Let’s get our aprons on and bake something wonderful.

The Magic of Great Ingredients

With a simple recipe like this, the quality of your ingredients really shines through. This is where you can let seasonal, local produce be the star.

• Fresh Lemons: This is non-negotiable. The bright, zesty flavor of fresh lemons is the heart and soul of this dessert. Bottled lemon juice simply cannot compare. Look for lemons that feel heavy for their size, a sign that they are full of juice. If you can find them at a local farmers market, even better. The zest is just as important as the juice, as it contains all the fragrant oils that give the bars their incredible aroma.
• Real Butter: For the shortbread crust, you want to use real, unsalted butter. It provides the rich flavor and tender, melt-in-your-mouth texture that makes the crust so irresistible.
• Eggs: These provide the structure for the lemon filling, creating that smooth, custard-like consistency.
• Flour and Sugar: We'll use all-purpose flour for both the crust and the filling. Granulated sugar provides the sweetness to balance the tart lemons, and a dusting of powdered sugar on top is the classic finishing touch.

Part 1: The Perfect Buttery Shortbread Crust

The foundation of a great lemon bar is a sturdy yet tender shortbread crust. It needs to be robust enough to hold the luscious filling but delicate enough to crumble beautifully when you take a bite. Our method is simple and foolproof.

This crust is made with just a few ingredients: butter, sugar, flour, and a pinch of salt. The key is to use cold butter and not to overwork the dough. We're looking for a texture that resembles coarse crumbs before pressing it into the pan. This creates little pockets of butter that will melt during baking, resulting in a wonderfully flaky and tender base.

We will also pre-bake the crust before adding the filling. This step is crucial. It ensures the crust stays crisp and doesn't become soggy from the wet filling. A perfectly baked crust is the crunchy, buttery counterpart to the smooth, zesty lemon layer.

Part 2: The Luscious Lemon Filling

This is where the bright, sunny flavor comes to life. The filling is a simple mixture of eggs, sugar, fresh lemon juice, lemon zest, and a little bit of flour. The flour acts as a thickener, helping the filling to set into a perfect, sliceable custard.

The most important tip for a smooth, perfect filling is to whisk your ingredients together thoroughly. You want to make sure the eggs are completely broken up and incorporated with the sugar before adding the lemon juice. This ensures a uniform texture without any eggy bits. And don't be shy with the lemon zest. It adds a powerful punch of lemon aroma that makes these bars truly special.

This recipe will guide you through creating classic, delicious lemon bars that are bursting with flavor.

Prep Time: 20 minutes
Bake Time: 40-45 minutes
Yield: 16 bars
Category: Desserts & Bakes

Ingredients

For the Shortbread Crust:

• 1 cup (2 sticks) unsalted butter, cold and cut into cubes
• ½ cup granulated sugar
• 2 cups all-purpose flour
• ¼ teaspoon salt

For the Lemon Filling:

• 1 ½ cups granulated sugar
• ¼ cup all-purpose flour
• 4 large eggs, at room temperature
• ⅔ cup fresh lemon juice (from about 3-4 lemons)
• 1 tablespoon finely grated lemon zest
• Powdered sugar, for dusting

Instructions

1. Prepare for Baking: Preheat your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides. This will make it easy to lift the bars out of the pan later.
2. Make the Crust: In the bowl of a stand mixer with the paddle attachment, or in a large bowl with a hand mixer, combine the cold butter cubes, granulated sugar, flour, and salt. Mix on low speed until the mixture resembles coarse, sandy crumbs.
3. Press and Pre-Bake: Dump the crumbs into your prepared baking pan. Use your fingers or the bottom of a measuring cup to press the mixture firmly and evenly into the bottom of the pan. Bake for 20-25 minutes, or until the edges are lightly golden brown.
4. Prepare the Filling: While the crust is baking, prepare the lemon filling. In a large bowl, whisk together the granulated sugar and the flour. Add the eggs and whisk until the mixture is smooth and well combined.
5. Add the Lemon: Stir in the fresh lemon juice and lemon zest until everything is incorporated.
6. Bake the Bars: Once the crust is out of the oven, reduce the oven temperature to 325°F (160°C). Pour the lemon filling evenly over the hot crust.
7. Final Bake: Carefully return the pan to the oven and bake for another 20-25 minutes. The filling is done when it is just set and no longer jiggles in the center. The edges may be slightly puffed.
8. Cool Completely: Let the lemon bars cool completely in the pan on a wire rack for at least 1 hour. Then, transfer them to the refrigerator to chill for at least 2 more hours. This chilling step is essential for the filling to set properly, so you can make clean cuts.
9. Slice and Serve: Once chilled, use the parchment paper overhang to lift the bars out of the pan. Dust generously with powdered sugar, slice into squares, and serve.

Tips for Perfect Lemon Bars

• Use Fresh Lemons: It bears repeating. The flavor from fresh juice and zest is what makes these bars shine.
• Don't Overbake the Filling: You want to pull the bars from the oven when the center is just barely set. It will continue to firm up as it cools. Overbaking can lead to a rubbery texture.
• Chill for Clean Slices: Don't rush the cooling and chilling process. A well-chilled bar is key to getting those picture-perfect squares.
• Troubleshooting Bubbles: If you notice bubbles on the surface of your filling after baking, don't worry. This is normal and happens as the eggs cook. A generous dusting of powdered sugar will hide any imperfections.

Storage and Serving Ideas

• Storage: Lemon bars should be stored in an airtight container in the refrigerator. They will keep well for up to a week. I actually think they taste even better on the second day, once the flavors have had more time to meld.
• Serving: These bars are a perfect dessert for picnics, potlucks, or any gathering. They are a wonderful comfort food treat to enjoy with a cup of tea or coffee. Their bright flavor also makes them a fantastic dessert after a rich meal.
