Unpackage the pizza dough and cut it in half lengthwise. Roll the dough into 2 long ropes. Cut into 1-inch pieces.
Place the dough pieces on a baking sheet lined with parchment paper.
Combine the melted 4 Tbsp. butter, garlic, salt and 2 Tbsp. of Parmesan in a small bowl. Using a pastry brush, brush the dough pieces with the melted butter mixture.
Bake for 15 minutes.
Melt the remaining 1 Tbsp. of butter and brush the baked Parmesan bites while still hot. Sprinkle with remaining Parmesan cheese.
