Preheat oven to 350°F. Oil (or Spray with Cooking Spray) a Bundt pan and then dust with flour.
Mix Dry ingredients: In a medium mixing bowl, mix flour, cornmeal, baking power, and salt. Set aside.
Separate Eggs. If you have not done so, separate egg whites from the yokes, the whites going into a medium mixing bowl for whipping up and the yokes going into a large mixing bowl. Set aside the egg whites.
To the large mixing bowl with the yokes, whisk in the Sugar until smooth. Next whisk in the milk and oil. Finally, whisk in the flour mixture.
Now, using a hand mixer, whip the egg whites until soft peaks have formed. Then gently fold into the batter.
Pour the batter into the oiled bundt pan. Bake for 30 minutes or until a toothpick inserted into the center comes out clean.
Cool the cake in the pan for 15 minutes. Then, gently run a knife around the outside of the cake inside the pan and flip the cake out into your hands and gently place it right side up onto a serving platter to continue cooling. You can dust with powdered sugar if you want. Enjoy!
