In a medium sized bowl, add the cream cheese, sour cream, oregano, basil, garlic, salt, parmesan and 2 cups of the mozzarella cheese. Whip together using a handheld electric mixer.
Add the cream cheese mix to a 4 quart or larger slow cooker and spread evenly.
Top the cream cheese mixture with the pizza sauce and spread evenly.
Sprinkle on the remaining 1 cup of mozzarella cheese, and evenly place the ¼ cup of mini pepperonis.
Cook on LOW for 3 hours or on HIGH for 2 hours.
Garnish with fresh basil and serve with dippers. Enjoy!
