Add the frozen bananas, almond milk, and cocoa powder to a high-speed blender.
Blend until smooth.
Pour into a milkshake glass and add your favorite toppings!
Enjoy!
Notes
Use any plant-based milk that you like the taste of.
If you want your milkshake sweeter, add some pure maple syrup until it's as sweet as you'd like.
If your banana is not ripe, it will leave your milkshake having a bitter/sour-like taste. For sweetest taste, freeze your bananas once they are extra ripe.
If you want a thicker milkshake, try adding up to ½ cup of almond milk or a high fat milk such as coconut milk.
