Recipe Details

Prep Time: 20 minutes
Cook Time: 40 minutes
Total Time: 1 hour 10 minutes (plus cooling time)
Servings: 16 bars

Ingredients

• 1 3/4 cups all-purpose flour
• 2/3 cup powdered sugar (plus extra for dusting)
• 3/4 cup unsalted butter, cold and cubed
• 4 large eggs
• 1 1/2 cups granulated sugar
• 1/4 cup all-purpose flour
• 1/4 cup fresh lemon juice (about 2 lemons)
• 1 teaspoon lemon zest

Instructions

1. 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.
2. Prepare the crust by combining 1 3/4 cups flour and 2/3 cup powdered sugar in a large bowl. Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
3. Press the crust mixture firmly into the prepared pan, creating an even layer. Bake for 15 minutes until lightly golden around the edges.
4. While the crust bakes, prepare the filling. In a medium bowl, beat the eggs with granulated sugar until well combined and slightly frothy.
5. Add 1/4 cup flour, lemon juice, and lemon zest to the egg mixture. Whisk until smooth and completely incorporated.
6. Remove the partially baked crust from the oven and pour the lemon filling over the hot crust, spreading it evenly.
7. Return to the oven and bake for an additional 20-25 minutes, or until the filling is set and no longer jiggles in the center.
8. Allow the lemon bars to cool completely in the pan on a wire rack, about 1-2 hours. For best results, refrigerate for at least 2 hours before cutting.
9. Once chilled, lift the bars out using the parchment overhang. Dust generously with powdered sugar and cut into 16 squares.

Pro Tips for Perfect Lemon Bars

• Use room temperature eggs for the filling to ensure they incorporate smoothly without lumps.
• Don’t overbake the filling – it should still have a slight jiggle in the center when you remove it from the oven. It will continue to set as it cools.
• Chill the bars thoroughly before cutting for clean, sharp edges. A warm knife run under hot water helps make perfect cuts.
• Fresh lemon juice makes all the difference – avoid bottled juice for the brightest, most authentic flavor.
• Add a pinch of salt to the crust mixture to enhance the buttery flavor and balance the sweetness.

Variations and Substitutions

For a healthier twist, you can substitute half the all-purpose flour in the crust with whole wheat pastry flour. You can also reduce the sugar in the filling by 1/4 cup if you prefer a more tart lemon bar. For a gluten-free version, use a 1:1 gluten-free flour blend in both the crust and filling. To add extra dimension, try incorporating 1 tablespoon of finely chopped fresh mint or basil into the filling, or add 1/2 cup of fresh blueberries to the lemon mixture before baking for beautiful color contrast and flavor.

Storage and Reheating Tips

Lemon bars store beautifully in the refrigerator for up to 5 days when kept in an airtight container. Place parchment paper between layers to prevent sticking. For longer storage, freeze the bars (without the powdered sugar topping) for up to 3 months. Wrap individual bars in plastic wrap, then place in a freezer-safe container. Thaw overnight in the refrigerator and dust with fresh powdered sugar before serving. These bars are best served chilled or at room temperature – avoid heating as it can cause the filling to become runny.

Frequently Asked Questions

• Why did my lemon bars have a soggy bottom? This usually happens when the crust isn’t baked long enough before adding the filling. Make sure to bake the crust until it’s lightly golden and feels set to the touch.
• Can I make lemon bars ahead of time? Absolutely! These actually taste better when made a day ahead, as it gives the flavors time to develop. Store them in the refrigerator and add the powdered sugar just before serving.
• How do I know when the lemon bars are done? The filling should be set around the edges but still have a slight jiggle in the very center. It will continue to set as it cools.
• Can I use Meyer lemons instead of regular lemons? Yes! Meyer lemons will give you a slightly sweeter, more floral flavor. You might want to reduce the sugar by a couple of tablespoons since Meyer lemons are naturally sweeter.
• Why did my filling separate or curdle? This can happen if the eggs were too cold when mixed or if the bars were baked at too high a temperature. Always use room temperature eggs and bake at the recommended temperature.
