Using a stand or hand mixer on medium speed, beat your cream cheese, sour cream, garlic powder, onion powder, and black pepper until smooth and creamy. Turn to low and mix in 1 1/2 cups of cheddar cheese, half of the chopped bacon, half of the minced jalapeno, and half of the chopped green onions. Combine your reserved cheddar, bacon, jalapenos, and green onions in a small zipper storage bag and store in the refrigerator.
