01 - Cut the mozzarella block into 18 even cubes or rectangles, approximately 1 inch each.
02 - Prepare three bowls: one with flour, one with beaten eggs, and one combining panko breadcrumbs, garlic powder, smoked paprika, salt, and black pepper.
03 - Coat each mozzarella piece in flour, dip into beaten egg, then press thoroughly into the panko mixture. For extra crunch, double-dip by returning to the egg and panko a second time.
04 - Arrange the breaded mozzarella pieces on a baking tray and freeze for 20 minutes to firm them up and prevent cheese leakage during frying.
05 - Pour vegetable oil into a deep pan or heavy-bottomed pot and heat to 350°F over medium-high heat.
06 - Fry the mozzarella poppers in batches for 2 to 3 minutes, turning occasionally, until golden brown and crisp. Remove with a slotted spoon and drain on paper towels.
07 - Combine maple syrup, Dijon mustard, unsalted butter, smoked paprika, and a pinch of salt in a small saucepan. Simmer over low heat for 2 to 3 minutes until slightly thickened, then set aside.
08 - Drizzle the warm maple glaze over the hot mozzarella poppers, or serve the glaze on the side as a dipping sauce. Serve immediately.
