In a bowl, combine Coca-Cola, soy sauce, brown sugar, garlic, and ginger.
Add the chicken wings and marinate for at least 30 minutes.
Preheat the oven to 375°F (190°C).
Place wings on a baking sheet lined with parchment paper and bake for 40 minutes, flipping halfway through.
Transfer marinade to a saucepan and bring to a simmer.
Mix cornstarch and water, then stir into the sauce until thickened.
Brush the thickened sauce over the baked wings and return to the oven for 10 minutes.
Garnish with sesame seeds and green onions before serving.
