Fantastic protein. Flavor was on point it mixed well I use milk in a shaker bottle and it mixes easily. It even has little pieces of birthday cake like confetti I love it. It's been easy on my stomach and digest well.

2025- something has changed in the formula. While it tastes ok, it's not as strong of a cake batter flavor as it used to be, there are less of the little chocolate things, and it does not dissolve as well if you're mixing with water. The cake batter is still way better than the cookie dough (which tastes nothing like cookie dough) but it's not as good as it used to be.

Taste and quality are king with this product. I used to buy protein powders in bulk and then add flavoring and extra ingredients to get the taste and texture just right. While that worked, it took longer and involved measuring ingredients for consistency. With this powder, the taste and texture are built in, making it easy to down with only water or milk. Going forward, I think I’ll stick with this product line for a while, trying different flavors to see which I like best.
