Hey I've been making this shake and it tastes almost like a frosty but not as sweet... more of a pure chocolate tastes but still really nice and rich like a frosty. If you added some kind of sweetener it would be exactly the same but I think it's really good without it.
Heres the ingredients:
1 cup of light coconut milk
1 tablespoon of coconut oil
2.5 tablespoons of raw cacao powder
lots of ice, 1.5 cups or so
a bit of vanilla extract
vanilla whey or egg protein powder (i used egg)
Blend it and there you have it. I think the raw cacao powder adds the intensity of the chocolate flavor so if you can, get the raw stuff.
It's about 450 calories depending on the brand of protein powder and coconut milk you use (some light brands are 35% to 50% less than whole coconut milk). So it's probably not good if your trying to loose but it's great as an on the go breakfast or something.
