Slice the chicken into thicker pieces and set aside.
You need enough oil for deep frying, in dependence of the saucepan you are using, it should be enough so the chicken pieces don't sink to the bottom of the pot and should be covered in oil.
Add the oil to a deep-fryer or large saucepan and heat it up to 375 degrees F / 190 degrees C. Use a kitchen thermometer to measure the temperature.
In a small bowl, combine flour, salt, black pepper, cayenne pepper, paprika, garlic powder and set aside.
In another small bowl, whisk together egg and milk. Set aside.
Cover a baking sheet with parchment paper or foil. Set aside.
Dip each piece of chicken in the egg mixture, then roll it in the seasoned flour mixture. Place on the prepared baking sheet.
Repeat so each piece of chicken is double coated.
Refrigerate breaded chicken for 20-30 minutes.
Working in batches, so the saucepan is not over-crowded, fry chicken until golden brown, about 5 to 6 minutes per batch.
