Lemon Cake Bars: Prepare to be transported to a sun-drenched citrus grove with every single bite! These aren’t just any dessert; they’re a burst of sunshine on a cloudy day, a sweet and tangy symphony that will leave you craving more. I’m thrilled to share this recipe with you, a delightful twist on the classic lemon bar that’s incredibly easy to make and even easier to devour.

The allure of lemon desserts stretches back centuries, with lemons themselves being prized for their medicinal and culinary properties. While the exact origins of the lemon bar are debated, its popularity soared in the mid-20th century, becoming a staple at bake sales and family gatherings. What makes these lemon cake bars so irresistible? It’s the perfect balance of flavors and textures. The buttery, crumbly base provides a comforting foundation for the vibrant, tangy lemon filling. The smooth, creamy filling contrasts beautifully with the slightly crisp edges, creating a truly satisfying experience.

Beyond the exquisite taste, these bars are incredibly convenient. They require minimal ingredients, come together quickly, and are perfect for potlucks, picnics, or simply a sweet treat to brighten your afternoon. So, gather your ingredients, preheat your oven, and let’s embark on a baking adventure that will fill your kitchen with the intoxicating aroma of fresh lemons!

Ingredients:

• For the Crust:
• 1 1/2 cups (180g) all-purpose flour
• 1/2 cup (100g) granulated sugar
• 1/2 teaspoon salt
• 1/2 cup (113g) cold unsalted butter, cut into cubes
• 1 large egg yolk
• 2 tablespoons ice water
• For the Lemon Filling:
• 4 large eggs
• 1 1/2 cups (300g) granulated sugar
• 1/4 cup (30g) all-purpose flour
• 1/4 teaspoon salt
• 1 cup (240ml) freshly squeezed lemon juice (from about 5-6 lemons)
• 2 tablespoons lemon zest (from about 3-4 lemons)
• 1/4 cup (57g) unsalted butter, melted
• For the Powdered Sugar Topping (optional):
• 1/4 cup powdered sugar

Preparing the Crust:

1. Combine Dry Ingredients: In a large bowl, whisk together the flour, sugar, and salt. This ensures the salt is evenly distributed, which is crucial for flavor.
2. Cut in the Butter: Add the cold, cubed butter to the flour mixture. Using a pastry blender or your fingertips, cut the butter into the flour until the mixture resembles coarse crumbs. The smaller the butter pieces, the flakier the crust will be. If using your fingertips, work quickly to prevent the butter from melting.
3. Add Egg Yolk and Water: In a small bowl, whisk together the egg yolk and ice water. Pour this mixture over the flour and butter mixture.
4. Mix the Dough: Using a fork or your hands, gently mix the ingredients until a dough starts to come together. Be careful not to overmix, as this can develop the gluten in the flour and result in a tough crust. The dough should be slightly crumbly but hold together when pressed.
5. Press into Pan: Press the dough evenly into the bottom of an ungreased 9×13 inch baking pan. I like to use the bottom of a measuring cup to ensure it’s packed down firmly and evenly. This helps prevent the crust from shrinking during baking.
6. Pre-bake the Crust: Preheat your oven to 350°F (175°C). Bake the crust for 18-20 minutes, or until it’s lightly golden brown. This pre-baking step is essential to prevent a soggy crust. Let the crust cool slightly while you prepare the lemon filling.

Making the Lemon Filling:

1. Whisk Eggs and Sugar: In a large bowl, whisk together the eggs and sugar until light and slightly thickened. This usually takes about 2-3 minutes.
2. Add Dry Ingredients: Whisk in the flour and salt until well combined. Make sure there are no lumps of flour remaining.
3. Incorporate Lemon Juice and Zest: Gradually whisk in the lemon juice and lemon zest. The mixture will become quite liquid at this point, which is perfectly normal. The lemon juice is what gives these bars their signature tangy flavor.
4. Add Melted Butter: Slowly drizzle in the melted butter while whisking constantly. This helps to emulsify the butter into the mixture and create a smooth, creamy filling.

Baking the Lemon Bars:

1. Pour Filling over Crust: Pour the lemon filling evenly over the pre-baked crust.
2. Bake: Bake in the preheated oven for 25-30 minutes, or until the filling is set but still slightly jiggly in the center. The edges should be lightly golden brown. Be careful not to overbake, as this can result in a dry or cracked filling.
3. Cool Completely: Remove the lemon bars from the oven and let them cool completely in the pan on a wire rack. This is crucial for the filling to set properly. I know it’s tempting to cut into them while they’re still warm, but trust me, they’re much better when fully cooled.

Cutting and Serving:

1. Chill (Optional): For even cleaner cuts, you can chill the lemon bars in the refrigerator for at least 30 minutes before cutting. This helps the filling to firm up even more.
2. Cut into Bars: Using a sharp knife, cut the lemon bars into squares or rectangles. Wipe the knife clean between each cut for the neatest results.
3. Dust with Powdered Sugar (Optional): If desired, dust the lemon bars with powdered sugar before serving. This adds a touch of sweetness and makes them look extra pretty.
4. Serve and Enjoy: Serve the lemon bars chilled or at room temperature. They’re delicious on their own or with a scoop of vanilla ice cream.

Tips for Success:

• Use Fresh Lemon Juice: Bottled lemon juice just doesn’t compare to the flavor of freshly squeezed lemon juice. It’s worth the extra effort to squeeze your own.
• Don’t Overbake: Overbaking will result in a dry, cracked filling. The filling should be set but still slightly jiggly in the center when you remove it from the oven.
• Cool Completely: This is the most important step! The filling needs time to set properly. Be patient and let the bars cool completely before cutting.
• Lemon Zest is Key: Don’t skip the lemon zest! It adds a ton of lemon flavor and aroma to the bars.
• Adjust Sweetness to Taste: If you prefer a less tart lemon bar, you can increase the amount of sugar in the filling by a tablespoon or two.
• Storage: Store leftover lemon bars in an airtight container in the refrigerator for up to 3 days.

Variations:

• Lime Bars: Substitute lime juice and zest for the lemon juice and zest for a tangy lime version.
• Orange Bars: Use orange juice and zest instead of lemon for a citrusy orange treat.
• Coconut Crust: Add 1/2 cup of shredded coconut to the crust for a tropical twist.
• Berry Topping: Top the baked lemon bars with fresh berries before dusting with powdered sugar.

Troubleshooting:

• Soggy Crust: Make sure to pre-bake the crust and let it cool slightly before adding the filling. Also, ensure the crust is packed down firmly and evenly in the pan.
• Cracked Filling: Avoid overbaking the bars. The filling should be set but still slightly jiggly in the center when you remove it from the oven.
• Filling Not Setting: Ensure you’re using the correct amount of flour in the filling. Also, make sure the bars are cooled completely before cutting.
• Too Tart: Adjust the amount of sugar in the filling to your liking. You can add a tablespoon or two more sugar to reduce the tartness.

For a more sophisticated presentation, try dusting them with powdered sugar or drizzling them with a white chocolate ganache. And if you’re feeling adventurous, there are plenty of variations you can try to customize these bars to your liking. For a more intense lemon flavor, add a teaspoon of lemon extract to the batter. You could also incorporate other citrus fruits, such as orange or lime, for a unique twist. If you’re a fan of nuts, try adding chopped pecans or walnuts to the batter for a bit of crunch.
