01 - Cut the mozzarella block into 18 even cubes or rectangles, approximately 1 inch each.
02 - Prepare three shallow 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 firmly into the panko mixture. For extra crunch, repeat the egg and panko steps a second time.
04 - Arrange the breaded pieces on a parchment-lined baking tray and freeze for 20 minutes to firm up the cheese and prevent leakage during frying.
05 - Pour vegetable oil into a deep pan or heavy-bottomed pot to a depth of about 2 inches. Heat to 350°F over medium-high heat.
06 - Fry the frozen mozzarella poppers in batches of 5–6 for 2 to 3 minutes, turning occasionally, until deep golden brown and crisp. Remove with a slotted spoon and drain on paper towels.
07 - In a small saucepan, combine maple syrup, Dijon mustard, unsalted butter, smoked paprika, and a pinch of salt. Simmer over low heat for 2 to 3 minutes until slightly thickened, then remove from heat.
08 - Drizzle the warm maple glaze over the hot poppers, or serve the glaze alongside as a dipping sauce. Serve immediately while hot and crispy.
