Preheat oven to 350°F. Grease and flour two 9-inch round cake pans. In a medium bowl, whisk together cake flour, baking powder, and salt. In a large bowl, beat eggs with granulated sugar until thick and pale. Add melted butter and vanilla extract, mixing until incorporated. Alternate adding dry ingredients and milk in batches, mixing just until combined.
