The document provides a recipe for lemon bars. It instructs the user to mix confectioners' sugar, flour, and margarine together to form a crust that is pressed into a 9x13 inch pan and baked for 22 minutes. While the crust bakes, a topping of flour, sugar, eggs, lemon juice, and baking powder is mixed. Once the crust is done, the topping is poured over and baked again at 350 degrees for 22 more minutes. Once cooled, confectioners' sugar is sprinkled on top.
