Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
Pat chicken wings dry with paper towels.
In a large bowl, toss wings with baking powder, salt, pepper, and garlic powder until evenly coated.
Arrange wings in a single layer on the prepared baking sheet. Avoid overcrowding; use two baking sheets if necessary.
Bake for 45-50 minutes, flipping halfway through, until wings are cooked through, crispy, and golden brown, reaching an internal temperature of 165°F (74°C).
While wings are baking, prepare the sauce. In a small saucepan, combine hot sauce, honey, brown sugar, soy sauce, rice vinegar, ginger, garlic, and red pepper flakes.
Heat sauce over medium heat and simmer for 5-7 minutes, stirring occasionally, until slightly thickened.
Once wings are cooked, transfer them to a large bowl and pour the firecracker sauce over them. Toss to coat wings evenly.
Serve immediately, garnished with sesame seeds and chopped green onions, if desired.
