I have just discovered smoothies....I know, I am shocked too. Each morning, I would mix my protein powder with milk, shake, and quickly drink it to get out of the house on time. But for the last year, what sits on my counter but a blender that has little smoothie mixing cups for what else....yeah, smoothies!!! So when I caught up to this fact, I started experimenting as I wanted it to stay thick for at least an hour and it had to be creamy. I also wanted to make a batch that would last for 4 days so that in the morning, all I have to do is add the smoothie mixture, any add in and ice. These never get watery. Very simple and I think they are fantastic.
