Get a decent sized blender or Blentec/Vitamix.
(or anything that can blend up ice)
Add all the ingredients (except ice) together in the blender and mix until well blended.
It will be liquidy at first, but the psyllium fiber/chia seeds will thicken it as they absorb the liquid and expand.
Add extra tsp if not thicker than a liquid if it seems too runny.
The secret to good blender ice cream is to make the initial mix nice and thick.
Add your ice.
The amount of ice depends on your blender, but I added about 10 cubes to fill the blender to the top.
Double the liquids and add the same amount of ice for a smoothie of sorts.
Will keep in the freezer for a few weeks.
Enjoy as a dessert or a pick me up in the morning.
