Place the soured cream, whey protein powder and water into a blender. 

You can use vanilla beans or sugar- free vanilla extract. If using vanilla beans, cut them lenghtwise and scrape the tiny seeds out. You can use either whey protein or egg white protein powder or collagen powder. 

Add the eggs and stevia. If you are worried about using raw eggs, try ground chia seeds or coconut butter instead 

Add MCT oil and ice. Note: If you don't have any, use coconut oil. Just make sure you blend it well or the coconut oil will clump up. Unlike MCT oil, coconut oil solidifies when chilled.) 

Pulse until smooth and frothy and serve immediately.
