Heat the oven to 350 F. Grease a 12-cup fluted tube pan very well with baking spray or softened butter, including the center tube.
02 -
Separate the biscuits and cut each biscuit into 4 even pieces. Place the pieces in a large mixing bowl.
03 -
In a small bowl, stir together the melted butter, garlic powder, Italian seasoning, red pepper flakes, black pepper, and Parmesan.
04 -
Pour the butter mixture over the biscuit pieces. Add the mini pepperoni and mozzarella, then toss gently until everything is evenly coated.
05 -
Spoon the mixture into the prepared pan. Do not press it down firmly, since a lighter pack helps the center bake through.
06 -
Bake for 32-38 minutes, until the top is deep golden and the center pieces are cooked through. Cover loosely with foil near the end if the top browns too quickly.
07 -
Let the bread rest in the pan for 8 minutes. Run a thin knife around the edges, invert onto a platter, and sprinkle with parsley.
08 -
Serve right away with warm marinara sauce for dipping.
