Preheat oven to 350°. Combine corn kernels, cream-style corn, red peppers, sour cream, egg yolks, hot pepper sauce, butter, and corn muffin mix. Coat a 9x13-inch baking dish with nonstick cooking spray. Beat egg whites to a soft peak and fold into the batter. Pour into the baking dish, then bake 45 to 50 minutes until set (lightly browned, yet springy in the center).
