Jamba Juice Peanut Butter Chocolate Smoothie

1 banana, sliced and frozen
1/2 cup chocolate milk (I use chocolate Almond Milk)
1 tbsp peanut butter (I use crunchy)
1 large handful baby spinach

Place all ingredients in blender and pulse until smooth and creamy.
Serve immediately.

Notes

This is a recipe for one. Which means you need to make it in a single serve blender, which you can easily do using a standard blender base and a mason jar (see this post). Or you can double the recipe if you need to use a standard sized blender pitcher, and just freeze any extras for later!

If you'd like to cut down on some of the sugar, feel free to use regular milk (or almond milk) and a tablespoon of dark cocoa powder. I've done this several times and like it a lot-- less sweet (of course), but delicious and super chocolatey!
