Preheat your oven to 375°F (190°C) and line two baking sheets with parchment paper.

Dust your work surface with all-purpose flour, divide the pizza dough into 10 equal pieces, and roll each into an 8-inch rope.

Snip each end of the rolled dough about 1 inch deep and pull the ends apart to resemble bones, then arrange them on the baking sheets.

Brush melted unsalted butter over each breadstick and sprinkle with grated Parmesan cheese.

Bake for 15 minutes until lightly golden, then add shredded mozzarella on top and bake for an additional 5-7 minutes.

Remove from oven, let cool slightly, and serve warm with marinara sauce for dipping.
