Spray your crock pot with nonstick cooking spray.
Spread the softened cream cheese evenly on the bottom.
Sprinkle with 1 cup of mozzarella cheese, ½ tablespoon of Italian seasoning, and garlic powder.
Layer half of the pepperoni on top.
Spread pizza sauce evenly over the pepperoni.
Add cheddar cheese, the remaining mozzarella, the rest of the Italian seasoning, and finish with the remaining pepperoni.
Cover and cook on low for 2 hours or high for 1 hour, until hot and bubbly.
Switch to the warm setting to serve, or let cool to room temperature. Both ways are delicious!
Serve with garlic bagel chips for dipping.
