Yasso is the first-ever line of frozen Greek yogurt bars to hit the market. In 2009, founders Amanda Klane and Drew Harrington set out on a mission to craft a wholesome and delicious everyday frozen treat. After two years of perfecting their recipe, Yasso Frozen Greek Yogurt Bars were born. Hitting store shelves in mid-2011, Yasso quickly became one of the fastest-growing brands in the frozen novelty category. Made with only natural ingredients, including real Greek yogurt, rBST-free milk and natural sweeteners, Yasso is a great low-calorie frozen treat filled with protein and containing little to no fat. Yasso currently offers bars in Blueberry, Raspberry, Strawberry, Coconut, Mango and Vanilla Bean, and products can be found at major grocery and club stores nationwide.
