Preheat the oven to 475ºF and position 2 racks in the center. Line 2 baking sheets with parchment paper; set aside.
In a saucepan, combine firecracker sauce ingredients over medium-high heat. Bring to a boil, then reduce heat to simmer. Let it simmer for 8-10 minutes. Remove from heat and allow the sauce to cool; it will thicken as it cools.
In a large bowl, mix ground chicken, minced garlic, salt, pepper, eggs, Panko breadcrumbs, paprika, and onion powder. Use your hands for thorough mixing. Avoid overmixing to prevent dry meatballs.
Shape the meat mixture into balls, approximately 3 tablespoons per ball. Alternatively, use an ice cream scoop for consistency. Place shaped meatballs on the prepared baking sheet.
Bake for 11-13 minutes or until meatballs are fully cooked.
Using 2 tablespoons, dip each meatball into the sauce, or brush each meatball with the sauce. Return to the baking sheet and bake for an additional 1-2 minutes.
Drizzle or brush with additional sauce as desired before serving.
