Sour Protein Bars

BUILT Sour Puff is Sweet & Tart on the Outside and Marshmallowy Inside

Protein bars are becoming more like candy bars as consumers demand products that deliver decadent flavors, satisfying textures and nutrition in a convenient bite, and BUILT Sour Puff sets itself apart on two counts—it has an irresistibly soft center and a sweet-tart coating. Flavor is important, and BUILT Sour Puff delivers deliciously different varieties like Blue Razz Blast Charge, juicy Sweet Peach Punch, and crisp Green Apple Crush.

Light, protein-rich BUILT PUFF with a marshmallowy middle now sports a fresh new look that focuses on flavor and candy bar-like indulgence. “We have consumers who have referred to our product as ‘purse candy,’ and so we had to have a package design that lived up to that promise,” said Megan Crossland, chief commercial officer at BUILT.
