Three different Puff Built Bars and five regular bars were ranked by @eyeshadow__lover_, who regularly carries a protein bar with her for an on-the-goal meal replacement. Her favorite flavors typically contain chocolate, which is why she was so surprised to see her least favorite bars have chocolate-related attributes.
For example, her least favorite bar was the Peanut Butter Brownie, while her top pick was the Cookie Dough Chunk. She describes the puffier bars as "chocolate-covered marshmallows" and the regular bars as "chocolate-covered caramel" in terms of texture.
In order from worst to best, she ranked Peanut Butter Brownie, Mint Brownie, Salted Caramel, Cherry Barcia, Brownie Batter, Raspberry, Churro, and Cookie Dough Chunk. Though the Built company has excellent customer service, the bars are not very accessible since they can only be purchased online.
You can purchase Built Bars on Amazon (12 packs for $29.95 or about $2.50 per bar).
