Crack eggs into a small bowl and whisk lightly, set aside. If making your own buttermilk, do so at this time and set aside.
Melt butter in a medium pot/skillet. Remove from heat and stir in sugar. Quickly add in eggs and beat with a whisk until well blended. Combine buttermilk with baking soda and stir into mixture in pot. Stir in cornmeal, flour, salt and corn until well blended and few lumps remain. Pour batter into pan.
