Instructions

Preheat & prepare the pan: Preheat the oven to 350°F (180°C). Line a 9×13-inch (23×33cm) glass or ceramic baking dish with parchment paper, leaving an overhang for easy lifting.
Make the crust: In a food processor, pulse the flour, powdered sugar, salt, and vanilla. Add the cold butter and pulse until the mixture resembles coarse crumbs. If the dough looks too dry to hold together, add 1–2 teaspoons milk just until it clumps when pressed.
Press & chill: Transfer the dough to the prepared pan and press it firmly and evenly into the bottom. Prick the surface all over with a fork. Chill in the refrigerator for 30 minutes.
Bake the crust: Bake for 18–24 minutes, or until golden around the edges. Do not remove from the oven.
Make the lemon filling: While the crust bakes, rub the sugar and lemon zest together in a bowl to release the oils. Add flour and whisk. Add the eggs, whisking until smooth, then add lemon juice. For an ultra-smooth filling, strain through a fine-mesh sieve.
Bake the bars: Immediately (and carefully) pull the rack out slightly and pour the filling directly onto the crust while it’s still in the oven. Bake for 20–25 minutes, or until the center is just set and no longer jiggles. (Important: don't let the crust cool, pour in curd immediately.)
Cool & chill: Let the bars cool completely at room temperature, then refrigerate for at least 1 hour before slicing.
Serve: Dust generously with powdered sugar. Slice into squares and enjoy!

Notes

Milk: You may not need it. Only add 1–2 teaspoons if the dough feels powdery and doesn't hold together when pressed. The dough should feel soft, slightly sandy, and cohesive.
Chill the crust: Don’t skip this step. A warm crust shrinks in the oven, causing gaps around the edges and uneven bars.
Pan Choice Matters: Use glass or ceramic. Metal pans can sometimes cause a slightly metallic aftertaste with acidic fillings like lemon. If using metal, line thoroughly with parchment.
Prevent Crust Shrinkage: After baking, do not remove the crust from the oven. Sudden temperature changes can cause it to contract. Instead, open the oven door and pour the filling directly over the hot crust.
Filling Texture: For a silky, zest-free filling, strain the mixture through a fine-mesh sieve before baking
For a richer curd: Use 4 whole eggs + 3 egg yolks instead of 6 whole eggs.
Sweetness Level: If you prefer a tarter bar, reduce sugar in the filling to 1 cup (200g).
Lemon Juice: Always use fresh lemon juice. Bottled lemon juice can make the filling overly sharp or bitter.
Storage: Store lemon bars in an airtight container in the fridge for up to 5 days. They also freeze beautifully, freeze sliced bars (without powdered sugar) for up to 3 months, then thaw and dust before serving.
