Prepare Your Baking Sheet and Toppings
First, preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper. Arrange the English muffin halves on the sheet. If desired, lightly brush each half with melted butter or olive oil for extra flavor and crispiness.

Assemble the Mini Pizza Bases
Next, spoon about one to two tablespoons of sauce onto each muffin half, spreading it evenly. Afterwards, sprinkle a small pinch of dried oregano or basil over the sauce for that classic pizzeria taste.

Craft Your Mozzarella Ghosts
Now, use a small, ghost-shaped cookie cutter to press out shapes from your mozzarella slices. If you don’t have one, a small paring knife works just as well to carefully cut out wavy, ghost-like shapes by hand.

Bake Your Ghost Mini Pizzas
Carefully place one mozzarella ghost onto each sauced muffin half. Then, bake for 8 to 10 minutes, or until the cheese is fully melted and the muffin edges are golden brown.

Add the Final Ghostly Details
Once baked, remove the pizzas from the oven and let them cool for a minute. Finally, use tiny pieces of black olive to carefully create eyes and mouths for your ghosts.
