Whisk ingredients together. Freeze in shallow containers or an ice cube tray .
Once frozen, pop the blocks out.
Thaw until just soft enough for your blender to be able to handle it. Blend until desired slushiness is reached.
Add extra sweetener if needed, but do not add ice, because it would dilute the flavor.
Feel free to add cocoa, cinnamon, berries, chai, banana, or other flavors if you wish.
