Ingredients

Crust
— 1 ¾ cups (220 g) all-purpose flour
— ⅓ cup (65 g) granulated sugar
— ¼ teaspoon salt
— ¾ cup (170 g) unsalted butter, cold and diced

Filling
— 1 cup (200 g) granulated sugar
— 3 large eggs, room temperature
— ⅔ cup (160 ml) freshly squeezed lemon juice (about 3–4 lemons)
— Zest of 2 lemons
— ½ cup (60 g) all-purpose flour
— ½ teaspoon baking powder
— A pinch of salt

How to make it

1. Preheat and prep
Preheat oven to 350°F (175°C). Line a 9×9-inch (23×23 cm) baking pan with parchment paper, leaving an overhang for easy removal.

2. Make the crust
In a bowl, mix flour, sugar, and salt. Add cold butter pieces. Use a pastry cutter or your fingers to blend until mixture looks like coarse crumbs.

3. Bake the crust
Press crumbs firmly into the pan in an even layer. Bake for 15–18 minutes, until edges turn light golden. Remove from oven but keep the oven on.

4. Prepare the filling
Whisk sugar and eggs in a medium bowl until smooth. Stir in lemon juice, zest, flour, baking powder, and salt. Mix until well combined.

5. Bake the bars
Pour filling over the hot crust. Return pan to oven and bake 15–18 minutes more, until filling is set but still slightly jiggly in the center.

6. Cool and cut
Let pan cool on a wire rack for 1 hour. Then refrigerate for at least 2 hours. Use the parchment overhang to lift the bars out. Cut into 16 squares with a sharp knife.

Tips and common mistakes

— Don’t skip chilling after baking; it helps the bars set.
— Use fresh lemons for best flavor. Bottled juice can taste flat.
— Press crust firmly to avoid cracks in the filling.
— If filling browns too fast, cover loosely with foil.

Substitutions

— Gluten-free: Replace all-purpose flour with a 1:1 gluten-free blend.
— Vegan: Use a vegan butter substitute and “flax eggs” (3 tbsp ground flax + 6 tbsp water).
— Sugar-free: Swap granulated sugar for an equal amount of erythritol or monk fruit sweetener.

Storage instructions

Store lemon bars in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze bars in a single layer on a baking sheet, then transfer to a freezer bag for up to 2 months. Thaw in the fridge before serving.

FAQ

Q: Can I use bottled lemon juice?
A: Fresh juice gives the best taste. Bottled juice works but may be less vibrant.

Q: Why is my filling runny?
A: Underbaking or skipping the chill step can cause a soft filling. Bake until set, then chill well.

Q: How do I get clean cuts?
A: Cool fully, chill in the fridge, and wipe your knife between cuts.

Q: Can I double this recipe?
A: Yes. Use a 9×13-inch pan and extend baking times by 5–10 minutes.
