Substances You’ll Want
- Frozen Banana. Utilizing a frozen banana is vital to this recipe, because it provides the smoothie an ice cream-like texture. Whereas a number of commenters have reported utilizing a contemporary banana, too, you’ll get probably the most milkshake-like texture with a frozen one.

That is completely non-obligatory! When you want a vegetarian recipe, go away this out. (I don’t suggest utilizing a sweetened protein powder except you understand you completely love the flavour. Most flavored protein powders don’t style good to me.)
