Preheat your oven to 375°F (190°C).
In a mixing bowl, blend the softened cream cheese until smooth.
Stir in the pizza sauce, garlic powder, and Italian seasoning until well combined.
Add the shredded mozzarella and grated Parmesan, mixing until evenly distributed.
Fold in the sliced pepperoni so it’s evenly spread throughout the mixture.
Transfer the mixture into a greased baking dish, smoothing the top with a spatula.
Bake in the preheated oven for 20-25 minutes, or until the cheese is bubbling and golden brown.
Remove from the oven and let it cool for a few minutes before garnishing with fresh parsley.
