Preheat oven to 425 degrees (400 degrees if using thin crust)
In a small bowl combine 6 tablespoons butter and 3 cloves minced garlic. Heat together in the microwave until partially melted.
Brush garlic butter into the bottom and sides of the muffin pan cups ensuring each cavity is well greased. To the leftover garlic butter, add the remaining ingredients: parmesan, parsley and red pepper flakes.
Roll out the dough to approximately 10x15 rectangle, cut into 12 equal sized circles (use the lid of a glass for this). Press the dough into each muffin cup, working it up the sides.
Start with a thin layer of cheese at the bottom (to prevent sogginess), then a spoonful of diced chicken, a hefty dollop of sauce and a spoonful of bacon pieces.
Finish off each pizza puff with a rooftop of mozzarella cheese. Use a large handful to cover the tops of each cup.
Bake in preheated oven for 10-14 minutes, turning the pan halfway through.
Reheat the leftover garlic parmesan butter in the microwave until it's partially melted and use a basting brush to coat the tops of each pizza puff with butter topping. Serve with warm leftover alfredo sauce.
