Whisk together the ingredients in a very large bowl.
Transfer the mix into jars, tightly seal, and store in a cool, dark place, such as the pantry. To use, add 1 tsp of the mixture into a blender or shaker cup along with 1 cup of liquid (water, milk, juice, etc.).
Blend or shake vigorously. It will thicken the longer the mixture sits, so add more liquid if you don't like it like that.
