Combine olive oil and ½ teaspoon of garlic powder in small bowl.
Grease a bundt pan or 9x13 baking dish and a large mixing bowl with the olive oil mixture, reserving about 1 tablespoon of the mixture.
Lightly flour a cutting board or working surface. Roll the dough out into a 12 inch by 9 inch rectangle--or something of that nature. Cut into 1 inch cubes.
Grease a large mixing bowl with olive oil. Add the dough cubes, mozzarella, Parmesan cheese, Italian seasonings, 1 teaspoon garlic powder, crushed red pepper flakes, a small pinch of salt, and up to 1 cup of pizza toppings of your choice. Toss to evenly distribute ingredients.
Spread the dough mixture evenly in the bundt pan or baking dish and brush the remaining olive oil evenly over the top of the dough.
Cover the bundt pan with a towel and let the dough rest while the oven heats to 350 degrees Farenheit.
Bake at 350 for 30-35 minutes if using a bundt pan, or 15-20 minutes if using a baking dish, until bread is cooked through and golden brown. Check the pizza bread halfway through cooking. If you notice the top is browning before the dough is cooked through, cover with foil for the remaining of the bake time.
Remove from oven and let cool for 5 minute in pan. Serve right from baking dish, or if a bundt pan was used, carefully remove the pizza bread from the bundt pan, using a knife to loosen from the sides of the pan if needed. Invert the bread and serve with pizza sauce or marinara sauce.
If you want to cut this recipe in half, use only 1 pound of pizza dough and bake in a 9x9 greased pan for 15-20 minutes.
If using canned pizza dough, use 2 (13.9 ounce) cans and proceed with the recipe as stated.
Use any toppings as desired, but it is best to limit toppings that are high in moisture (like peppers, mushrooms, and spinach) to no more than ½ cup, so that the dough does not become soggy.
If you would like to add pizza sauce to your pull apart pizza bread, add no more than ¼ cup to the dough mixture before baking.
