In a small blender or NutriBullet, blend together the solid coconut cream, water, vanilla, and stevia until well blended.
Add more or less stevia to taste, and add more or less cream for thickness
Store this in a sealed container or jar in the fridge and stir as needed to address any separation
* If you don't have access to coconut cream, you can use 1-1/2 cups of your favorite full-fat canned coconut milk here if it's thick and is not separated. If you open a can of full-fat coconut milk and it's separated, just put it in a blender for a bit to mix it together
