Prep & Cooking Time

Ingredients You Will Need

For the Buttery Shortbread Crust:

• 1 cup (2 sticks) Unsalted Butter: Melted and slightly cooled.
• 1/2 cup Granulated White Sugar: Adds delicate sweetness.
• 2 cups All-Purpose Flour: Spooned and leveled accurately.
• 1/2 tsp Pure Vanilla Extract: Enhances crust flavor.
• 1/4 tsp Kosher Salt: Balances the shortbread rich pastry notes.

For the Tangy Lemon Filling:

• 1.5 cups Granulated White Sugar: Sweetens the tart lemon base.
• 1/4 cup All-Purpose Flour: Thickens the lemon curd layer.
• 6 Large Eggs: Room temperature.
• 1 cup Freshly Squeezed Lemon Juice: From about 4 to 5 large lemons (avoid bottled juice!).
• 1 tbsp Fresh Lemon Zest: Provides rich citrus aroma.
• Powdered Sugar: For dusting before serving.

Step-by-Step Instructions

1. Preheat & Prepare Pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch metal baking pan with parchment paper, leaving an overhang on the sides for easy removal.
2. Make Shortbread Crust: In a medium bowl, combine melted butter, granulated sugar, vanilla extract, salt, and 2 cups of flour. Stir until a soft dough forms. Press the dough evenly into the bottom of your prepared baking pan.
3. Bake Crust: Bake the shortbread crust at 350°F (175°C) for 18 to 20 minutes until the edges are lightly golden brown.
4. Prepare Lemon Filling: While the crust bakes, whisk together granulated sugar and 1/4 cup flour in a large bowl. Add eggs, freshly squeezed lemon juice, and fresh lemon zest. Whisk thoroughly until smooth and completely combined.
5. Pour and Bake Filling: Pour the lemon filling directly over the hot, pre-baked shortbread crust. Reduce oven temperature to 325°F (165°C) and bake for 20 to 25 minutes until the center is set and doesn’t jiggle when gently shaken.
6. Cool, Chill, & Serve: Allow the pan to cool completely at room temperature for 1 hour, then refrigerate for at least 2 hours to fully set. Dust generously with powdered sugar, slice into squares, and enjoy!

Chef’s Note: Always use fresh lemon juice instead of bottled juice! Fresh lemons provide that bright, authentic citrus flavor that makes your lemon filling taste vibrant and refreshing.

Frequently Asked Questions

Why are my lemon bars runny?

Lemon bars remain runny if the filling wasn’t baked long enough to set the eggs, or if they weren’t allowed to cool and chill thoroughly in the fridge before slicing.

Can I reduce the sugar in the filling?

Reducing sugar will significantly increase the sour tartness of the lemons and may affect how firm the curd sets. It is best to stick to the recipe ratio for optimal texture.
