I've recently run into a snack that stops my sweet tooth dead in it's tracks. The ingredients are really complicated
1 frozen banana.... that's it.
I peel and freeze ripe to over ripe bananas. I then put one in a nutribullet blender. It turns the banana into the consistency of high end ice cream. It's bizarre how much better this tastes and feels over just eating a banana.
I was reluctant to buy the nutribullet as they have really cheesy advertising, think Ginzu knives

, but so far it's holding up well and it's easy to clean. One drop of soap and a bit of water, then turn it on for a few seconds, rinse and done.
This is a bit different than a smoothie, it's just like ice cream.
