Spray a (13x9-inch) baking pan with baking spray. Line with parchment paper, and spray again. Set aside.
In a medium bowl, beat eggs, vanilla, and sugar at high speed with an electric mixer until light and fluffy, approximately 5 minutes.
Sift flour and salt over egg mixture. Gently fold in. Spread batter into prepared pan.
Bake until a wooden pick inserted near center comes out clean, approximately 8 minutes. Cool in pan for 10 minutes. Remove to a wire rack to cool completely.
