This blueberry banana smoothie is so simple to make and it really satisfies your sweet tooth without adding any extra sugar. This is my late-night splurge when I'm trying to stay away from the ice-cream. It lets me snack and get a boost of energy before bed (important when you have twins who don't believe in sleep) and it satisfies my craving for something sweet. This smoothie has no added sugar and it's packed full of great nutrients from the bananas and blueberries.
