Combine Ingredients: In a 6-quart slow cooker, add cream cheese, 1½ cups of shredded mozzarella, pizza sauce, Italian seasoning, onion powder, garlic powder, and half of the mini pepperoni. Stir until well combined.
Cook: Cover and cook on high for 1½ hours or low for 2–3 hours, stirring occasionally to ensure even melting and flavor.
Add Toppings: Sprinkle the remaining mozzarella cheese and pepperoni on top. Cover and cook for an additional 10–15 minutes, or until the cheese is melted and bubbly.
Serve: Scoop warm with toasted bread, baguette slices, crackers, or tortilla chips. Enjoy every gooey bite!
