Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.

Lightly flour your work surface, roll the pizza dough into a ¼-inch-thick rectangle, and cut out 8 mini rounds with a cutter or glass.

Arrange the rounds on the prepared sheet and spread a thin layer of pizza sauce on each, leaving a small border.

Bake for 8–10 minutes until the edges turn lightly golden and the tops begin to bubble.

While baking, cut ghost shapes from the mozzarella slices using a paring knife or cookie cutter.

Remove the pizzas, place a ghost cheese shape on each, and bake for 4–5 more minutes until the cheese melts but keeps its shape.

Let cool briefly, then serve warm with gooey cheese and a crisp crust.
