Heat the oven to 450°F and line two baking sheets with parchment paper.
Divide the dough into four equal pieces and roll each into a 6-inch round. Place the rounds on the prepared sheets.
Spread 3 tablespoons of pizza sauce over each round, leaving a ½-inch border.
Sprinkle ½ cup of mozzarella evenly over the sauce on each pizza.
Use the remaining cheese to draw a spiderweb on top of each pizza: make three concentric circles with thin lines of cheese, then add eight short lines from the center outward like spokes.
Place two olive slices in the center of each web to form a small spider.
Bake for 10 to 12 minutes until the crust is golden and the cheese is melted and lightly browned.
Remove from the oven and let the pizzas rest for 2 minutes before slicing.
