Blueberry,

I really like Core protein shakes. I buy them in chocolate to drink and also in vanilla to make chia and flax seed puddings. They are made from Fairlife ultrafiltered milk which has had half of its milk sugars and carbs washed out. The results is a high protein, high calcium drink which to me is quite palatable. I buy mine from Amazon in bulk, but you can get a bottle at groceries stores to try. They have recently launched the Strawberry flavor, which I have not tried yet.

If you have pure cocoa powder and milk, I can type up my recipe for a tasty homemade drink. I would add whey protein powder or collagen peptides (a type of protein) to make the drink more filling and nutritious.
