Preheat oven to 350 degrees F and grease a bundt pan with nonstick cooking spray.
In a small bowl, mix together the olive oil, butter, garlic, and Italian seasonings and set aside.
Open and separate the biscuit dough cans, then cut each biscuit into four pieces. Roll a handful of the cut biscuit pieces into the garlic butter mixture at a time, making sure to cover all the dough, then transfer to a separate large bowl. Continue until all of the biscuit pieces are covered.
Add the pepperoni, mozzarella cheese, and Parmesan cheese to the bowl with the biscuit pieces, tossing gently to combine. Spread the prepared pizza monkey bread pieces evenly into the bundt pan.
Bake in a preheated oven for 30-35 minutes, or until the edges are golden brown and the dough is cooked through.
Remove the pan from the oven and let it sit for 10 minutes before inverting it to a large plate or serving platter. Serve with warm marinara sauce. Enjoy!
