Preheat oven to 350 degrees Fahrenheit. Spray a 10-inch Bundt pan with cooking spray.

Cut the biscuit dough rounds into quarters. If using pizza dough, cut it into thick 2-inch chunks.

In a large bowl, combine the biscuit dough pieces, three cheeses, pepperoni, garlic, Italian seasoning, and melted butter. Using your hands, mix all of the ingredients together until it's well blended and the dough chunks are coated with the butter, cheese, and seasoning.

Scoop the mixture into the prepared bundt pan, making sure it's an even layer. Bake for 20 minutes, then remove from oven and cover with tin foil to prevent the top from over browning. Return the foil-covered pan to the oven and cook for an additional 15 to 25 minutes, or until the dough is completely cooked (use a knife to pull apart the bread in the center to make sure it is not still dough in the middle.)

Turn the pizza monkey bread out onto a plate and then invert it again onto your serving platter so that the top is right side up. Brush lightly with olive oil and sprinkle with additional grated Parmesan, red pepper flakes, and fresh basil. Serve warm with marinara sauce for dipping.
