01 - Slice the mozzarella block into 18 uniform cubes or rectangles, approximately 1 inch each.
02 - Arrange three shallow bowls: the first with flour, the second with beaten eggs, and the third with panko breadcrumbs combined with garlic powder, smoked paprika, salt, and black pepper.
03 - Dredge each mozzarella piece through the flour, then dip into the beaten egg, and press firmly into the seasoned panko mixture until fully coated. For an extra-crisp crust, repeat the egg and panko steps a second time.
04 - Arrange the breaded pieces on a parchment-lined baking sheet and freeze for 20 minutes. This step firms the cheese and prevents blowouts 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 - Working in batches of 5 or 6, fry the frozen mozzarella poppers for 2 to 3 minutes, turning occasionally, until deeply golden and crisp. Transfer to a paper towel–lined plate using a slotted spoon or tongs.
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.
08 - Drizzle the warm maple glaze over the hot poppers, or serve it alongside as a dipping sauce. Serve immediately while the cheese center is still molten.
