Combine eggs with corn muffin mix in a large mixing bowl. Add corn and buttermilk. Mix until batter is moistened and combined. Stir in cheese. Pour into a greased baking dish.
Bake at 400 for 20-25 minutes or until golden and set. Let sit 5 minutes before cutting.
Leftovers freeze beautifully
Notes
*make your own buttermilk by adding 1 Tablespoon of lemon juice or vinegar to a scant 1 cup of milk and let it sit for 5 minutes
