Built Puffs are here! What are Built Puffs, you ask? Well, they are a bit of heaven on earth. Marshmallow heaven, that is. The first and only protein-infused marshmallow on the market, Built does it again. It has a delicious coconut flavor, and, of course, it is covered in Built’s signature 100% chocolate. You will quickly forget this is a protein bar, thinking of it more as a tasty treat. Feel good about that.
