Lemon Bars

For the crust:
1 cup unsalted butter, softened
1/2 cup granulated sugar
2 cups flour
1/8 tsp kosher salt

For the filling:
6 eggs
3 cups granulated sugar
2 Tbsp grated lemon zest (4 to 6 lemons)
1 cup freshly squeezed lemon juice
1 cup flour
Confectioners' sugar, for dusting

Set oven to 350 degrees F.

For the crust, cream the butter and sugar in a mixing bowl until light. Combine the flour and salt and with the mixer on low, add to the butter until just mixed. Flatten the dough with floured hands and press it into a greased 9 x 13 x 2 inch baking sheet, building up a 1/2 inch edge on all sides. Chill for 15 minutes.Bake the crust for 15 to 20 minutes, until very lightly browned. Let cool on a wire rack. Leave the oven on.

For the filling, whisk together the eggs, sugar, lemon zest, lemon juice, and flour. Pour over the crust (crust does not need to be completely cooled) and bake for 30 to 35 minutes, until the filling is set. Let cool to room temperature.Cut into squares and dust with confectioners' sugar.
