These bars come together quickly and bake into beautiful layers. Follow these easy steps for a flawless lemon dessert.

Step 1: Preheat and prepare

• Preheat your oven to 350°F (175°C).

• Line an 8×8 or 9×9-inch pan with parchment paper, leaving an overhang on the sides for lifting later.

Step 2: Make the crust and crumble

• In a bowl, combine flour, sugar, and salt.

• Pour in melted butter and vanilla extract. Mix until crumbly.

• Press 2/3 of the mixture firmly into the bottom of the prepared pan to form the crust.

Step 3: Bake the crust

• Bake the crust for 10–12 minutes, just until lightly golden.

• Remove from the oven and let it cool slightly.

Step 4: Make the lemon cream filling

• In a separate bowl, whisk together sweetened condensed milk, egg yolks, lemon juice, and zest until smooth and creamy.

Step 5: Assemble the bars

• Pour the lemon cream mixture over the cooled crust.

• Crumble the reserved dough evenly over the top of the filling.

Step 6: Bake again

• Return the pan to the oven and bake for 20–23 minutes, or until the topping is lightly golden and the filling is set.

Step 7: Cool and chill

• Let the bars cool completely at room temperature.

• Refrigerate for at least 2 hours before slicing for clean, firm squares.

9. Expert Tips for Perfect Lemon Bars

• Use fresh lemon juice – Bottled lemon juice doesn’t have the same flavor punch

• Zest before juicing – It’s easier and prevents waste

• Chill before cutting – This firms the filling and prevents mess

• Use a sharp knife – Clean the blade between slices for perfect squares

Bars stick to the pan

• Line with parchment and use the overhang to lift them out cleanly.

Filling is too tart

Bars are too sweet
