Optional additions: a handful of spinach, a scoop of protein powder, and/or 1/2 teaspoon of instant espresso powder
Instructions
Cube the bananas and place in a freezer bag. Freeze for at least 8 hours, or up to a week in advance.
Pour chocolate almond milk into blender. If using spinach, protein powder, or espresso powder, blend these with almond milk on high until smooth.
Then, add frozen banana chunks and blend on high until just the bananas are just combined (over-blending will lead to a thinner smoothie). Drink immediately or place in freezer for up to 20 minute before enjoying.
Notes
It's worth noting that while the ingredients for the smoothie are healthy, the smoothie is still a bit high in sugar since bananas have lots of natural sugar and the chocolate almond milk has some sugar, as well. So, if you're carefully limiting your sugar intake, this smoothie (or any smoothie, really) may not be the best choice.
