Add ½ cup crunchy Cheetos to food processor bowl. Secure lid on food processor and pulse until Cheetos are ground to dust. Set food processor aside. Note: Alternately, place ½ cup Cheetos in sealable plastic bag and beat Cheetos with rolling pin until smashed into dust. Set aside.
Position oven rack in middle or lower-middle of oven. Place baking sheet or pizza stone on center of oven rack, then preheat oven to 475° Fahrenheit.
Cover flat work surface with sheet of parchment paper, then dust parchment paper evenly with cornmeal.
Place ball of pizza dough on parchment paper. Using hands, form and stretch ball of dough into thick, even disc shape. Work quickly, as body heat and ambient temperature will make dough wet and sticky. Lightly apply cornmeal to hands if needed to help with sticking.
Cover dough with second sheet of parchment paper, then use rolling pin to roll dough into large circle, 12 inches in diameter and approximately ¼-inch thick. Work from center of dough outward toward edges, and keep dough evenly thick across entire disc. Don't worry if dough is not perfectly round at edges. Note: Alternately, use hands instead of rolling pin and stretch dough into desired shape and size, being careful to avoid leaving excessively thick or thin spots.
With top sheet of parchment paper still covering pizza dough, carefully lift bottom sheet of parchment paper up off of work surface. Swiftly flip stack over, keeping dough sandwiched between parchment paper, so that bottom sheet of parchment paper is now on top of dough.
Carefully peel away top sheet of parchment paper and lightly dust pizza dough evenly with cornmeal.
If using pizza peel, use parchment paper beneath pizza dough to flip dough over onto pizza peel. Remove parchment paper and discard.
If not using pizza peel, recover dusted dough with parchment paper. Flip stack over again so cornmeal-side of dough is on bottom, then remove top sheet of parchment paper and discard.
Working quickly, top dough with ½ cup pizza sauce. Use back of spoon or measuring cup to spread sauce evenly across entire pizza, leaving approximately 1-inch-wide border of uncovered dough around edge for crust.
Top pizza sauce with 1 ½ cups shredded mozzarella, making sure to spread cheese out into one even layer if possible. Sprinkle Cheeto dust from food processor evenly over top of mozzarella. Note: Reserve 1 tablespoon Cheeto dust to use in garlic-butter sauce if making.
If using pizza peel, carefully transfer pizza onto baking sheet or pizza stone in preheated oven. If not using pizza peel, carefully pull oven rack out of oven as needed, then slide or place parchment paper with pizza directly onto baking sheet or pizza stone. Return rack to oven.
Bake pizza 5 minutes, then check doneness. Rotate pizza as needed if pizza begins to brown unevenly. Continue baking pizza, checking doneness every 2 minutes, until cheese has melted and crust is rich, golden brown. If using garlic-butter sauce for crust, prepare sauce while pizza bakes.
