Preheat oven to 350 degrees F
In a medium bowl, combine ingredients for the crust (softened butter, 2 cups flour, 1/2 cup sugar and salt).
Press the dough in an ungreased 9x13 inch pan. Use a fork to poke holes in the dough.
Bake the crust for 15 minutes until firm and golden.
In another bowl, whisk the eggs, lemon juice, and white sugar. Then add the flour.
Take the crust out of the oven and let it cool for a few minutes.
Pour the custard mixture in the baked crust and put it back in the oven for 15 mins.
Let the lemon bars cool to room temperature.
Cut the lemon bars into squares then sprinkle powdered sugar on top.
