*If you don’t have peanut butter powder, 2 tablespoons of peanut butter may be used instead—or almond butter for a slightly different flavor. To avoid overpacking the peanut butter powder, measure it like flour, scooping into the measuring cup and then leveling with the straight edge of a knife. That said, a little more or less either way won’t hurt.
To make smoothie packs: Place blueberries, sliced banana, peanut butter powder, and raw spinach in a freezer bag. Label and freeze for up to three months. To make the smoothie, add the coconut water or milk of choice to blender, followed by the contents of the smoothie pack, and blend until smooth. I usually need an extra 3-4 tablespoons of liquid when using the frozen packet.
