Hands down, one of the best party appetizers ever, ever!

Combine Ingredients: In a medium bowl, mix together the softened cream cheese, shredded cheddar cheese, crumbled bacon, chives, garlic powder, and black pepper.
Form Cheese Balls: Shape the mixture into 1-inch balls using your hands or a small cookie scoop. Place them on a parchment-lined baking sheet.
Coat Cheese Balls: Combine the remaining crumbled bacon and pecans in a small bowl. Roll each cheese ball in the mixture to coat.
Chill: Refrigerate the cheese balls for at least 30 minutes to firm up.
Serve: Serve chilled.
