Luscious Lemon Bars

20 servings


1 hour 20 minutes

total time


  • 1¾ cup (220g) all-purpose flour, spooned into measuring cup and leveled-off

  • ¼ cup (30g) cornstarch

  • 1 teaspoon salt

  • 1 cup (100g) Confectioners' sugar, plus more to decorate finished bars

  • 2 sticks (1 cup)(240g) cold unsalted butter, cut into ½-inch pieces

  • 6 large eggs

  • 3 cups (600g) granulated sugar

  • 2 tablespoons lemon zest (be sure to zest the lemons before juicing)

  • ⅔ cup freshly squeezed lemon juice, from 5 to 6 lemons

  • ⅔ cup (83g) all-purpose flour


  1. Adjust an oven rack to the middle position and preheat the oven to 176°F.

  2. Cover a 9x13-in metal baking pan with heavy-duty aluminum foil (see note below). Push the foil neatly into the corners and up the sides of the pan, using two pieces if necessary to ensure that the foil overlaps all edges (the overhang will help removal from the pan). Spray the foiled pan with nonstick cooking spray.

  3. Place the flour, corn starch, salt and Confectioners' sugar in the bowl of a food processor fitted with the blade attachment and mix for a few seconds. Add the butter and mix to blend until the mixture resembles coarse meal, 10 to 15 seconds. Sprinkle the mixture into the prepared pan and press firmly with your fingers into an even layer, building up a thin ¾-inch edge around the sides (this keeps the filling from spilling beneath the crust). Refrigerate for 30 minutes or freeze for 15 minutes.

  4. Bake the crust until lightly golden, 15 to 20 minutes.

  5. In a large bowl, whisk together the eggs, sugar, lemon juice, lemon zest, and flour. Be sure no lumps of flour remain.

  6. When the crust is ready, give lemon mixture a quick final stir and then pour over top. Immediately return the pan to the oven and bake another 30 to 35 minutes, or until the topping is set and firm. Let the bars cool on a rack to room temperature; it will take several hours.

  7. To cut, use the foil overhang to lift the baked square out of pan and onto a cutting board. Carefully loosen the foil from the edges of the crust, using a knife if necessary. Using a sharp knife, cut into squares or triangles. Use a fine sieve to dust the squares with Confectioners' sugar. Store the bars in a covered container in the refrigerator for up to 4 days. Serve chilled or room temperature.

Note: Be sure to use heavy-duty aluminum foil; regular aluminum foil may stick. Parchment paper can also be used to line the pan.
