01 - Cut the mozzarella block into 18 uniform cubes or rectangles, approximately 1 inch each.
02 - Arrange three separate bowls: one containing the flour, one with the beaten eggs, and one combining the panko breadcrumbs with garlic powder, smoked paprika, kosher salt, and black pepper.
03 - Dredge each mozzarella piece through the flour, submerge in the beaten egg, then press firmly into the seasoned panko mixture, ensuring full coverage. For an extra-crispy crust, repeat the egg and panko steps a second time.
04 - Arrange the breaded mozzarella pieces on a lined baking sheet and freeze for 20 minutes to firm up the coating and prevent cheese from leaking during frying.
05 - Pour vegetable oil into a deep skillet or heavy-bottomed pan to a depth of about 2 inches and heat to 350°F over medium-high heat.
06 - Working in batches of 5 or 6, fry the mozzarella poppers for 2 to 3 minutes, turning occasionally, until deeply golden and crisp on all sides. Remove with a slotted spoon and transfer to a paper towel-lined plate to drain.
07 - In a small saucepan, combine the maple syrup, Dijon mustard, unsalted butter, smoked paprika, and a pinch of salt. Simmer over low heat for 2 to 3 minutes, stirring occasionally, until the glaze thickens slightly. Remove from heat and set aside.
08 - Drizzle the warm maple glaze over the hot mozzarella poppers, or serve the glaze alongside as a dipping sauce. Serve immediately while hot and crispy.
