Using a tablespoon measure or small cookie scoop, portion the cold goat cheese into 12 equal-sized balls. Roll each one between your palms quickly - the cheese is easier to shape when very cold. Place the balls on a parchment-lined plate and freeze for at least 30 minutes until firm. This step is essential to prevent the cheese from melting apart during cooking.
Set up a breading station. Place the flour in the first shallow dish. Beat the egg with the water in the second dish. In the third dish, combine the panko, parsley, garlic powder, italian seasoning, and black pepper.
Remove the frozen goat cheese balls from the freezer. Roll each ball in flour, dip into the egg wash, then coat generously in the panko mixture, pressing gently to adhere. For an extra-thick crust, dip again in egg and then panko for a double coat.
Place the breaded balls back on the parchment-lined plate and return them to the freezer for another 15 minutes.
Preheat the air fryer to 400 degrees F for 3 minutes. Spray the basket with olive oil spray. Arrange the frozen breaded goat cheese balls in a single layer and spray the tops with olive oil spray.
Air fry at 400 degrees F for 6 to 8 minutes, turning them gently halfway through, until the coating is golden and crispy.
Transfer to a plate immediately, drizzle with honey, and serve right away while the center is warm and creamy. Offer marinara sauce on the side for dipping if desired.
