Set the oven to 400°F (200°C). Prepare an 8-inch springform pan and place it on a half-sheet tray to catch any overflow.
Prepare the pretzel bites:
Using a sharp knife, carefully slit each pretzel bite approximately 70% of the way through, similar to slicing a small bun. Fill each bite with about one teaspoon of chive cream cheese.
Create the butter mixture:
In a medium bowl, combine the melted butter, minced garlic, whole grain mustard, Dijon mustard, and grated parmesan. Stir until well blended.
Assemble the first layer:
Arrange half of the stuffed pretzel bites in the prepared pan. Brush generously with half of the butter mixture, then sprinkle with half of the grated mozzarella.
Repeat and finish layering:
Place the remaining stuffed pretzel bites on top, brush with the remaining butter mixture, and finish with the remaining mozzarella.
Bake:
Transfer the pan to the oven and bake for 12–15 minutes, or until the cheese is golden and bubbling.
Serve:
Allow to cool briefly before serving. Present with cheese sauce or dipping sauce of choice.
