It is important to make sure you are using softened cream cheese, otherwise you will not have a smooth creamy texture for your smoothie. 

It is best to let your cream cheese soften at room temperature. If you are short on time, you can cut your cream cheese into small cubes and it will soften in about 15 minutes. If you do not have time to let it soften this way, you can microwave it using short 10 second intervals. 

Once you have softened your cream cheese, add all the ingredients to a blender and blend well adding ice as needed.
