In a mixing bowl, combine the softened cream cheese, Greek yogurt, and buffalo sauce. Mix until smooth and well-blended.
Add the shredded chicken, garlic powder, half of the shredded cheddar cheese, and half of the chopped green onions into the mixture. Stir until everything is evenly coated.
Season with salt and pepper to taste. Adjust the amount of buffalo sauce for desired spiciness.
Transfer the mixture into a baking dish, spreading it evenly.
Sprinkle the remaining shredded cheddar cheese on top.
Bake in the preheated oven for about 20-25 minutes, or until the dip is heated through and the cheese is melted and bubbly.
Remove from the oven and let it sit for 5 minutes before serving.
Sprinkle the leftover chopped green onions on top for garnish.
Notes
Serve warm with tortilla chips and veggie sticks for a festive touch.
