In a bowl mix together the All-Purpose Flour (1 cup), Salt and Pepper (to taste), and Garlic Powder (1 teaspoon). In another bowl mix together the Egg (2) and Milk (1/4 cup). In a third and separate bowl, crush the Corn Flakes (2 cup) into small pieces.
Cut your Fish Fillet (4) into small pieces and dip each piece into the flour mix, the egg and the cornflakes. Place the fish in a separate dish, cover them with a plastic cover and put them in the fridge for about half an hour.
Preheat your oven to 200 degrees C (400 degrees F).
On a baking dish lined with baking paper, place your fish and spray them with some oil. Bake inside a preheated oven, 200 degrees C (400 degrees F) for about half an hour.
