Preheat your oven to 400°F (204°C) to ensure even baking.

Lightly spray a mini skull baking tin with cooking spray.

Roll out your pizza dough to about 1/4 inch thick and slice into rectangles.

Press each rectangle into a skull cavity, then spoon in pizza sauce, mozzarella, parmesan, and your chosen toppings.

Seal the skulls by placing sauce on top and folding the excess dough over.

Chill the filled baking tin in the refrigerator for about 10-15 minutes.

Bake in the preheated oven for 16-20 minutes until golden brown.

Let cool for about 5 minutes before unmolding and serving with marinara sauce.
