Preheat your oven to 350 degrees Fahrenheit. Grease a bundt pan with nonstick cooking spray and set it aside.
Cut the refrigerated canned biscuits into quarters and slice the pepperoni pieces in half.
In a large mixing bowl, combine the biscuit pieces, sliced pepperoni, mozzarella cheese, parmesan cheese, melted butter, Italian seasoning, garlic powder, and garlic salt. Toss until all the ingredients are evenly distributed.
Transfer the mixture into the prepared bundt pan, spreading it out evenly.
Bake for 35-40 minutes, ensuring to cover the pan with foil for the last 10 minutes to prevent excessive browning.
Once baked, carefully invert the bundt pan onto a large plate to release the pizza monkey bread.
Garnish with fresh parsley and serve warm with marinara sauce for dipping.
