Preheat oven to 400°F. Line a large sheet pan with foil or parchment. Spread chips in an even layer.
Melt butter gently. Whisk in hot sauce, garlic powder, onion powder, paprika, salt, and pepper until smooth.
Toss warm sauce with shredded chicken, using about half, until evenly coated.
Layer half the chips, chicken, and cheeses on the pan; repeat to create a second layer.
Bake until cheese is melting and edges crisp, 10–12 minutes.
Drizzle remaining buffalo sauce and ranch. Scatter jalapeños, green onions, celery, blue cheese, and cilantro.
Serve hot right from the pan. Add extra sauce or ranch to taste.
Notes
Swap ranch with blue cheese dressing for a bolder bite, or add diced tomatoes for freshness. For make-ahead, mix the buffalo chicken up to 2 days early and reheat gently before assembling. Bake just before serving for best crunch.This recipe is an original creation inspired by classic Buffalo Chicken Nachos Recipe flavors.
