Preheat the oven to 425℉ (220℃) and lightly grease a 12-inch pizza pan.
If making Homemade Buffalo Sauce, combine ½ cup cayenne pepper hot sauce, ½ tablespoon apple cider vinegar, 2 tablespoons unsalted butter, ½ teaspoon garlic powder, and ½ teaspoon Worcestershire sauce together in medium saucepan. Bring to a simmer over medium-high heat. Once simmering and the butter has melted, turn off the heat. Add ½ tablespoon honey and stir to combine. Skip this step if using prepared buffalo sauce.
In a medium mixing bowl, combine 2 cups cooked chicken (diced or shredded) with ¾ cup buffalo sauce and toss until the chicken is coated in the sauce.
On a lightly floured surface, roll out 1 pound pizza dough, using a rolling pin to about ¼-inch thickness. Carefully transfer the crust to the greased pan.
Using a slotted spoon, to remove excess sauce from the buffalo chicken mixture, transfer the chicken onto the prepared crust and spread the mixture evenly over the pizza crust, leaving about a ½ to 1-inch border around the edges of the pizza crust. Sprinkle 4 ounces sharp cheddar cheese (shredded) and 4 ounces mozzarella cheese (shredded) evenly over the chicken mixture to cover.
Bake for 15-18 minutes, or until crust is browned evenly and cheese is fully melted.
Remove the pizza from the oven and let cool for 10 minutes before slicing. Serve the pizza with a drizzle or a side of dressing as desired.

Notes
Chicken Option: Use Instant Pot Buffalo Chicken in place of leftover chicken, hot sauce, garlic powder, and butter. Storage: Leftover pizza can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in a 300℉/150℃ oven for 10-12 minutes, or until warmed through.
