I have made oodles of banana shakes in my lifetime, but a friend just suggested a small addition that was a stroke of genius - cinnamon. She was experimenting to make something similar to horchata, which her daughter loves, and came up with this idea. I threw it together today without even measuring, and it was delish! So experiment yourself to see what balance of ingredients you like, but here is the idea:
Rice milk, soy milk or whatever you like...
Vanilla (I used vanilla rice milk and didn't even bother with it)
Sugar, xylitol, honey, etc (I used overripe bananas and didn't need a sweetener at all)
So simple, but so good!
