Add softened cream cheese, white cheddar cheese, Dijon mustard, and garlic powder in a large bowl and mix until they are well combined. Then mix in the chopped cranberries.

Lay a large piece of plastic wrap flat on the counter. Scoop out your cheese mixture into a ball in the middle of the plastic wrap. Wrap the plastic around the cheese mixture and press into a slightly flattened ball. Let chill in the refrigerator for at least an hour.

While your cheese ball is in the refrigerator, shell your pistachio and chop them into small pieces.

Remove the cheese ball from the refrigerator and unwrap it. Take small handfuls of chopped pistachios and press them into the cheese ball. Do a little at a time until the ball is covered. You do not need to add pistachios to the bottom of the cheese ball. In fact, leaving some of the cheese exposed will help the ball stick to its serving plate, which will make it easier for your guests to scoop.

The cheese ball is ready to serve with sturdy party crackers! You can make this ahead of time and store in the fridge.
