Preheat the oven to 350°F and coat a large Bundt pan (10 to 12 cups) with nonstick cooking spray.
In a microwave-safe bowl or on the stovetop melt the butter and then mix in minced garlic, and red pepper flakes. Let cool slightly while cutting the biscuits.
Cut each biscuit into quarters (4 pieces) and add to the cooled mixture in a large bowl or large zip-lock bag; toss to coat.
Layer half of the butter garlic biscuit into the bottom of the prepared baking pan. Sprinkle half the of the Parmesan, shredded cheese, and parsley over the top. Turn to coat the biscuit with cheese and parsley.
Repeat the layer, turning to coat the biscuits.
Bake for about 40 minutes or until the garlic bread is golden. Cool in the pan for 10 minutes before inverting onto a platter.
