between slices and cut when the bars are fully chilled. Using a plastic or serrated knife can also help prevent crumbling.

Can I double the recipe and bake it in a larger pan?

Doubling the recipe can be done, but you’ll need a larger pan, such as a 12×17-inch sheet pan, to accommodate the increased amount of batter. Adjust baking times accordingly, and keep an eye on the filling to prevent overbaking.

What makes lemon bars crack on top?

Cracking often results from overbaking or baking at too high a temperature. Ensuring the filling is just set and removing the bars from the oven promptly helps prevent cracks. Also, letting the bars cool slowly in the pan can reduce surface cracks.
