2 cup all-purpose flour
1 cup confectioner's sugar
Pinch of salt
1 cup (2 sticks) butter, at room temperature
2 cups granulated sugar
6 Tbsp all purpose flour
6 Tbsp lemon juice
Preheat the oven to 350 degrees. Lightly grease a 9x13 pan. Make the crust: combine flour, confectioner's sugar, and salt in a large bowl. Cut in the butter to make a crumbly mixture. Press the mixture into the prepared pan. You may need to dip your fingers into a little flour or confectioner's sugar to keep the dough from sticking to your fingers. Bake for 20 min.
Meanwhile, make the filling: mix the eggs, granulated sugar, flour, and lemon juice. Pour this over the baked crust and bake for 25 minutes longer. Sprinkle with confectioner's sugar, if desired, when the bars are done.
