Spread some butter along the bottom and side of a deep 10 inch round cake pan or 13×9 inch regangular baking pan.
Combine the flour, salt and baking powder in a large bowl and set aside.
Using another bowl, combine the eggs, vanilla, and sugar and beat with an electric hand mixer until it triples in volume about 8-10 minutes.
Using a whisk or spatula, carefully fold into the dry flour mixture.
