Place the banana, dates, almond butter, vanilla extract, and almond milk in a high powered blender (if you do not have a high-powered blender, I recommend blending the milk and half of the frozen fruit first, then slowly adding the rest of the fruit and remaining ingredients).
Blend until smooth. If you would like the shake a bit thicker, add a few ice cubes and blend again. Taste and add additional almond butter if you'd like the shake a little richer or another date if you'd like it sweeter. Pour and enjoy!
