• Baking: 35 minutes
• Total: 55 minutes

Yield

12 generous squares

Difficulty Level

Easy – perfect for bakers of all skill levels

Ingredients

• For the Buttery Shortbread Base:
  • 1 cup unsalted butter, softened to room temperature
  • ½ cup granulated sugar
  • 2 cups all-purpose flour, sifted
  • ¼ teaspoon salt
• For the Lemon Filling:
  • 1 ½ cups granulated sugar
  • 3 tablespoons all-purpose flour
  • 4 large eggs, at room temperature
  • 2/3 cup freshly squeezed lemon juice (about 3-4 lemons)
  • 1 tablespoon finely grated lemon zest
  • ½ teaspoon baking powder
• For dusting: Powdered sugar

Instructions

1. Prepare the Shortbread Base: Preheat the oven to 350°F (175°C). Using a stand mixer or hand mixer, cream the softened butter and granulated sugar until light and fluffy, about 3 minutes. Gradually add the sifted flour and salt, mixing just until combined to avoid overworking the dough. Press the dough evenly into a 9×13-inch baking pan lined with parchment paper, ensuring a smooth, compact surface.
2. Bake the crust: Place the pan in the oven and bake for 18-20 minutes or until the edges turn a subtle golden hue. Remove and allow it to cool slightly while preparing the filling.
3. Mix the Lemon Filling: In a medium bowl, whisk together the granulated sugar, flour, and baking powder. Add the eggs, one at a time, mixing until fully incorporated and smooth. Stir in the fresh lemon juice and zest, blending until the filling is bright and silky.
4. Assemble and Bake: Carefully pour the lemon filling over the partially cooled shortbread base, spreading evenly with a spatula.Return to the oven and bake for 18-22 minutes, or until the filling is set but still slightly jiggly in the center-this ensures a creamy texture.
5. Cool Fully: Remove from oven and cool to room temperature on a wire rack. For best results,refrigerate for at least 2 hours to allow the filling to firm and flavors to meld.
6. Slice and Serve: Dust with powdered sugar just before slicing into bars. Use a sharp knife dipped in hot water and wiped dry between cuts for clean edges.

Tips for Success

• Use cold butter for the crust if you prefer a more crumbly texture. For a richer base,room temperature butter creates a tender,buttery bite.
• Freshly squeezed lemon juice is essential for vibrant tartness; bottled lemon juice often lacks the bright, natural flavor.
• Don’t skip the lemon zest-it enhances aroma and intensifies the citrus profile.
• Allow the filling to set fully in the refrigerator; this makes cutting easier and the bars hold together better.
• For gluten-free variation, substitute all-purpose flour with a 1:1 gluten-free baking blend and increase baking time by 2-3 minutes.
• If the lemon filling cracks slightly when baking, don’t worry-this signals a perfectly baked custard texture.

Serving Suggestions

Present these zesty lemon bars on a rustic wooden tray or a bright ceramic platter to enhance their sunny appeal. Garnish each square with a thin twist of lemon peel or a fresh mint leaf for a pop of color and elegance. For an extra layer of indulgence, drizzle a light vanilla glaze or serve with a dollop of whipped cream. These bars pair wonderfully with a cup of chamomile tea or a sparkling lemonade for a cohesive citrus-themed experience.

Q6: Can the recipe be adapted for dietary preferences or restrictions?
