Preheat oven to 400ºF. Spray skull mold with nonstick spray. Set aside.
Unroll pizza dough and stretch or roll into a 21x 8-inch rectangle with the long edge closest to you. Cut into six even strips.
Lay dough into skull cavities, press down lightly, and leave flaps over pan for closing the pizza pockets.
Into each cavity, layer 1 tablespoon shredded mozzarella, 1 tablespoon of grated parmesan, 1 tablespoon pizza sauce, 3 pepperoni, another tablespoon sauce, 1 more tablespoon mozzarella, and a sprinkle of seasoning.
Fold dough over fillings and pinch dough together to seal, making sure edges are sealed tightly. Repeat for the five remaining pizza pockets.
Bake for 20 minutes, remove from oven and let cool slightly, flip plan onto serving platter.
Serve with warmed pizza sauce and additional Parmesan cheese for topping.
You can use any topping you like instead of the pepperoni. Try chunked ham, diced veggies, or just add a little shredded cheddar in for a 3-cheese pizza pocket.
