In a wide bowl add the corn flakes and set aside. In a separate bowl combine the eggs, buttermilk, vanilla extract, cinnamon, salt and nutmeg and whisk to combine.
One at a time, take one finger roll (or thick white bread) and dip it in the egg mixture letting the excess drain off. Then dip the bread in the corn flakes completely coating both sides. Set aside and repeat until all slices are coated.
Heat a large skillet and add butter. When butter is melted and bubbling add prepared bread slices and cook until golden brown, about 3-5 minutes. Flip and repeat on the other side. Repeat this until all french toast slices are golden and crispy.
Serve warm with your favorite toppings, and enjoy!
