Detailed Directions and Instructions
Step 1: Preheat the Oven
Preheat the oven to 350°F.
Step 2: Prepare the Pan
Spray a 9 x 13-inch pan with cake release and double-line it with parchment paper, ensuring that the paper is 1 inch higher than the pan.
Step 3: Mix the Crust Ingredients
In a mixing bowl, combine the softened butter, granulated sugar, all-purpose flour, and grated lemon rind. Using the paddle attachment on slow speed, mix until the mixture resembles breadcrumbs and begins to form into a ball.
Step 4: Press the Crust Mixture
Transfer the mixture into the prepared pan and press it down evenly with your fingers.
Step 5: Smooth the Crust
Place a 9 x 13-inch rectangle of baking paper on top of the crust and apply firm pressure with a cake smoother to flatten and smooth the base.
Step 6: Prick the Crust
Remove the top paper and prick the crust all over with a fork.
Step 7: Bake the Crust
Bake the crust for 18-20 minutes, or until it is golden.
Step 8: Prepare the Topping Mixture
While the crust is baking, clean the mixing bowl and whisk together the superfine sugar and flour for the topping.
Step 9: Combine Topping Ingredients
Add the eggs, egg yolks, and freshly squeezed lemon juice to the sugar-flour mixture. Mix until combined using a whisk or hand blender, keeping the blade under the mixture to avoid incorporating air.
Step 10: Adjust Oven Temperature
Once the crust is baked, remove it from the oven and reduce the temperature to 320°F.
Step 11: Strain Lemon Mixture
Strain the lemon mixture into a jar and pour it over the baked crust.
Step 12: Bake the Topping
Bake for 20-25 minutes until set. The topping is ready when it does not wobble upon shaking the pan.
Step 13: Cool the Bars
Remove from the oven and allow to cool on a cooling rack for about an hour before transferring to the refrigerator. Refrigerate for at least 3 hours.
Step 14: Lift the Bars
When ready to serve, gently lift the bars from the pan using the parchment paper.
Step 15: Cut the Bars
Transfer the bars to a cutting board, trim the edges with a sharp, hot knife (wiping it clean after each cut), and cut into 24 bars.
Step 16: Dust with Powdered Sugar
Dust the tops of the bars with powdered sugar before serving.
Notes
Note 1: Cooling Before Refrigerating
Allow the bars to cool completely at room temperature before refrigerating to prevent cracks in the filling.
Note 2: Storage Instructions
Store the lemon bars in an airtight container in the refrigerator for up to 3 days.
Note 3: Freezing Method
To freeze, place the cut bars in an airtight container, separating layers with parchment paper. They can be frozen for up to 2 months.

Cook techniques
Mixing Ingredients
Incorporate softened butter and sugar until the mixture resembles breadcrumbs. Use a paddle attachment at slow speed to achieve the right texture.
Pressing the Crust
Transfer the crust mixture to the prepared pan and press it down evenly with your fingers for a uniform base. Use a cake smoother with baking paper on top to flatten.
Pricking the Crust

FAQ
Can I use salted butter instead of unsalted for the crust?
