Lemon Bars

Recipe from allrecipes.com

1 cup butter, softened
1/2 cup powdered sugar
2 cups all-purpose flour

4 eggs
1 1/2 cups sugar
1/4 cup all-purpose flour
2 lemons, juiced

Directions
Preheat oven to 350 degrees F (175 degrees C).
In a medium bowl, blend together softened butter, 2 cups flour and 1/2 cup sugar. Press into the bottom of an greased 9x13 inch pan.
Bake for 15 to 20 minutes in the preheated oven, or until firm and golden. In another bowl, whisk together the remaining 1 1/2 cups sugar and 1/4 cup flour. Whisk in the eggs and lemon juice. Pour over the baked crust.
Bake for an additional 20-25 minutes in the preheated oven. The bars will firm up as they cool.
