Ingredients You’ll Need
- For the crust: 2 cups all-purpose flour, ½ cup powdered sugar, ¼ teaspoon salt, and 1 cup (2 sticks) cold unsalted butter, cubed
- For the filling: 4 large eggs, 1½ cups granulated sugar, ¼ cup all-purpose flour, ⅔ cup fresh lemon juice (from about 4 lemons), and 1 tablespoon lemon zest
- Powdered sugar, for dusting
How to Make Lemon Bars with Shortbread Crust
- Preheat the oven to 350°F (175°C) and line a 9×13-inch pan with parchment paper, leaving an overhang for lifting.
- Pulse the flour, powdered sugar, and salt in a food processor, add the cold butter, and pulse until crumbly. Press the dough firmly into the bottom of the pan.
- Bake the crust for 18 to 20 minutes until lightly golden.
- Whisk the eggs, granulated sugar, flour, lemon juice, and lemon zest until smooth.
- Pour the filling over the hot crust and return to the oven for 20 to 25 minutes until the filling is set and no longer jiggles in the center.
- Cool completely at room temperature, then chill for 1 hour before lifting out, cutting into 24 bars, and dusting with powdered sugar.
Tips for the Best Tangy Lemon Bars
- Use fresh lemon juice; bottled juice tastes flat.
- Press the crust firmly so it holds together when cut.
- Pour the filling over the warm crust for a better bond.
- Do not overbake or the filling can crack.
- Chill before cutting and wipe the knife between slices.
Variations to Try: Lemon Bar Ideas
- Add a few tablespoons of lime or orange juice for a citrus twist.
- Stir fresh blueberries into the filling.
- Add lemon zest to the crust for extra lemon flavor.
- Top with a thin lemon glaze instead of powdered sugar.
How to Store It
Refrigerate the bars in an airtight container for up to 5 days; dust with powdered sugar just before serving because it absorbs into the filling. Freeze for up to 2 months in a single layer and thaw in the fridge.
