Preheat your oven to 450°F (230°C).
Roll out your pizza dough on a floured surface to your desired thickness.
Transfer the rolled dough to a pizza stone or baking sheet.
In a bowl, mix shredded chicken with buffalo sauce until well coated.
Spread the buffalo chicken evenly over the pizza crust.
Sprinkle mozzarella cheese generously over the chicken.
If using, add blue cheese crumbles on top.
Bake in the preheated oven for 15-20 minutes, or until the crust is golden brown.
Remove from oven and let it cool for a few minutes.
Drizzle with ranch dressing and garnish with cilantro or green onions before serving.
