Preheat your oven to 400 F degrees. Spray a large skillet with cooking spray, if required. At this time you can take out the frozen dinner rolls from the freezer, they do not need to be thawed out.
Whisk together the butter, garlic, parsley, red pepper flakes, salt and pepper in a small bowl. Roll the frozen bread rolls through the butter mixture then arrange them around the outside of the edge of the skillet. Cover with a clean tea towel and let the bread rolls thaw out for about 20 minutes.
In the meantime, in a medium size bowl add the cream cheese, mayonnaise, Italian seasoning, red pepper flakes, salt, pepper, Parmesan cheese and mix well using a spatula until everything is well combined. Add about 1 1/2 cups of the Mozzarella cheese to the mixture and mix to combine.
Spoon about half of the cheese mixture into the center of the skillet and spread it. Add the pizza sauce and spread it over the cheese mixture then spoon the rest of the cheese mixture. Sprinkle with the remaining half cup of mozzarella cheese then top with the pepperoni slices.
Place the skillet in the oven and bake for 20 to 25 minutes or until the bread rolls are baked and golden brown and the pizza dip is hot and bubbly.
Garnish with parsley and serve warm.
