Chef’s Pro Tips for Perfect Results

• Cold Butter: Use cold butter for the crust—it makes the shortbread tender and flaky.
• Fresh Lemons: Freshly squeezed lemon juice and zest give the best flavor. Bottled juice will work but may taste slightly different.
• Don’t Overbake: The filling should be just set; it will firm up as it cools. Overbaking can make it dry or rubbery.
• Line Your Pan: Parchment paper with overhang makes lifting the bars out and slicing much easier.
• Chill Before Slicing: Gives clean, neat slices and helps the filling set properly.

Ingredients in Lemon Bars

Here’s what makes these bars bright, buttery, and irresistible:

Granulated Sugar: Provides sweetness in both the crust and filling. Dividing it ensures the crust stays crisp while the filling is perfectly sweet.

Salted Butter: Cold, cubed butter creates a tender shortbread base that’s buttery and rich.

Vanilla Extract: Adds a warm depth to the buttery crust.

All-Purpose Flour: Forms the structure of the shortbread crust.

Eggs: Bind the lemon filling and create a smooth, custard-like texture.

Lemon Juice & Zest: The stars of the show—bright, tangy, and full of fresh citrus flavor.

Powdered Sugar: Optional topping that adds a delicate sweetness and makes the bars look as pretty as they taste.

Instructions

Here’s how to make lemon bars that impress every time:

Preheat Oven: Preheat oven to 350°F (175°C). Line a 9×13-inch pan with parchment paper.

Make the Crust: In a mixing bowl, combine cold cubed butter, 1 1/2 cups granulated sugar, vanilla extract, and 2 cups flour. Mix until a crumbly dough forms. Press evenly into the prepared pan.

Bake Crust: Bake for 15–20 minutes until the edges are lightly golden. Remove from oven and let cool slightly.

Prepare Lemon Filling: In a large bowl, whisk together eggs, remaining 1 1/2 cups sugar, lemon juice, and lemon zest until smooth.

Pour Over Crust: Pour lemon mixture evenly over the baked crust.

Bake Again: Bake for 20–25 minutes, or until filling is set but slightly jiggly in the center. Remove from oven and let cool to room temperature.

Chill: Refrigerate for at least 2 hours before slicing for clean bars.

Optional Topping: Sprinkle with powdered sugar and extra lemon zest for a pretty, flavorful finish.

Slice & Serve: Lift bars from pan using parchment overhang and cut into squares or rectangles.
