Preheat your oven to 475°F (245°C). If you’re using a pizza stone, place it in the oven while it heats up to ensure a crispy crust.
On a lightly floured surface, roll out your store-bought pizza dough into a round shape, about 12 inches in diameter. If the dough is resistant, let it rest for a few minutes before rolling.
Carefully transfer the rolled-out dough to a pizza stone or a baking sheet lined with parchment paper.
In a mixing bowl, combine the sliced grilled chicken with the Frank's Red Hot Buffalo Wings Hot Sauce. Make sure the chicken is well coated.
Lay the white American cheese slices evenly over the pizza dough, leaving a small border around the edges for a crust.
Evenly distribute the Buffalo chicken mixture atop the cheese. Sprinkle the thinly sliced white onions over the top for an extra layer of flavor.
Place the pizza in the preheated oven and bake for 12-15 minutes, or until the cheese is melted and bubbly, and the crust is golden brown.
Once baked, remove the pizza from the oven and let it cool for a few minutes. Slice into wedges and serve hot. Enjoy your homemade Easy Copycat Dominos Buffalo Chicken Pizza!
