Chop the bananas into smaller pieces. Or at the very least, break it in half.
Add all of the ingredients to the blender, adding the ice last.
Blend the ingredients until smooth.
Top your smoothie with melted peanut butter and/or banana pieces. (optional)
Enjoy!

Notes
Feel free to add 1 to 2 Tablespoons of cocoa powder to turn this into a chocolate peanut butter smoothie.This smoothie tastes best right away, but you can store the leftovers, covered in the fridge for about 24 hours. Just give it a good stir when you take it out of the fridge.
