01 - Cut the mozzarella block into 18 uniform cubes or rectangles, approximately 1 inch each.
02 - Arrange three shallow bowls: one with flour, one with beaten eggs, and one combining panko breadcrumbs, garlic powder, smoked paprika, salt, and black pepper.
03 - Dredge each mozzarella piece in flour, dip into beaten egg, then press firmly into the seasoned panko mixture. For an extra-crisp coating, repeat the egg and panko steps a second time.
04 - Arrange the breaded pieces on a baking sheet lined with parchment paper and freeze for 20 minutes to firm up the cheese and prevent blowouts during frying.
05 - Heat vegetable oil in a deep pan to 350°F. Fry the mozzarella poppers in batches for 2 to 3 minutes, turning occasionally, until deeply golden and crisp. Remove with a slotted spoon and drain on paper towels.
06 - 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 remove from heat.
07 - Drizzle the warm maple glaze over the hot poppers, or serve the glaze alongside as a dipping sauce. Serve immediately for the best texture.
