Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.
Lightly flour a surface and roll out pizza dough to about 1/4 inch thick. Cut into 3–4 inch circles using a cookie cutter or glass.
Place dough rounds on the prepared baking sheet.
Spread each with a thin layer of pizza sauce.
Top with shredded mozzarella cheese.
Decorate: use pepperoni to make pumpkin faces, black olives for spider bodies with sliced olive legs, or strips of string cheese laid across to create a mummy effect.
Add olive pieces or candy eyeballs to make spooky faces.
Bake for 10–12 minutes, or until cheese is melted and bubbly and crust is golden.
Serve warm and enjoy your Halloween-themed mini pizzas!
