Preheat oven to 400 degrees Fahrenheit (200 degrees Celsius).
In a blender or food processor, combine cottage cheese, buffalo sauce, honey, and sriracha. Process until completely smooth.
In a large mixing bowl, toss the cubed chicken with garlic powder, onion powder, smoked paprika, and cornstarch until evenly coated.
Pour the blended cottage cheese sauce over the chicken and stir to combine.
Transfer the mixture to a 9x9 inch baking dish, spreading it in an even layer.
Bake for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165 degrees Fahrenheit.
Top with shredded mozzarella and place under the broiler for 2 to 3 minutes until the cheese is melted and bubbly.
Garnish with sliced green onions before serving.
