Add the milk, bananas, agave nectar, vanilla extract, and cinnamon into a blender.
Blend until completely smooth.
Pour into glasses, garnish with a sprinkle of ground cinnamon, and serve immediately.
Notes
The level of sweetness of your licuado can depend on the ripeness of your bananas. The riper your bananas, the sweeter and stronger the banana flavor will be. You can adjust the agave syrup according to your preference or omit it completely if you don’t want to add extra sweetness.
I used whole milk in this recipe to make it more filling, but you could use nonfat milk or even your favorite dairy-free milk or milk alternative. Oat, cashew, or almond milk are all great options.
