Prepare Batter: Preheat oven to 350 F. Let eggs, butter, and milk stand at room temperature for 30 minutes. In a medium bowl combine cake flour, baking powder, and salt; set aside.
Butter two 8″ x 1.5″ round cake pans and line bottoms with waxed paper. Butter waxed paper and lightly flour; set aside.
In large mixing bowl, beat butter with an electric mixer on MED/HIGH for 30 seconds.
Add 2 cups sugar and 1 tablespoon vanilla; beat 3 to 4 minutes on MEDIUM until well combined.
Add eggs, one at a time, beating well after each addition. Alternately add flour mixture and milk to butter mixture, beating on LOW after each addition until just combined.
Divide batter between the two pans.
Bake 20-25 minutes or until tops spring back when lightly touched or a toothpick comes out clean.
Cool layers in pans on wire racks for 10 minutes. Remove the cake layers from pans; peel off waxed paper and discard. Cool on wire racks.
