Ingredients and Preparation

Crust

• 1 cup unsalted butter, at room temperature
• 2 cups all-purpose flour
• ½ cup powdered sugar
• ½ teaspoon salt

Lemon Layer

• 4 eggs
• 5-6 tablespoons lemon juice (freshly squeezed for best flavor)
• 1¾ cups granulated sugar
• ⅓ cup all-purpose flour
• Powdered sugar for topping

Ingredient Substitutions and Variations

• Butter Alternative: If you prefer, you can use plant-based butter for a dairy-free version.
• Flour Options: While all-purpose flour works best, a 1:1 gluten-free flour substitute can be used.
• Lemon Juice: Fresh lemon juice is recommended for its bright, fresh flavor, but bottled lemon juice will work in a pinch.
• Sugar: If you want a slightly healthier option, coconut sugar can replace granulated sugar, though it will alter the color and flavor slightly.
• Additional Flavors: A teaspoon of vanilla extract or a pinch of zest from the lemon peel can enhance the citrus notes in the filling.

Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C). Grease a 9×13-inch glass baking dish with butter or cooking spray and set it aside. Using a glass dish ensures even baking and prevents the bars from becoming too crisp on the edges.

Step 2: Make the Crust

In a medium-sized mixing bowl, combine the butter, flour, powdered sugar, and salt. Use a pastry cutter or a spatula to mix the ingredients until they form a crumbly, dough-like texture. If you don’t have a pastry cutter, a fork or your hands will work just as well.

Press the mixture evenly into the prepared baking dish, making sure it covers the bottom completely. Try to create an even layer so the crust bakes uniformly.

Step 3: Bake the Crust

Place the baking dish in the preheated oven and bake for 20 minutes. The crust should be set but not browned. Overbaking at this stage can cause the crust to become too crisp, so watch it carefully.

Step 4: Prepare the Lemon Filling

While the crust is baking, prepare the lemon layer. In a medium-sized bowl, beat the eggs, lemon juice, granulated sugar, and flour together using a hand mixer or whisk. Mix until the ingredients are well combined and slightly frothy. This aeration helps create a light and smooth texture in the filling.

Step 5: Assemble and Bake

Once the crust has finished baking, remove it from the oven and immediately pour the lemon mixture over the warm crust. This helps the filling adhere properly and prevents separation between layers.

Return the dish to the oven and bake for an additional 22-24 minutes. The lemon bars are done when the edges are slightly golden and the center is set. If you gently shake the pan, the filling should not wobble. Overbaking can cause the bars to become rubbery, so check frequently as the baking time nears completion.

Step 6: Cool and Serve

Allow the lemon bars to cool completely in the pan. This step is crucial for setting the filling. Once cooled, sift powdered sugar over the top for a classic finishing touch. Use a sharp knife to cut them into squares or rectangles. For cleaner slices, wipe the knife with a damp cloth between cuts.

Beginner Tips and Notes

Common Mistakes and How to Avoid Them

• Overbaking the Crust: The crust should be set but not browned before adding the filling. If it’s too brown, it may become overly crunchy.
• Lumpy Filling: Always whisk the filling thoroughly to avoid lumps. If needed, strain the mixture through a fine-mesh sieve before pouring it over the crust.
• Soggy Bars: Make sure the lemon bars cool completely before cutting to prevent them from becoming too soft. Chilling them in the refrigerator can help firm them up.
• Too Tart or Too Sweet: The amount of lemon juice can be adjusted to taste. If you prefer a more tart flavor, use 6 tablespoons of lemon juice. For a milder taste, use 5 tablespoons.

Helpful Kitchen Tips

• Prepping Efficiently: Measure and prepare all ingredients before you begin. This will make the process smoother and prevent mistakes.
• Cutting Clean Slices: To get neat, professional-looking lemon bars, chill them in the refrigerator for an hour before slicing.
• Enhancing Flavor: A pinch of salt in the lemon filling can bring out the citrus notes and balance the sweetness.

Serving Suggestions

Lemon bars are delicious on their own, but they can be elevated with simple additions:

• Paired with Fresh Fruit: Serve with fresh berries like strawberries, raspberries, or blueberries for a colorful contrast.
• With Whipped Cream: A dollop of whipped cream adds a rich, creamy texture that balances the tartness of the lemon.
• Drizzled with White Chocolate: Melted white chocolate drizzled over the bars creates an extra layer of sweetness.
• Alongside Tea or Coffee: Lemon bars pair beautifully with black tea, green tea, or a cup of freshly brewed coffee.

Storage Tips for Leftovers

Lemon bars store well and can be enjoyed for several days if kept properly.

• Room Temperature: If you plan to eat them within a day, keep them in an airtight container at room temperature.
• Refrigeration: For longer storage, keep them in an airtight container in the refrigerator for up to a week.
• Freezing: Lemon bars can be frozen for up to three months. Wrap individual bars in plastic wrap, then place them in a freezer-safe bag. Thaw them in the refrigerator overnight before serving.
