puff bar

Most puff bars come in two common protein amounts: 15 grams or 17 grams of protein per bar.

Product listings show whey protein isolate as the primary dietary protein used in these puff bars.

Reviews and descriptions commonly report a soft, marshmallow-like or puff interior with a light, chewy mouthfeel—not the dry or chalky texture associated with some protein bars.

Reviews describe a candy-bar or dessert-like overall flavor and generally report little to no chalky or off protein aftertaste.

A small number of reviewers say refrigerating or freezing can improve texture, while isolated reports note bars arriving softened when exposed to heat during shipping.
