Tried this the other day...

2 frozen bananas (i peeled them earlier and ziplocked them)
2 scoops of CanadianProtein.com chocolate isolate
1 tbs of natural peanut butter.
splash of unsweetened almond milk

i put it all into my NutriBullet and blended that bad boy for 45 seconds and voila i had a great tasting frozen ice cream/ pudding thingy. Satisfied my sweet tooth!
