Total Time: 1 hour 10 minutes
Servings: 9-12
Yield: 9-12 Lemon Bars
Dietary Type: Not specified

Ingredients

For the Crust:

¾ cup (1 ½ sticks) butter
2 cups all-purpose flour
½ cup white sugar

For the Filling:

3 eggs
1 cup white sugar
2 tablespoons white sugar
3 tablespoons flour
⅓ teaspoon baking powder
6 tablespoons fresh lemon juice
3 tablespoons lemon zest

Equipment Needed

8-inch square baking pan
Mixing bowls
Fork
Mixer (hand or stand)
Measuring cups and spoons
Lemon zester
Lemon juicer
Powdered sugar for dusting (optional)

Instructions

Preheat your oven to 350°F (175°C). Make sure your oven rack is positioned in the center for even baking.
Prepare the Crust: In a mixing bowl, combine the butter, all-purpose flour, and ½ cup of white sugar. Using a fork or a pastry blender, cut the butter into the flour mixture until it resembles coarse crumbs. The mixture should hold together when pressed.
Press the Crust: Press the crumbly mixture evenly into the bottom of an ungreased 8-inch square cake pan. Ensure the crust is compact and reaches all corners of the pan.
Bake the Crust: Bake the crust in the preheated oven for 20 minutes. Keep a close eye on it; you want it lightly golden but not browned. Remove the pan from the oven and set aside.
Prepare the Filling: While the crust is baking, prepare the lemon filling. In a separate mixing bowl, combine the eggs, 1 cup of white sugar, 2 tablespoons of white sugar, flour, and baking powder.
Mix the Filling: Use a mixer (hand or stand) to beat the ingredients together until well combined and smooth. Be careful not to overmix, as this can lead to a tough filling.
Add the Lemon: Add the fresh lemon juice and lemon zest to the filling mixture. Mix until just combined. The batter will be quite liquid.
Pour the Filling: Pour the lemon filling evenly over the pre-baked crust.
Bake the Bars: Return the pan to the oven and bake for an additional 30 minutes. The filling should be set but still slightly jiggly in the center. A toothpick inserted near the center should come out with moist crumbs attached, not wet batter.
Cool and Dust: Remove the lemon bars from the oven and let them cool completely in the pan on a wire rack. Once cooled, dust generously with powdered sugar if desired.
Cut and Serve: Once fully cooled, cut the lemon bars into squares or rectangles. Use a sharp knife and wipe it clean between cuts for neat slices.

Expert Tips & Tricks

Use Room Temperature Butter: For the best crust texture, use butter that is softened but still cool. It should be pliable but not greasy.
Fresh Lemon is Key: Using freshly squeezed lemon juice and zest is essential for the most vibrant lemon flavor. Avoid bottled juice if possible.
Don’t Overbake: Overbaking the lemon bars will result in a dry, cracked filling. They should be slightly jiggly when removed from the oven, as they will continue to set as they cool.
Zest Wisely: When zesting the lemons, be careful to only zest the yellow part of the peel, avoiding the white pith underneath, which can be bitter.
Prevent Soggy Crust: For an extra-crisp crust, you can lightly brush it with a beaten egg white before pouring in the filling.
For extra Lemon Zest flavor: Add additional lemon zest to both the crust and the filling.

Serving & Storage Suggestions

Lemon bars are best served chilled or at room temperature. They can be served as a dessert, a snack, or as part of a tea party spread. Garnish with fresh berries or a sprig of mint for an elegant presentation.

Store leftover lemon bars in an airtight container in the refrigerator for up to 5 days. They can also be frozen for up to 2 months. To freeze, cut the bars into individual squares and wrap them tightly in plastic wrap before placing them in a freezer-safe container. Thaw in the refrigerator before serving.

FAQs (Frequently Asked Questions)

Q: Why is my lemon bar filling too runny?
A: Ensure you’ve accurately measured the ingredients, especially the flour. Overmixing can also contribute to a runny filling.

Q: Can I use bottled lemon juice instead of fresh?
A: While you can, fresh lemon juice provides the best and most vibrant flavor. Bottled juice often lacks the brightness of fresh lemons.

Q: How do I prevent the crust from burning?
A: Keep a close eye on the crust while it’s baking. If it starts to brown too quickly, tent the pan with aluminum foil.

Q: Can I make these lemon bars ahead of time?
A: Absolutely! Lemon bars are a great make-ahead dessert. Store them in the refrigerator for up to 5 days.

Q: Why did my lemon bars crack on top?
A: Overbaking is the most common cause of cracked lemon bars. Be sure to remove them from the oven when the filling is set but still slightly jiggly.
