I tried the healthy chocolate cake-batter milkshake off of Chocolate Covered Katie's website and thought it was pretty good. The flavors were really yummy, didn't taste at all like a vegan shake, and you don't need to add any sugar! The only negative I would have to say is that it didn't taste like cake-batter.
That being said, Katie did state on her site that she had never had cake-batter flavored ice cream. So I'm probably comparing it too much to the store bought kind.
Overall, a tasty and healthy treat to try. Just go to her website:
