Foolproof Lemon Bars
HB-7016 · Hand-built original
Lemon bars with a sandy, pressed shortbread crust of flour, powdered sugar, butter and egg yolk, baked golden and covered while still warm with a tangy lemon, egg and milk filling, then chilled and cut into squares.
Main ingredient: egg
Pairs well with: toast, hash browns, fruit salad, bacon, avocado
Ingredients
- 1¼ cups plus 3 Tbsp. (6¼ oz) all-purpose flour
- ¼ cup powdered sugar, plus more for dusting
- 1¼ tsp Diamond Crystal or ¾ tsp. Morton kosher salt, divided
- 7 Tbsp. chilled unsalted butter, cut into pieces
- 2 large egg yolks, divided
- 1 cup granulated sugar
- 2 tsp. finely grated lemon zest
- 3 large eggs
- ⅔ cup fresh lemon juice
- ¼ cup whole milk
Method
- Set a rack in the middle of the oven and heat it to 325°F, then line an 8x8-inch baking pan with parchment paper, leaving overhang on all sides.
- Pulse 1 1/4 cups of the flour with the powdered sugar and 3/4 teaspoon of Diamond Crystal salt in a food processor to combine, add the chilled butter pieces and pulse until the mixture is sandy with very small pieces of butter, then add 1 of the egg yolks and pulse until the mixture holds together when squeezed, though it will look dry and powdery.
- Tip the crust mixture into the prepared pan, spread it into an even layer and pack it down firmly with a flat-bottomed measuring cup or glass, using your fingers to press it into the corners.
- Bake the crust for 27 to 29 minutes until golden, then let it cool for exactly 5 minutes — it needs to still be warm when the filling goes on.
- While the crust bakes, rub the granulated sugar and lemon zest together in a medium bowl with your fingers for about 1 minute, until the sugar is fragrant and lightly tinted yellow.
- Gently whisk the eggs, the remaining egg yolk and the remaining 3 tablespoons of flour into the lemon sugar just until combined, then stir in the lemon juice, whole milk and the remaining salt.
- Pour the lemon mixture over the warm crust, tap the pan on the counter to pop any air bubbles on the surface and return the pan to the oven quickly.
- Bake for 20 to 25 minutes, until the lemon filling is set but still jiggles slightly when the pan is gently shaken.
- Let the lemon bar cool completely, then chill it until cold, at least 4 hours.
- Lift the slab out of the pan by its parchment overhang, cut it into 16 squares and dust the bars with powdered sugar just before serving.
