1-Preparation: First, gather all your ingredients and equipment. For this easy lemon bars recipe, you’ll need a 9×13-inch baking dish, parchment paper, mixing bowls, a whisk, and a food processor (if available).

2-Creating the Buttery Crust: 1. Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper, ensuring it hangs over the sides for easy removal later. 2. In a medium bowl, whisk together 2 ½ cups flour, ⅔ cup powdered sugar, and ½ tsp salt until well combined. 3. Add 12 tbsp melted unsalted butter to the dry ingredients. Mix until just combined. For an extra flavor boost, you can add a dash of vanilla extract at this stage. 4. Press the dough evenly into the bottom of your prepared pan. The mixture should be about ¼ inch thick. You want to make sure it’s compact and even to prevent holes in your crust. 5. Bake for 20 minutes until golden. The edges should be lightly browned while the center remains pale. This ensures a crisp but tender crust that can support the filling.

3-Preparing the Tangy Filling: 1. While the crust is baking, prepare the filling. In a food processor, pulse 3 cups sugar and 3 tbsp lemon zest until well blended. This step helps release the oils from the zest, intensifying the citrus flavor. 2. In a large bowl, combine the sugar-zest mixture with the remaining ½ cup flour. 3. Whisk in 1 cup fresh lemon juice and 8 large eggs (at room temperature) until smooth. If your eggs are cold, you can warm them by placing them in a bowl of warm water for a few minutes before use.

4-Assembling and Baking: 1. Once the crust is golden, remove it from the oven and immediately pour the filling over the warm crust. Pour slowly to avoid disturbing the crust. 2. Return the pan to the oven and bake for 25 minutes, rotating the pan halfway through baking. The bars are done when the center is set with no jiggle when you gently shake the pan. 3. Remove from the oven and let cool at room temperature for 1 hour. Then transfer to the refrigerator and chill for at least 2 hours. This cooling process is essential for the filling to set properly. 4. Once completely chilled, dust with powdered sugar and cut into squares. For clean cuts, use a sharp knife dampened with warm water between each slice.
