Preheat the oven to 350 degrees F. Grease a 10-cup or larger Bundt pan.
In a large bowl, stir together the olive oil, Italian seasoning, and garlic powder.
One at a time, unroll each can of pizza dough and use a sharp knife or pizza cutter to slice the dough into 1-inch squares.
Roll each square of dough into a ball and put it into the bowl with the oil. Add the pepperoni and mozzarella.
Gently stir all ingredients together to coat with the seasoned olive oil.
Pour into the greased Bundt pan. Cover with foil and cook for 15 minutes. Remove the foil and cook another 25-30 minutes until cooked through and golden brown.
Allow the pizza bread to cool for 10-15 minutes in the pan then turn the bread and pan over onto a serving pan. Remove the pan.
Serve with pizza sauce or marinara for dipping.
