01 - Set up three shallow bowls: place flour in the first bowl, whisk eggs with milk in the second bowl, and combine panko, Parmesan, oregano, garlic powder, salt, and pepper in the third bowl.
02 - Pat mozzarella cubes dry with paper towels to remove excess moisture.
03 - Dredge each mozzarella cube in flour, shaking off excess. Dip into egg mixture, then coat thoroughly in breadcrumb mixture. For extra-crispy crust, repeat egg and breadcrumb steps.
04 - Place coated cheese balls on a tray and freeze for 15 minutes to help prevent melting during frying.
05 - In a deep saucepan or fryer, heat oil to 350°F.
06 - Fry cheese balls in batches for 1 to 2 minutes until golden and crisp. Remove with slotted spoon and drain on paper towels.
07 - Serve hot with marinara sauce or your favorite dip.
