Preheat your oven to 350°F and grease a Bundt pan.

Mix the olive oil, butter, onion flakes, garlic, Italian seasoning, red pepper flakes, and parsley in a microwave-safe bowl, then microwave until melted.

Cut refrigerated pizza dough into 1.5-inch pieces and quarter the biscuits.

Layer a third of the pepperoni and Parmesan at the bottom of the Bundt pan.

Toss the dough pieces in the oil mixture until well-coated, then layer half of them into the Bundt pan.

Sprinkle half of the remaining pepperoni, Parmesan, drizzle some marinara, and add half of the mozzarella over the initial layer.

Top with the remaining dough pieces, then add the last of the marinara, pepperoni, Parmesan, and mozzarella.

Bake for 40 minutes until golden brown and cooked through.

Cool in the pan for 10 minutes before removing.
