Preheat the oven to 350 degrees Fahrenheit. Spray a bundt pan with nonstick cooking spray and set aside.
Cut the biscuits into quarters and slice the pepperoni pieces in half.
In a large bowl, add the biscuit pieces, pepperoni, mozzarella cheese, parmesan cheese, Italian seasoning, melted butter, garlic powder, and garlic salt. Toss to combine.
Bake for 35-40 minutes. Cover with foil for the last 10 minutes to prevent it from browning too much.
Using hot pads, carefully flip the bundt pan over on a large plate. Serve with marinara sauce and enjoy!
Notes
If you happen to have leftover pizza monkey bread, place it in an airtight container and store it in the refrigerator for 3 to 5 days. To reheat, place your serving on a microwavable plate and microwave for 1 minute or until it is warmed through. Alternatively, you can reheat in a toaster oven or air fryer for a couple of minutes.
