01 - Preheat your oven to 350°F (175°C). Grease a Bundt pan or a deep round baking dish thoroughly with olive oil.
02 - Open the refrigerated biscuit dough cans and carefully cut each biscuit into four equal pieces.
03 - In a large mixing bowl, combine the biscuit pieces, shredded mozzarella cheese, mini pepperoni slices, grated Parmesan cheese, dried Italian herbs, garlic powder, and crushed red pepper flakes. Toss gently to distribute.
04 - Pour one cup of pizza sauce over the combined ingredients. Toss gently again until all pieces are evenly coated with the sauce.
05 - Transfer the mixture into the prepared Bundt pan or baking dish. Press down lightly to ensure an even layer.
06 - Drizzle the melted unsalted butter evenly over the top of the mixture in the pan.
07 - Bake for 30 to 35 minutes, or until the bread achieves a golden brown color and is cooked through. A skewer inserted into the center pieces should come out clean.
08 - Allow the bread to cool in the pan for 10 minutes. Then, carefully invert the entire pan onto a serving plate.
09 - Brush the top with additional melted butter and sprinkle with fresh chopped parsley, if desired, for extra flavor and visual appeal.
10 - Serve the pull-apart bread warm, accompanied by extra pizza sauce for dipping.
