Preheat oven to 350. Prepare a baking dish with a piece of tinfoil.

Combine corn starch, brown sugar, chili powder, salt and garlic powder in a large bowl.

Add chicken wings and toss. Allow to sit for 10 minutes, allowing the spice mixture to absorb into the wings. Toss again, letting to sit another 5 minutes.

Place wings on the baking sheet and bake for 20 minutes.

Remove from oven and flip over. Cook for another 20 minutes.
