Preheat oven to 350 degrees F. Meanwhile, lightly grease the bottoms of two 8-inch round cake pans. Line bottoms of pans with waxed paper or parchment paper; grease and lightly flour pans. In a large bowl, beat eggs with a mixer on high about 4 minutes or until thickened and light yellow in color. Gradually add sugar, beating on medium speed for 4 to 5 minutes or until light and fluffy. Add flour, baking powder, and salt. Beat on low to medium just until combined.
