Preheat your oven to 450°F. If you have a pizza stone, place it in the oven while preheating for optimal results.
In a bowl, mix the shredded chicken with buffalo sauce and 1 tablespoon of blue cheese dressing. Allow it to marinate while you prepare the other ingredients.
Roll out the pizza dough onto a lightly greased 12-inch pizza pan or stone. Use a fork to poke holes in the dough to prevent bubbling.
Spread pizza sauce over the dough, followed by most of the mozzarella cheese.
Add the marinated chicken, sliced red onions, and banana pepper rings on top of the cheese.
Drizzle with 3 tablespoons of blue cheese dressing and 1-2 tablespoons of buffalo sauce.
Bake the pizza for 13 minutes, then remove it from the oven.
Combine melted butter, Parmesan cheese, and garlic powder. Brush this mixture over the crust of the pizza.
Return the pizza to the oven and bake for an additional 2-3 minutes, or until the crust is golden brown.
Garnish with chopped chives, red pepper flakes, and parsley before slicing and serving.
