1In a large bowl, combine the buttermilk and chicken drumsticks. Cover and refrigerate for at least 2 hours, or overnight for best results.
In another large bowl, mix together the flour, paprika, garlic powder, onion powder, salt, black pepper, and cayenne pepper.
Remove the chicken from the buttermilk, allowing any excess to drip off. Dredge each drumstick in the flour mixture, ensuring an even coating.
Heat the vegetable oil in a deep fryer or large pot to 350°F (175°C).
Carefully place the coated chicken drumsticks into the hot oil, frying in batches to avoid overcrowding. Fry each batch for about 12-15 minutes, or until the chicken is golden brown and cooked through.
Remove the fried chicken from the oil and place on a paper towel-lined plate to drain any excess oil.
Serve hot and enjoy your Classic KFC Style Fried Chicken!
