Preheat the Oven: Set your oven to 375°F and allow it to heat up. While waiting, prepare two baking sheets by lining them with parchment paper to prevent the breadsticks from sticking.
Shape the Dough: Take your pizza dough and divide it into 10 equal portions. Roll each portion into a rope about 8 inches long. To create the “bone” effect, make sure the ends of each rope are slightly thicker than the middle. Place the shaped dough onto the prepared baking sheets, leaving some space between each piece so they don't touch while baking.
Snip the Ends: Grab your kitchen scissors and make two small cuts (about 1 inch deep) on both ends of each dough rope. Gently pull and stretch these cut pieces apart to create the shape of bone ends.
Brush and Bake: Melt the butter and, using a pastry brush, generously coat each breadstick with it. Sprinkle the grated Parmesan cheese over the top for extra flavor. Place the breadsticks in the oven and bake for about 15 minutes, or until they begin to turn golden.
Add Mozzarella: After 15 minutes, take the breadsticks out of the oven. Sprinkle the shredded mozzarella cheese evenly over each one, then return them to the oven. Bake for another 5 to 7 minutes, or until the mozzarella has melted and is bubbling.
Serve: Once the breadsticks are out of the oven, serve them warm with a side of marinara sauce for dipping. Enjoy the spooky, cheesy snack!
