Lemon Squares

1 cup butter, softened 

1/2 cup white sugar
2 cups all-purpose flour
4 eggs
1 1/2 cups white sugar
1/4 cup all-purpose flour
2 lemons juiced or 2/3 cup bottled lemon juice

Powdered or confectioners sugar

Preheat oven to 350 degrees F (175 degrees C). Spray a 9x13 pan with nonstick spray.

In a medium bowl, blend together softened butter, 2 cups flour and 1/2 cup sugar. Press into the bottom of the 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 minutes in the preheated oven. Cool completely and sprinkle with powdered sugar.
