See More ReviewsI was expecting it to be so thick of a shake, use 12 oz instead of 8 oz (milk or water) and it’s good to drink. This flavor is delicious. It’s a bit grainy, but not too off-putting, and I have gotten used to it. I look forward to these shakes at the end of the day (instead of dessert)!
