Preheat the oven to 350°F (175°C). Spray a bundt pan with non-stick cooking spray.

In a small bowl, whisk together the melted butter, granulated garlic, Italian seasoning, crushed red pepper flakes (if using), and salt. Set aside.

Open the biscuit cans and cut each biscuit into quarters.

Place half of the biscuit pieces in a single layer at the bottom of the prepared bundt pan. Do not press them down.

Sprinkle half of the shredded mozzarella cheese over the biscuit pieces, making sure to fill the gaps. Drizzle half of the butter mixture evenly over the cheese. Add a layer of pepperoni slices.

Repeat the layering process with the remaining biscuit pieces, mozzarella cheese, butter mixture, and pepperoni slices.

Cover the bundt pan tightly with foil and bake for 30 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the top is golden brown and the biscuits are fully cooked.

Let the pizza bread cool in the pan for 5 minutes. Carefully invert it onto a serving plate. Serve warm with pizza sauce for dipping. Enjoy!
