In a mixing bowl, combine the softened cream cheese with the shredded white cheddar cheese. Blend until smooth and creamy, about 2–3 minutes.

Add garlic powder, onion powder, and black pepper to the cheese blend. Mix thoroughly for another 1–2 minutes until the spices are evenly distributed.

Shape the mixture into a cohesive ball and wrap tightly in plastic wrap to maintain its shape.

Place the wrapped cheese ball in the refrigerator and chill for at least 1 hour for flavors to meld.

Unwrap the cheese ball and transfer it to a platter. Use black olives to create facial features for Jack Skellington.

Serve with an assortment of crackers, sliced veggies, and fruits on the platter.
