In a Ziplock bag, mix the milk and pickle juice, then add in the chicken nugget pieces.
Squeeze the bag to be sure the nuggets are covered with the marinade.
Refrigerate them in the marinade for at least a half hour, about 3-6 hours is even better! No more than overnight though. You don’t want the pickle juice to be too prominent!
In a medium bowl, mix the flour, breadcrumbs, powdered sugar, garlic powder, salt, paprika, baking powder, and black pepper. Cover the bowl and set it aside at room temperature.
When ready to fry, put the oil at least one inch deep into a deep fryer and heat the oil to 350°F.
Drain the chicken nuggets from the marinade. Discard the marinade.
Dredge the chicken nuggets in the coating mixture.
Fry them in the oil for 4-5 minutes or until golden brown.
Place them on a plate lined with paper towels.
Serve immediately.
