Ingredients

For the Shortbread Crust:

2 cups all-purpose flour
½ cup granulated sugar
¼ teaspoon salt
1 cup unsalted butter, melted

For the Lemon Filling:
1½ cups granulated sugar
¼ cup all-purpose flour
4 large eggs
⅔ cup freshly squeezed lemon juice
1 tablespoon lemon zest

For Garnish:
Powdered sugar for dusting
Thin lemon slices (optional)
Fresh mint leaves (optional)

Steps To Create Recipe

1. PREPARE THE OVEN
Preheat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.

2. MAKE THE SHORTBREAD CRUST
In a bowl, combine the flour, sugar, salt, and melted butter until a soft dough forms. Press the mixture evenly into the prepared pan. Bake for 18–20 minutes, or until lightly golden.

3. PREPARE THE LEMON FILLING
While the crust bakes, whisk together the sugar and flour. Add the eggs, lemon juice, and lemon zest, whisking until smooth.

4. BAKE THE BARS
Pour the filling over the warm crust. Return the pan to the oven and bake for 20–25 minutes, or until the center is set and no longer jiggles.

5. COOL COMPLETELY
Let the bars cool to room temperature, then refrigerate for at least 2 hours for clean slicing.

6. SLICE AND GARNISH
Lift the bars from the pan using the parchment paper. Dust generously with powdered sugar and cut into squares.

Common Mistakes to Avoid

Bottled Lemon Juice
Using bottled lemon juice instead of fresh juice.

Overbaking
Overbaking, which can make the filling rubbery.

Cutting Too Soon
Cutting before the bars have chilled completely.

Forgetting Parchment
Forgetting to line the pan with parchment paper.

Overmixing Filling
Overmixing the filling and incorporating excess air.

Powdered Sugar Too Early
Adding powdered sugar too early, causing it to dissolve before serving.

Frequently Asked Questions

Q: Can I use bottled lemon juice?
A: Fresh lemon juice is strongly recommended for the best flavor and aroma.

Q: Why are my lemon bars runny?
A: They may have been underbaked or not chilled long enough before slicing.

Q: Can I make them ahead of time?
A: Yes. Lemon bars are an excellent make-ahead dessert and often taste even better the next day.

Q: How do I get clean slices?
A: Chill thoroughly and wipe the knife clean between cuts.

Q: Can I add extra lemon zest?
A: Absolutely. More zest intensifies the citrus flavor without adding extra liquid.

Q: Should powdered sugar be added before storing?
A: It's best to dust with powdered sugar just before serving, as moisture can cause it to dissolve.
