I love this protein bar! It is like no other. It tastes like a sour candy marshmallow but healthy. Great healthy ingredients too.

This one also tastes as one would expect. It's a protein bar that has a textureThat tries to mimic a very thick marshmallow. I would not call it a marshmallow myself but that's what they're aiming for. It's much more of a rubbery texture than a fluffy marshmallow. This particular flavor is interesting because it's a blue raspberry but sour candy type of flavor. It's strange but oddly works.
