Apple slices and nut butter are a favorite after-school snack, and they taste just as satisfying in this smoothie. Pick your favorite nut butter: cashew for a less-prominent nutty flavor, or almond or peanut butter for a stronger taste.
Add kale, apple, cashew butter (or other nut butter), honey, ice cubes and almond milk (or other milk) to a blender. Blend on medium-low speed, using the tamper as necessary, until well combined.
Increase speed to medium-high and blend until very smooth.
