In a medium bowl, beat cream cheese, garlic powder, onion powder and pepper with an electric mixer until smooth and creamy. Stir in 1 1/2 cups cheddar cheese, and half each of the bacon, jalapenos and green onions.

Spoon the cheese mixture onto a large piece of wax paper or parchment and shape into a ball. Wrap in plastic wrap and refrigerate for at least 8 hours or until firm.

Spread the remaining cheese, bacon, jalapenos and green onions onto a plate. Roll the cheeseball in the mixture to coat well, pressing the toppings into the cheeseball with your hands, if needed.

Serve immediately with crackers, bread or vegetables.
