The cinnamon roll flavor is absolutely delicious! I have drank it in almond milk and I have also made low carb pancakes with this and it tastes like you are eating a cinnamon roll for breakfast. Definitely will be reordering more after this bag!

Purchase arrived earlier than expected.. I ordered the double chocolate, which tastes better than many of the other protein powders out there.
