In a mixing bowl, combine the finely shredded chicken and buffalo sauce until the protein is evenly hydrated.
Press approximately 2 tablespoons of the buffalo chicken mixture around each mozzarella stick, compressing firmly with your hands to form a cohesive cylinder.
Arrange the chicken-wrapped sticks on a parchment-lined sheet and freeze for 60 minutes to ensure structural stability during the breading process.
Organize a standard breading station consisting of flour in the first container, whisked eggs in the second, and panko mixed with garlic powder in the third.
Dredge each frozen stick in flour, submerge in the egg wash, and coat thoroughly with panko breadcrumbs.
Repeat the egg and panko coating a second time to create a double-layered barrier against cheese leakage.
Heat the frying oil in a heavy-bottomed vessel to a stable temperature of 350°F (175°C).
Submerge the sticks in batches, frying for 120 to 180 seconds until the exterior reaches a golden-brown hue.
Extract with a slotted spoon and drain on a wire rack for 2 minutes to allow the internal temperature to stabilize before serving.
