01 - Preheat oven to 400°F and line a baking sheet with parchment paper.
02 - In a large bowl, combine ground chicken, breadcrumbs, egg, celery, green onions, garlic, salt, pepper, and onion powder. Mix until just combined; avoid overmixing.
03 - Using damp hands or a small scoop, form mixture into 1 1/2-inch balls and place on the prepared baking sheet.
04 - Bake for 18–20 minutes until meatballs are cooked through and lightly browned.
05 - While meatballs bake, whisk together hot sauce, melted butter, and honey in a large bowl until smooth.
06 - Add cooked meatballs to the bowl with buffalo sauce and toss gently to coat evenly. Serve immediately with blue cheese or ranch dressing, celery, and carrot sticks if desired.
