We recently watched an episode of Daniel Tiger's Neighborhood. There was a recipe for banana swirl. They showed how to make it, but it seemed way to easy. I had to give it a try. Sure enough it is that easy. I think it is a great option for food allergic people because it is one single ingredient -- Bananas. Granted you are no allergic to bananas.
Banana Swirl (aka banana ice cream)
2 frozen bananas
1. Freeze bananas for a few hours.
2. Place frozen bananas in blender. Blend on medium-low for about a minute or two.
3. The mixture will resemble ice cream in texture.
4. Add sprinkles, chocolate sauce or honey (or anything you think goes with bananas).
You will be so impressed with this -- you have to try it. Enjoy!
